Chiropractic billing: spinal regions, active treatment, and maintenance care
Chiropractic manipulative treatment is coded by the number of spinal regions treated, with a separate code for extraspinal regions, so the regions documented in the note directly determine the code. Payers know that region counts drift upward over a treatment course, and a note that lists the same regions every visit without changing findings invites a records request. The examination documenting pain, asymmetry, range-of-motion loss, and tissue tone changes is what substantiates the region count.
For Medicare, the harder issue is the line between active treatment and maintenance care. Medicare covers manual manipulation of the spine to correct a subluxation only, does not pay for the examination or therapies chiropractors commonly provide, and requires the active-treatment modifier on covered manipulation. Once care becomes maintenance, it is not covered and the patient must be notified in advance for the practice to collect. We keep treatment plans framed around measurable functional goals, apply the active-treatment modifier only when the record supports it, and issue advance notices before maintenance visits rather than after.
Coding and documentation focus
- ✓Spinal region counts — Manipulation is coded by regions treated, so the documented examination findings per region have to support the code billed.
- ✓Active treatment modifier — Medicare requires the active-treatment modifier on covered manipulation, and its absence turns the claim into a non-covered service.
- ✓Maintenance care and advance notice — Maintenance therapy is excluded from coverage, so an advance beneficiary notice must be signed before those visits to bill the patient.
- ✓Therapies and examinations — Medicare does not cover chiropractic examinations or physical therapy modalities, which have to be handled as patient responsibility from the start.
Denials we prevent on these claims
- ✓Active-treatment modifier missing from covered manipulation — added through our specialty scrub.
- ✓Region count unsupported by the documented examination — returned to the provider pre-bill.
- ✓Maintenance care billed without a signed advance notice — flagged so the visit stays collectible.
- ✓Non-covered therapies submitted to Medicare as covered — routed to patient responsibility correctly.
Frequently asked questions
What does Medicare actually cover for chiropractic care?
Only manual manipulation of the spine to correct a subluxation, and only while the care is active treatment expected to improve the condition. Examinations, x-rays taken by the chiropractor, and therapy modalities are not covered Medicare benefits regardless of medical necessity.
How do we bill maintenance visits?
As patient responsibility, with an advance beneficiary notice signed before the service and the appropriate non-covered modifier on the claim. Doing this before the visit is what preserves your right to collect; doing it after a denial usually does not.
