How many times can each unique ICD-10-CM diagnosis code be reported per encounter?

Each unique ICD-10-CM diagnosis code can be reported once per encounter. This is a key guideline in coding as it ensures that medical records reflect the patient's conditions accurately without unnecessary repetition. The intent of this guideline is to maintain clarity and consistency in the medical documentation, allowing healthcare providers and payers to understand the patient's diagnoses without confusion.

For example, if a patient has multiple diagnoses during a single visit, each distinct diagnosis should be coded accurately, but each specific code only needs to be listed once. This approach helps in streamlining billing processes and minimizing potential errors or audits related to coded information.

Other possible responses suggest either multiple reporting of the same diagnosis code or restrictions that do not align with the principles of proper coding practices. Thus, the accurate understanding of how many times a code can be reported is essential for efficient and compliant medical coding.
