Frequently asked questions

CPT code 98940 represents chiropractic manipulative treatment (CMT) for 1–2 spinal regions, including manual adjustments to correct spinal subluxations in areas such as cervical, thoracic, lumbar, sacral, or pelvic regions. It requires documentation of medical necessity and is often billed with the AT modifier to indicate active treatment for acute/chronic conditions.

There is no standalone CPT code for a chiropractic exam; initial exams are typically billed using Evaluation and Management (E/M) codes (e.g., 99202–99205 for new patients). Chiropractic-specific codes (98940–98943) cover manipulative treatment only, but the exam must be documented separately, often with modifier 25 if performed on the same day as CMT.

98941 applies to spinal manipulation of 3–4 regions (e.g., cervical, lumbar), while 98943 covers extraspinal manipulation (e.g., shoulders, knees, ribs) for 1+ regions. Medicare does not reimburse 98943.
