What order do the cpt 99212 and 99396 go in?

CPT code 99212 is used for an established patient office visit that requires a low level of medical decision-making, while CPT code 99396 is for a periodic comprehensive preventive medicine evaluation and management for an established patient. When documenting services, the order typically follows the nature of the visit, so if both codes are applicable, you would list the preventive visit (99396) first, followed by the problem-focused visit (99212), provided both services were performed during the same encounter. However, the specific order may depend on the context of billing and payer guidelines.
