The Official ICD Coding Guidelines state that a condition must be present at the time of the encounter, affect patient care or management and be clearly documented in order to be coded as a diagnosis. Physicians must accurately document each patient diagnosis and the diagnosis MUST be based on clinical medical record documentation from a face-to-face encounter. This simply means that diagnoses cannot be wholly determined from test results and a patient’s past medical history.

A well-documented progress note would include the HPI, ROS, physical exam and show the medical decision-making process. Each diagnosis must be documented in an assessment and care plan and each diagnosis must show that the provider is Monitoring, Evaluating, Assessing/addressing or Treating the condition: 

M.E.A.T is an acronym for:

M: Monitor—signs, symptoms, disease progression, disease regression

E: Evaluate—test results, medication effectiveness, response to treatment

A: Assess/Address—ordering tests, discussion, review records, counseling

T: Treat—medications, therapies, other modalities

These four factors help providers establish the presence of a diagnosis during an encounter and ensure proper documentation.

Simply listing every diagnosis in the medical record does not support a reported HCC code* and is unacceptable according to CMS. An acceptable problem list must show evaluation and treatment for each condition that relates to an ICD code.

Examples of supported documentation:

Hypertension (I10) remains stable, will continue with Losartan 100 mg daily.

Depression recurrent moderate (F33.1) patient has not noticed improvement on current medication, will increase Zoloft from 50mg to 100mg.

CMS focuses on these diagnoses to demonstrate the need for higher reimbursement rates for patients who have more serious conditions or problems to manage. If the diagnosis on the claim is not accurate or complete, this would indicate that the provider did much less work (medical decision making, evaluation, and management) than actually performed, leading to much lower reimbursement.

However, not only should providers show evaluation and treatment for all conditions assessed at the time of the encounter, but they should also ensure that this information is documented. It is acceptable to include “history of” conditions if it affects the current treatment plan. There are multiple instances where these conditions are addressed and treated, but do not make it to the Assessment and Plan. For example: If there is a history of breast cancer (Z85.3) and the patient is ordered a mammogram, be sure to include this information under the A/P.

Following these standard practices will ensure accurate documentation, quality patient care and an improvement in data integrity.

*HCC DEFINITION

Risk Adjustment and Hierarchical Condition Category (HCC) coding is a payment model mandated by the Centers for Medicare and Medicaid Services (CMS) in 1997. Implemented in 2003, this model identifies individuals with serious or chronic illness and assigns a risk factor score to the person based upon a combination of the individual’s health conditions and demographic details. The individual’s health conditions are identified via International Classification of Diseases (ICD –10) diagnoses that are submitted by providers on incoming claims
