Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 98940 covers

This service involves chiropractic adjustment of one or two of the five spinal regions: cervical, thoracic, lumbar, sacral, and pelvic. A patient with low back pain might receive treatment in the lumbar and pelvic regions; a patient with neck pain might receive treatment in the cervical region. Doctors of chiropractic typically perform the service in an office. For Medicare coverage of care furnished by a chiropractor, the manipulation must be directed at correcting a spinal subluxation.

Count distinct regions adjusted, not individual vertebral segments; manipulation of three or four regions is reported with 98941. Medicare requires evidence of subluxation by x-ray or physical examination. Examination findings use PART: pain or tenderness, asymmetry or misalignment, range-of-motion abnormality, and tissue or tone change. Document the regions treated, findings, treatment plan, and progress; append modifier AT for active or corrective treatment, not maintenance care. The 0-day global period includes same-day preoperative and postoperative care. Modifier 50 is inappropriate. CMS permits assistant-at-surgery payment only with documented medical necessity; co-surgeons and team surgery are not permitted.
