• Your initial post should be at least 200 words in length.
Post 3: Response post to a second classmate or the instructor’s follow-up question is due by the end of day on Tuesday.
You recently helped your patient review a denied insurance claim for a routine diagnostic test. The insurance company stated the service was not medically necessary, even though the test was ordered by their doctor to monitor a chronic condition. This experience left you questioning how insurers determine what is "necessary" and why claims for essential care can be denied in some cases.
In your post, share your thoughts on how medical coders and healthcare providers can work together to minimize claim denials based on medical necessity. What steps can be taken to ensure that documentation and coding align with payer policies? Have you or someone you know faced a similar issue with insurance coverage? How would you address these situations in your future healthcare role?

Medical coders and healthcare providers play a crucial role in ensuring that insurance claims are approved, especially when it comes to proving medical necessity. From my perspective, strong collaboration between these two groups is essential to minimize claim denials. Providers need to clearly document the patient’s condition, symptoms, and the rationale for ordering specific tests or treatments. Coders, on the other hand, must accurately translate this information into codes that reflect the true nature of the care provided and match payer requirements.
One important step is ongoing education for both providers and coders about current insurance policies and guidelines. Regular training sessions can help everyone stay updated on what insurers consider medically necessary and how to properly document and code those services. Additionally, using checklists or templates during documentation can ensure all required details are included, such as the diagnosis, relevant history, and the reason for the test or procedure.
I have seen family members struggle with denied claims for tests their doctors said were needed. In those cases, appeals were often successful when additional documentation was provided, showing why the service was essential. If I encounter similar situations in my future healthcare role, I would advocate for thorough documentation from the start and work closely with coders to make sure everything aligns with payer policies. I would also educate patients about the importance of clear communication with their providers regarding their health needs and insurance coverage. Ultimately, teamwork and attention to detail are key to reducing unnecessary denials and ensuring patients get the care they need.
**Response 2: Robie OgnibeneTop of Form**
Insurance denials based on “medical necessity” can be really confusing, especially when a doctor clearly ordered something for a valid reason. After helping a patient review a denied claim for a routine test, I started wondering how insurers decide what counts as necessary in the first place. It made me realize how important it is for medical coders and healthcare providers to work closely together to prevent these kinds of issues.
One big way to reduce denials is making sure the documentation fully explains why the test or procedure was needed. Providers have to clearly describe the patient’s symptoms, history, and diagnosis so coders can match the correct ICD-10 and CPT codes. Coders also play a major role by checking payer policies, catching missing details, and helping providers understand what insurance companies expect. Even small gaps in documentation can lead to a denial, so communication between the coding and clinical teams is key.
I’ve seen people I know run into the same problem—insurance denying something that their doctor felt was necessary. Most of the time, it came down to how the information was documented. In my future healthcare role, I would try to address these issues early by double-checking payer requirements, making sure charts are complete, and helping patients appeal denials when needed. At the end of the day, patients deserve care without unnecessary obstacles.

Unit Lesson
Lesson: Diagnostic Medical Coding (ULOs 2.2 and 3.1)
Introduction
Diagnostic coding is a critical aspect of medical billing and healthcare documentation, ensuring accurate
representation of a patient's diagnosis for clinical as well as administrative purposes.
Consider a scenario where a patient presents with shortness of breath and fever. Initially, the diagnosis might
be documented as pneumonia. However, modern diagnostic coding enables the addition of specificity, such
as "J18.9" for unspecified pneumonia or "J15.9" for bacterial pneumonia, depending on lab results. This
precise coding ensures the patient’s treatment aligns with their exact condition and allows for proper
insurance reimbursement. This unit will cover the basics of diagnostic coding, the International Classification
of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) system, and medical necessity. First, let's
discuss the importance of understanding human anatomy and physiology when it comes to medical coding.
Human Anatomy and Physiology
Understanding human anatomy is an essential skill for medical coders as it helps them identify and apply
codes based on the location and nature of medical conditions. As outlined in the previous example,
understanding the anatomical distinctions between the upper and lower respiratory tract is critical when
coding for conditions like bronchitis versus pneumonia.
This is one reason why human anatomy and physiology should be a course that health information
professionals take early in their educational journey. A solid grasp of anatomy helps coders interpret clinical
documentation effectively, resulting in assigned codes that accurately reflect the patient's diagnosis and
treatment. This leads to improved quality of care and more efficient reimbursement processes.
International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM)
Diagnostic coding is governed by the International Classification of Diseases, 10th Revision, Clinical
Modification (ICD-10-CM). This standardized system, developed by the World Health Organization (WHO)
UNIT V STUDY GUIDE
Diagnostic Medical Coding
HTH 2305, Health Information Documentation Management 2

Title
and modified for use in the United States, is used to document and track diseases and other health
conditions. With over 70,000 codes, the ICD-10-CM system offers a high level of detail, enabling precise
coding for clinical and administrative purposes.
The alphanumeric structure of ICD-10-CM codes can range from three to seven characters. The first
character is always a letter, indicating the code chapter or category, followed by numeric characters that
define the condition’s category (Ex. J96). Additional characters provide specificity, such as severity,
anatomical site, or episode of care. Let's look at the medical code explanation below:
J96.01XA – Acute respiratory failure with hypoxia, initial encounter:
• J – The first character places the code in Chapter 10, which addresses Diseases of the Respiratory
System.
• 96 – The second and third characters specify the condition category, which is Respiratory failure.
• 0 – The fourth character identifies that the respiratory failure is acute.
• 1 – The fifth character indicates the specific type, in this case, acute respiratory failure with hypoxia
(low oxygen levels).
• X – A placeholder used when there are 7 characters, and no sixth character is needed
• A – The seventh character is the encounter extension. Here, "A" indicates this is the initial encounter
for the condition.
ICD-10-CM Terminology and Conventions
On top of being well-versed with knowledge of basic human anatomy, understanding ICD-10-CM terminology
and conventions is also crucial for accurate and consistent coding. There are key terms that coding
professionals should become familiar with to make sure that they are coding to the highest level of accuracy
possible.
Even when there is a lack of information, ICD-10-CM has a classification system for these situations. For
example, NOS (Not Otherwise Specified) is used when documentation is insufficient for a more specific code.
Contrast this with NEC (Not Elsewhere Classified) which indicates that a specific code for the condition is
unavailable. While the terms may sound similar, they are different and can impact data analysis and
reimbursement.
ICD-10-CM coding conventions can also provide vital information that will lead you to other information
throughout the coding manual. The term "Includes notes" provides examples of conditions within a category,
while "Excludes notes" clarify exclusions. "Excludes1" indicates conditions that cannot be coded together and
"Excludes2" allows separate coding for excluded conditions.
These are just a few coding guidelines that help clarify diagnoses and specificity to medical encounters.
These conventions guide coders in navigating the ICD-10-CM manual and ensure clarity and accuracy in
coding.
Chapter-Specific Guidelines
Chapter-specific guidelines in the ICD-10-CM manual provide additional instructions for coding based on a
specific body system or condition type. In Chapter 10, which covers diseases of the respiratory system,
combination codes capture conditions like acute respiratory failure with pneumonia. Respiratory conditions
caused by external agents require sequencing, with the respiratory condition coded first, and underlying or
additional conditions, followed by the external cause. Let's dissect this principle through an example:
A patient is admitted with acute respiratory failure due to pneumonia caused by aspiration of food particles.
There are three diagnostic codes needed for this situation coded in this sequence: J96.00, J69.0,
W778.1XXA.
• J96.00 – Acute respiratory failure, unspecified whether with hypoxia or hypercapnia (the respiratory
condition). Coded first because it is the primary issue being treated.
HTH 2305, Health Information Documentation Management 3
UNIT x STUDY GUIDE
Title
• J69.0 – Pneumonitis due to inhalation of food and vomit (the specific type of pneumonia caused by
aspiration), coded second to provide additional specificity about the underlying condition causing the
respiratory failure.
• W78.1XXA – Inhalation of food causing other injury, initial encounter (the external cause), coded last
to describe the event that led to the aspiration pneumonia.
Chapter 18 focuses on symptoms, signs, and abnormal clinical and laboratory findings, often using symptoms
as secondary codes when a definitive diagnosis is established. If no definitive diagnosis is reached, signs and
symptoms can serve as the primary reason for the encounter.
Chapter 21 covers factors influencing health status and contact with health services, including codes for
preventive services like screenings and vaccinations, as well as status codes indicating implants, prosthetics,
or chronic conditions that influence care.
Chapter 22 includes Codes for Special Purposes (U00–U85), which cover a range of supplementary
classifications, such as diseases of uncertain etiology, and emergency use codes. These codes are often
used for new or emerging diseases and conditions requiring immediate classification (e.g. code U07.1 for
COVID-19).
These are just a few of the chapter specific guidelines that are found throughout the ICD-10-CM coding
manual. At the beginning of each chapter in the manual, you will find special information regarding the coding
guidelines and processes specific to that chapter. Following these special guidelines will ensure that the
medical coding is accurate and will lead to proper treatment of the patient's diagnosis.
Medical Necessity
Medical necessity requires that healthcare services provided to patients are both reasonable and necessary
for the treatment of that patient’s condition. Payers, such as Medicare and private insurers, use diagnostic
codes to evaluate whether services meet this standard or not. Accurate coding ensures that healthcare
providers receive appropriate reimbursement while minimizing the risk of audits and denied claims. Thorough
documentation of the patient’s condition can support this documentation and align with payer and medical
policies.
The 2024 Improper Payments Fact Sheet, released by The Centers for Medicare and Medicaid Services,
stated that most Medicare fee-for-service improper payments were due to either insufficient documentation or
documentation that did not demonstrate medical necessity (CMS, 2024). According to the article, many of the
improper payments that CMS discovered could have been easily avoided through improved compliance, as
human error was the catalyst for many of these payment errors.
Primary Diagnosis vs. Principal Diagnosis
It is essential to understand the distinction between principal and primary diagnoses. The principal diagnosis
is the condition identified after study to be chiefly responsible for a patient’s admission to a hospital. For
example, a patient admitted with chest pain who is diagnosed with acute myocardial infarction would have
acute myocardial infarction as the principal diagnosis.
In contrast, the primary diagnosis refers to the main condition treated or evaluated during an outpatient
encounter, such as diabetes mellitus for a patient visiting a clinic for diabetes management. Confusing the
inpatient and outpatient settings can result in a coding error when it comes to primary vs. principal diagnoses.
Remember, primary diagnosis is for outpatient settings and principal diagnoses are for inpatient settings.
Accurate differentiation between these terms can assist with timely reimbursement structures and precise
reporting for quality metrics and research.
Best Practices
To ensure accuracy and compliance in diagnostic coding, best practices include thoroughly reviewing
documentation to make sure it captures relevant details such as severity, site, and laterality. Coders should
follow the official ICD-10-CM guidelines and stay informed about annual updates to the coding system.
HTH 2305, Health Information Documentation Management 4

Title
Collaboration with providers is crucial for clarifying ambiguous or incomplete documentation. Leveraging
technology, such as coding software and electronic health record (EHR) systems, can enhance accuracy and
efficiency.
Conclusion
These practices optimize reimbursement and contribute to improved patient care and robust healthcare data.
Diagnostic coding, particularly with the ICD-10-CM system, is fundamental to modern healthcare operations.
By mastering its structure, conventions, and guidelines, coders play a vital role in ensuring accurate and
compliant documentation of patient conditions. Through continued education and collaboration with providers,
coders can adapt to the challenges of the healthcare industry while upholding the highest standards of
integrity and accuracy.

Chapter-specific guidelines in the ICD-10-CM manual provide additional instructions for coding based on a
specific body system or condition type. In Chapter 10, which covers diseases of the respiratory system,
combination codes capture conditions like acute respiratory failure with pneumonia. Respiratory conditions
caused by external agents require sequencing, with the respiratory condition coded first, and underlying or
additional conditions, followed by the external cause. Let's dissect this principle through an example:
A patient is admitted with acute respiratory failure due to pneumonia caused by aspiration of food particles.
There are three diagnostic codes needed for this situation coded in this sequence: J96.00, J69.0,
W778.1XXA.
• J96.00 – Acute respiratory failure, unspecified whether with hypoxia or hypercapnia (the respiratory
condition). Coded first because it is the primary issue being treated.
HTH 2305, Health Information Documentation Management 3
UNIT x STUDY GUIDE
Title
• J69.0 – Pneumonitis due to inhalation of food and vomit (the specific type of pneumonia caused by
aspiration), coded second to provide additional specificity about the underlying condition causing the
respiratory failure.
• W78.1XXA – Inhalation of food causing other injury, initial encounter (the external cause), coded last
to describe the event that led to the aspiration pneumonia.
Chapter 18 focuses on symptoms, signs, and abnormal clinical and laboratory findings, often using symptoms
as secondary codes when a definitive diagnosis is established. If no definitive diagnosis is reached, signs and
symptoms can serve as the primary reason for the encounter.
Chapter 21 covers factors influencing health status and contact with health services, including codes for
preventive services like screenings and vaccinations, as well as status codes indicating implants, prosthetics,
or chronic conditions that influence care.
Chapter 22 includes Codes for Special Purposes (U00–U85), which cover a range of supplementary
classifications, such as diseases of uncertain etiology, and emergency use codes. These codes are often
used for new or emerging diseases and conditions requiring immediate classification (e.g. code U07.1 for
COVID-19).
These are just a few of the chapter specific guidelines that are found throughout the ICD-10-CM coding
manual. At the beginning of each chapter in the manual, you will find special information regarding the coding
guidelines and processes specific to that chapter. Following these special guidelines will ensure that the
medical coding is accurate and will lead to proper treatment of the patient's diagnosis.
Medical Necessity
Medical necessity requires that healthcare services provided to patients are both reasonable and necessary
for the treatment of that patient’s condition. Payers, such as Medicare and private insurers, use diagnostic
codes to evaluate whether services meet this standard or not. Accurate coding ensures that healthcare
providers receive appropriate reimbursement while minimizing the risk of audits and denied claims. Thorough
documentation of the patient’s condition can support this documentation and align with payer and medical
policies.
The 2024 Improper Payments Fact Sheet, released by The Centers for Medicare and Medicaid Services,
stated that most Medicare fee-for-service improper payments were due to either insufficient documentation or
documentation that did not demonstrate medical necessity (CMS, 2024). According to the article, many of the
improper payments that CMS discovered could have been easily avoided through improved compliance, as
human error was the catalyst for many of these payment errors.
Primary Diagnosis vs. Principal Diagnosis
It is essential to understand the distinction between principal and primary diagnoses. The principal diagnosis
is the condition identified after study to be chiefly responsible for a patient’s admission to a hospital. For
example, a patient admitted with chest pain who is diagnosed with acute myocardial infarction would have
acute myocardial infarction as the principal diagnosis.
In contrast, the primary diagnosis refers to the main condition treated or evaluated during an outpatient
encounter, such as diabetes mellitus for a patient visiting a clinic for diabetes management. Confusing the
inpatient and outpatient settings can result in a coding error when it comes to primary vs. principal diagnoses.
Remember, primary diagnosis is for outpatient settings and principal diagnoses are for inpatient settings.
Accurate differentiation between these terms can assist with timely reimbursement structures and precise
reporting for quality metrics and research.
Best Practices
To ensure accuracy and compliance in diagnostic coding, best practices include thoroughly reviewing
documentation to make sure it captures relevant details such as severity, site, and laterality. Coders should
follow the official ICD-10-CM guidelines and stay informed about annual updates to the coding system.

Collaboration with providers is crucial for clarifying ambiguous or incomplete documentation. Leveraging
technology, such as coding software and electronic health record (EHR) systems, can enhance accuracy and
efficiency.
Conclusion
These practices optimize reimbursement and contribute to improved patient care and robust healthcare data.
Diagnostic coding, particularly with the ICD-10-CM system, is fundamental to modern healthcare operations.
By mastering its structure, conventions, and guidelines, coders play a vital role in ensuring accurate and
compliant documentation of patient conditions. Through continued education and collaboration with providers,
coders can adapt to the challenges of the healthcare industry while upholding the highest standards of
integrity and accuracy.

• Your initial post should be at least 200 words in length.
Post 3: Response post to a second classmate or the instructor’s follow-up question is due by the end of day on Tuesday.
You recently helped your patient review a denied insurance claim for a routine diagnostic test. The insurance company stated the service was not medically necessary, even though the test was ordered by their doctor to monitor a chronic condition. This experience left you questioning how insurers determine what is "necessary" and why claims for essential care can be denied in some cases.
In your post, share your thoughts on how medical coders and healthcare providers can work together to minimize claim denials based on medical necessity. What steps can be taken to ensure that documentation and coding align with payer policies? Have you or someone you know faced a similar issue with insurance coverage? How would you address these situations in your future healthcare role?

Medical coders and healthcare providers play a crucial role in ensuring that insurance claims are approved, especially when it comes to proving medical necessity. From my perspective, strong collaboration between these two groups is essential to minimize claim denials. Providers need to clearly document the patient’s condition, symptoms, and the rationale for ordering specific tests or treatments. Coders, on the other hand, must accurately translate this information into codes that reflect the true nature of the care provided and match payer requirements.
One important step is ongoing education for both providers and coders about current insurance policies and guidelines. Regular training sessions can help everyone stay updated on what insurers consider medically necessary and how to properly document and code those services. Additionally, using checklists or templates during documentation can ensure all required details are included, such as the diagnosis, relevant history, and the reason for the test or procedure.
I have seen family members struggle with denied claims for tests their doctors said were needed. In those cases, appeals were often successful when additional documentation was provided, showing why the service was essential. If I encounter similar situations in my future healthcare role, I would advocate for thorough documentation from the start and work closely with coders to make sure everything aligns with payer policies. I would also educate patients about the importance of clear communication with their providers regarding their health needs and insurance coverage. Ultimately, teamwork and attention to detail are key to reducing unnecessary denials and ensuring patients get the care they need.
**Response 2: Robie OgnibeneTop of Form**
Insurance denials based on “medical necessity” can be really confusing, especially when a doctor clearly ordered something for a valid reason. After helping a patient review a denied claim for a routine test, I started wondering how insurers decide what counts as necessary in the first place. It made me realize how important it is for medical coders and healthcare providers to work closely together to prevent these kinds of issues.
One big way to reduce denials is making sure the documentation fully explains why the test or procedure was needed. Providers have to clearly describe the patient’s symptoms, history, and diagnosis so coders can match the correct ICD-10 and CPT codes. Coders also play a major role by checking payer policies, catching missing details, and helping providers understand what insurance companies expect. Even small gaps in documentation can lead to a denial, so communication between the coding and clinical teams is key.
I’ve seen people I know run into the same problem—insurance denying something that their doctor felt was necessary. Most of the time, it came down to how the information was documented. In my future healthcare role, I would try to address these issues early by double-checking payer requirements, making sure charts are complete, and helping patients appeal denials when needed. At the end of the day, patients deserve care without unnecessary obstacles.

Unit Lesson
Lesson: Diagnostic Medical Coding (ULOs 2.2 and 3.1)
Introduction
Diagnostic coding is a critical aspect of medical billing and healthcare documentation, ensuring accurate
representation of a patient's diagnosis for clinical as well as administrative purposes.
Consider a scenario where a patient presents with shortness of breath and fever. Initially, the diagnosis might
be documented as pneumonia. However, modern diagnostic coding enables the addition of specificity, such
as "J18.9" for unspecified pneumonia or "J15.9" for bacterial pneumonia, depending on lab results. This
precise coding ensures the patient’s treatment aligns with their exact condition and allows for proper
insurance reimbursement. This unit will cover the basics of diagnostic coding, the International Classification
of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) system, and medical necessity. First, let's
discuss the importance of understanding human anatomy and physiology when it comes to medical coding.
Human Anatomy and Physiology
Understanding human anatomy is an essential skill for medical coders as it helps them identify and apply
codes based on the location and nature of medical conditions. As outlined in the previous example,
understanding the anatomical distinctions between the upper and lower respiratory tract is critical when
coding for conditions like bronchitis versus pneumonia.
This is one reason why human anatomy and physiology should be a course that health information
professionals take early in their educational journey. A solid grasp of anatomy helps coders interpret clinical
documentation effectively, resulting in assigned codes that accurately reflect the patient's diagnosis and
treatment. This leads to improved quality of care and more efficient reimbursement processes.
International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM)
Diagnostic coding is governed by the International Classification of Diseases, 10th Revision, Clinical
Modification (ICD-10-CM). This standardized system, developed by the World Health Organization (WHO)

Title
and modified for use in the United States, is used to document and track diseases and other health
conditions. With over 70,000 codes, the ICD-10-CM system offers a high level of detail, enabling precise
coding for clinical and administrative purposes.
The alphanumeric structure of ICD-10-CM codes can range from three to seven characters. The first
character is always a letter, indicating the code chapter or category, followed by numeric characters that
define the condition’s category (Ex. J96). Additional characters provide specificity, such as severity,
anatomical site, or episode of care. Let's look at the medical code explanation below:
J96.01XA – Acute respiratory failure with hypoxia, initial encounter:
• J – The first character places the code in Chapter 10, which addresses Diseases of the Respiratory
System.
• 96 – The second and third characters specify the condition category, which is Respiratory failure.
• 0 – The fourth character identifies that the respiratory failure is acute.
• 1 – The fifth character indicates the specific type, in this case, acute respiratory failure with hypoxia
(low oxygen levels).
• X – A placeholder used when there are 7 characters, and no sixth character is needed
• A – The seventh character is the encounter extension. Here, "A" indicates this is the initial encounter
for the condition.
ICD-10-CM Terminology and Conventions
On top of being well-versed with knowledge of basic human anatomy, understanding ICD-10-CM terminology
and conventions is also crucial for accurate and consistent coding. There are key terms that coding
professionals should become familiar with to make sure that they are coding to the highest level of accuracy
possible.
Even when there is a lack of information, ICD-10-CM has a classification system for these situations. For
example, NOS (Not Otherwise Specified) is used when documentation is insufficient for a more specific code.
Contrast this with NEC (Not Elsewhere Classified) which indicates that a specific code for the condition is
unavailable. While the terms may sound similar, they are different and can impact data analysis and
reimbursement.
ICD-10-CM coding conventions can also provide vital information that will lead you to other information
throughout the coding manual. The term "Includes notes" provides examples of conditions within a category,
while "Excludes notes" clarify exclusions. "Excludes1" indicates conditions that cannot be coded together and
"Excludes2" allows separate coding for excluded conditions.
These are just a few coding guidelines that help clarify diagnoses and specificity to medical encounters.
These conventions guide coders in navigating the ICD-10-CM manual and ensure clarity and accuracy in
coding.
Chapter-Specific Guidelines
Chapter-specific guidelines in the ICD-10-CM manual provide additional instructions for coding based on a
specific body system or condition type. In Chapter 10, which covers diseases of the respiratory system,
combination codes capture conditions like acute respiratory failure with pneumonia. Respiratory conditions
caused by external agents require sequencing, with the respiratory condition coded first, and underlying or
additional conditions, followed by the external cause. Let's dissect this principle through an example:
A patient is admitted with acute respiratory failure due to pneumonia caused by aspiration of food particles.
There are three diagnostic codes needed for this situation coded in this sequence: J96.00, J69.0,
W778.1XXA.
• J96.00 – Acute respiratory failure, unspecified whether with hypoxia or hypercapnia (the respiratory
condition). Coded first because it is the primary issue being treated.

• J69.0 – Pneumonitis due to inhalation of food and vomit (the specific type of pneumonia caused by
aspiration), coded second to provide additional specificity about the underlying condition causing the
respiratory failure.
• W78.1XXA – Inhalation of food causing other injury, initial encounter (the external cause), coded last
to describe the event that led to the aspiration pneumonia.
Chapter 18 focuses on symptoms, signs, and abnormal clinical and laboratory findings, often using symptoms
as secondary codes when a definitive diagnosis is established. If no definitive diagnosis is reached, signs and
symptoms can serve as the primary reason for the encounter.
Chapter 21 covers factors influencing health status and contact with health services, including codes for
preventive services like screenings and vaccinations, as well as status codes indicating implants, prosthetics,
or chronic conditions that influence care.
Chapter 22 includes Codes for Special Purposes (U00–U85), which cover a range of supplementary
classifications, such as diseases of uncertain etiology, and emergency use codes. These codes are often
used for new or emerging diseases and conditions requiring immediate classification (e.g. code U07.1 for
COVID-19).
These are just a few of the chapter specific guidelines that are found throughout the ICD-10-CM coding
manual. At the beginning of each chapter in the manual, you will find special information regarding the coding
guidelines and processes specific to that chapter. Following these special guidelines will ensure that the
medical coding is accurate and will lead to proper treatment of the patient's diagnosis.
Medical Necessity
Medical necessity requires that healthcare services provided to patients are both reasonable and necessary
for the treatment of that patient’s condition. Payers, such as Medicare and private insurers, use diagnostic
codes to evaluate whether services meet this standard or not. Accurate coding ensures that healthcare
providers receive appropriate reimbursement while minimizing the risk of audits and denied claims. Thorough
documentation of the patient’s condition can support this documentation and align with payer and medical
policies.
The 2024 Improper Payments Fact Sheet, released by The Centers for Medicare and Medicaid Services,
stated that most Medicare fee-for-service improper payments were due to either insufficient documentation or
documentation that did not demonstrate medical necessity (CMS, 2024). According to the article, many of the
improper payments that CMS discovered could have been easily avoided through improved compliance, as
human error was the catalyst for many of these payment errors.

acute myocardial infarction as the principal diagnosis.
In contrast, the primary diagnosis refers to the main condition treated or evaluated during an outpatient
encounter, such as diabetes mellitus for a patient visiting a clinic for diabetes management. Confusing the
inpatient and outpatient settings can result in a coding error when it comes to primary vs. principal diagnoses.
Remember, primary diagnosis is for outpatient settings and principal diagnoses are for inpatient settings.
Accurate differentiation between these terms can assist with timely reimbursement structures and precise
