If a patient presents with signs and symptoms suggestive of a disorder but lacks a confirmed diagnosis, what coding approach is appropriate?

• A. Code the signs and symptoms
• B. Code the most likely diagnosis
• C. Do not code anything until diagnosed
• D. Code an unspecified disorder

Answer: (A)

When a patient presents with signs and symptoms but no confirmed diagnosis, code the signs and symptoms. This mirrors what is actually documented and reflects the patient’s current presentation, supporting ongoing evaluation and testing without implying a disease that isn’t yet proven. Coding the most likely diagnosis would rely on an assumption, which isn’t appropriate when the diagnosis isn’t confirmed. Waiting to code until a diagnosis is established would leave the encounter underrepresented. If specific symptoms are described, use the corresponding symptom codes (for example, chest pain, fever, cough). If the clinician is observing for a suspected condition, you can add an encounter-for-observation code as appropriate, but the primary codes should be the documented signs and symptoms.
