What CPT code would be appropriate for a preventive medicine service for an established patient?

The appropriate CPT code for a preventive medicine service for an established patient is 99395. This code specifically pertains to periodic comprehensive preventive medicine evaluations and management for an established patient aged 18 or older, providing a thorough assessment of health status, counseling, and updates to preventive measures.

Each of the other codes represents preventive services but applies to different age groups or scenarios. For instance, code 99394 is intended for established patients aged 12 to 17, while 99396 is applicable for established patients aged 40 to 64. Meanwhile, code 99397 is used for preventive services for patients aged 65 and older. Selecting 99395 appropriately identifies the service for an established adult patient in the age group that the code covers, ensuring accurate documentation and billing for the preventive care provided.
