Chiropractic denials: spinal manipulation, active care, and maintenance
Medicare covers exactly one chiropractic service, and the line between active treatment and maintenance care decides whether it gets paid.
The rules behind the denials
- What Medicare actually covers
- Manual manipulation of the spine to correct a subluxation. That is the entire covered benefit. Examinations, imaging ordered by the chiropractor, and other services in the visit are not separately covered under it.
- Active treatment versus maintenance
- Claims must indicate that the manipulation was active, corrective treatment rather than maintenance. Maintenance care — services intended to sustain a level of function rather than improve it — is not a covered benefit, however clinically reasonable it may be.
- Documented subluxation
- The record must establish the subluxation the manipulation is correcting, demonstrated by physical examination findings or imaging. Without it, there is nothing on the record for the manipulation to be treating.
Why these denials fire
- 01The claim did not carry the active-treatment indication, so it was read as maintenance and denied without clinical review.
- 02The record documents the treatment but not the subluxation being corrected.
- 03Notes describe ongoing care without documenting improvement, so the episode reads as maintenance.
- 04Services beyond spinal manipulation were billed to Medicare, which does not cover them under this benefit.
- 05The treatment plan lacks measurable goals, leaving no basis to distinguish active care from maintenance.
Documentation that wins
- Examination findings establishing the subluxation and the spinal region involved.
- An initial evaluation recording the presenting complaint, its mechanism, and its functional impact.
- A treatment plan with measurable goals and an expected duration.
- Objective findings repeated across visits — the change over time is the evidence of active treatment.
- A clear statement of the functional improvement being sought, distinguishing this episode from maintenance.
Arguments that work
- The record documents a subluxation and an active course of treatment directed at correcting it.
- Objective findings show functional improvement across the episode, which is inconsistent with maintenance care.
- The claim reflected active treatment and the denial rests on a claim-level indicator rather than the clinical record.
- The treatment plan sets measurable goals and a defined endpoint, not indefinite supportive care.
What Undeny will not do
Undeny does not advise which CPT code or modifier to use, or whether a given episode qualifies as active treatment. That determination belongs to the treating chiropractor and your coder, based on the record. Undeny argues the appeal from the documentation you already have.
Common questions
- Why was my chiropractic claim denied without any clinical review?
- Because the active-treatment indication was missing from the claim. Medicare reads a spinal manipulation claim without it as maintenance care, which is not a covered benefit, and denies it on that basis before anyone looks at the record.
- Is maintenance care ever payable by Medicare?
- No. Maintenance care is excluded regardless of how clinically appropriate it is. This is a benefit-design exclusion, not a judgment about the care — which is why appeals must show the episode was active treatment rather than argue that maintenance was worthwhile.
- How much scrutiny do chiropractic claims actually get?
- Considerable. An HHS Office of Inspector General audit found the large majority of Medicare payments for chiropractic services to be unallowable, driven substantially by maintenance care billed as active treatment. That history is why documentation of subluxation and measurable progress carries so much weight on appeal.

Upload the denial. Undeny reads it, drafts the appeal letter from the denial code and the record, and tracks the deadline until the money comes back.
Other specialties
- Physical therapyTwo Medicare rules drive most PT denials: how timed treatment converts into billable units, and what happens once a patient crosses the annual therapy threshold.
- Behavioral healthSession limits and concurrent review drive most behavioral health denials — and federal parity law gives you an argument that has nothing to do with coding.
- DermatologyMost dermatology denials come down to two documentation questions — whether the record establishes the procedure was medical rather than cosmetic, and whether a same-day visit stands on its own.
