Elite Bill Care — Your Success, Our Commitment

Chiropractic Billing

AT-modifier discipline, Medicare's subluxation rules and commercial visit limits — chiropractic billing without the usual denial churn.

Chiropractic has the narrowest coverage rules in outpatient care: Medicare pays for one thing (manual manipulation to correct subluxation) under strict documentation, while commercial plans add their own visit caps and review triggers. Elite Bill Care's chiropractic billing is built around those realities.

Chiropractic billing specifics

  • CMT codes — 98940–98942 by regions manipulated, plus 98943 for extraspinal, each needing documentation that matches the regions billed.
  • The AT modifier — declares active/corrective treatment; without it Medicare treats the claim as maintenance and denies. Maintenance care is not a Medicare benefit, and billing it as active is a compliance problem, not a strategy.
  • Subluxation documentation — Medicare requires subluxation demonstrated by X-ray or physical examination (PART criteria), with treatment goals and progress recorded.
  • Commercial plans — visit limits, combined PT/chiro caps in some plans, and medical-necessity review after set visit counts; counted from the first visit via eligibility checks.
  • Adjunct services — therapies (97012, 97140, etc.) covered differently by plan and by Medicare (generally not covered when billed by chiropractors to Medicare) — billed only where the plan actually covers them for DCs.

How we run it

Every claim is checked for modifier and region consistency under coding support, active-vs-maintenance status is kept straight in documentation feedback, and denials are worked through denial management. See the full operation on our billing services page.

Frequently asked questions

Does Medicare cover chiropractic X-rays or therapy?

Medicare coverage for chiropractors is limited to manual spinal manipulation for subluxation; X-rays and therapies ordered or performed by a DC are not covered by Medicare. Commercial plans differ — we verify per plan.

Can you bill cash services alongside insurance care?

Yes — with clean separation: covered services billed to the plan, non-covered services handled under your office's patient-payment policies and applicable rules, never mixed on a claim.
