Can 99396 be billed with 99215?

Yes, 99396 (preventive medicine visit for an established patient) can be billed with 99215 (office or other outpatient visit for an established patient, typically requiring a medically appropriate history and/or examination) if both services are distinct and necessary. However, documentation must clearly support the medical necessity of both visits, and the use of modifiers may be required to indicate that the services are separate. It's important to check with specific payer guidelines, as policies can vary.
