In ICD-10-CM coding, where is a chronic condition like essential hypertension typically documented?

• A. In the problem list with a chronic diagnosis and specifier
• B. In the revenue code
• C. In the discharge summary only
• D. In the medication list only

Answer: (A)

Chronic conditions like essential hypertension are documented in the patient’s problem list. This keeps a persistent, accessible record of ongoing diagnoses and any needed specifiers (for example, essential hypertension, controlled or uncontrolled). Having hypertension in the problem list ensures the correct ICD-10-CM code is linked to the patient’s active problems across encounters. The other options don’t serve as the primary source for coding: revenue codes are billing categories, discharge summaries are communication documents of care at discharge, and the medication list shows medications rather than diagnoses. So the problem list with the chronic diagnosis and specifier is the appropriate place.
