Exacerbation of a pre-existing chronic condition (long re-evaluation) corresponds to which CPT code?

• A. 99213
• B. 99212
• C. 99214
• D. 99203

Answer: (A)

When assessing an exacerbation of a pre-existing chronic condition in someone who is an established patient, the coding decision hinges on the amount of history, the exam performed, and the medical decision making (MDM) needed. A long re-evaluation due to a chronic flare typically involves a focused history about the current symptoms and prior status, a targeted exam focusing on the acute change, and MDM that is straightforward to low-moderate in complexity. This combination aligns with a level 3 established patient visit. It’s not a new patient, so codes for new patients aren’t appropriate, and it’s not high enough in complexity to justify a higher level unless documentation shows more extensive problems or higher-risk management. Therefore, the best match is the level 3 established patient visit code.
