The Medicine section of the CPT code set includes a wide variety of diagnostic, therapeutic, preventive, and management services that healthcare providers perform every day. Unlike the Surgery, Radiology, or Pathology sections, the Medicine section covers services across many medical specialties, making it one of the most diverse parts of the CPT codebook.
Physicians, nurse practitioners, physician assistants, therapists, pharmacists, chiropractors, psychologists, and many other healthcare professionals report Medicine CPT codes when they provide specialized medical services outside the Evaluation and Management (E/M) section.
The Medicine CPT code section spans 90281 through 99607. It includes immunizations, psychiatry, dialysis, cardiology, pulmonary medicine, rehabilitation, nutrition therapy, neurology, allergy services, acupuncture, medication therapy management, and many other clinical services.
This guide explains how the Medicine CPT section is organized, what each code category includes, documentation requirements, billing considerations, and common coding challenges.
