Chiropractic Billing Services
A chiropractic practice is three practices billing side by side, and the fastest way to lose money is to run them as one. Medicare is the narrowest: it pays for manual manipulation of the spine to correct a subluxation and for nothing else the chiropractor does or orders — not the exam, not the x-ray, not the adjunctive therapy — and it pays by the spinal regions the note supports. Commercial plans are a second track, with annual visit allowances, functional-outcome requirements and their own bundling logic for same-day manual therapy. Personal injury, auto and workers' compensation are a third, running on statute, attorney liens and state fee schedules rather than on a contract and an EOB. What that costs is rarely one large denial. It is the active-treatment modifier missing from a Medicare claim, which turns a covered adjustment into maintenance therapy. It is a region count billed above what the note documents at the vertebral level. It is an exam sent to Medicare that was never covered, returning as a write-off rather than a patient balance. It is a visit past the plan's allowance that nobody was counting. We take that reconciliation off the front desk: each adjustment coded to the regions the note names, with the active-treatment modifier and PART findings behind it. We route what Medicare does not cover to the patient or the secondary before it ages, and keep a running visit count per member against that member's own plan allowance. Personal injury, auto and workers' compensation run with us as their own queue, with the state fee schedule and the lien release prepared ahead of disbursement.

What do chiropractic billing services cover?
We bill chiropractic practices across all three revenue tracks, and we keep them separate because their rules are. On Medicare, coverage is limited to manual manipulation of the spine to correct a subluxation: CMT is coded to the regions the note supports, the AT modifier marks active or corrective treatment, and a claim without AT is considered maintenance therapy and denied (Medicare Benefit Policy Manual, Chapter 15, §240.1.3, read 17 September 2026). Subluxation is demonstrated by x-ray or by physical examination, and the exam route needs two of the four PART findings with asymmetry or misalignment or range-of-motion abnormality among them, at a named vertebral level (§§240.1.2 and 240.1.4). On commercial plans we track visit allowances and file the functional outcome scores the plan requires before its re-authorization checkpoint. On personal injury, auto and workers' compensation we run the statutory benefit, the lien and the state fee schedule as their own workflow.
- AT modifier on every Medicare active-care claim, with PART findings named to the vertebral level rather than "cervical subluxation"
- Region count on the claim matched to the regions the note documents — 98940 one to two, 98941 three to four, 98942 five
- 98943 extraspinal manipulation and every chiropractor-ordered x-ray, exam or modality routed to the patient or the secondary, because Medicare does not cover them
- 97140 separated from same-day CMT with modifier 59 only when the manual therapy was performed on a different region
- Personal injury, auto and workers' comp run on their own track — PIP and medpay routing, attorney liens released before settlement disburses

Common Billing Friction in Chiropractic
AT modifier discipline and the active-versus-maintenance line
Medicare draws the line at whether treatment is still corrective. A chiropractor must place the AT modifier on the claim when providing active or corrective treatment for an acute or chronic subluxation, and CMS is explicit that a claim without AT will be considered maintenance therapy and denied. It is equally explicit the other way: the presence of AT does not by itself make a service reasonable and necessary, and contractors may still deny after review. Once the clinical status has remained stable for a condition without expectation of further objective improvement, continued manipulation is maintenance and is not covered — at which point the practice moves the patient to direct pay and, where an advance beneficiary notice is issued, adds the GA modifier (Medicare Benefit Policy Manual Pub 100-02 Chapter 15 §240.1.3, read 17 September 2026). There is no annual Medicare visit cap on chiropractic and no KX modifier requirement: the KX threshold belongs to outpatient therapy services under §1833(g) of the Social Security Act, and the therapy caps themselves were repealed by section 50202 of the Bipartisan Budget Act of 2018. What §240.1.5 actually sets is a treatment-parameter expectation — acute problems such as strains or sprains may require as much as three months of treatment, frequency should decline as improvement is obtained, and Medicare pays for no more than one treatment per day.
PART exam documentation and subluxation specificity
Since 1 January 2000 an x-ray has not been required to demonstrate subluxation; physical examination is the other route, and CMS sets the test precisely. The exam evaluates four things — pain or tenderness in terms of location, quality and intensity; asymmetry or misalignment identified at a sectional or segmental level; range of motion abnormality; and tissue or tone changes in contiguous or associated soft tissue — and two of those four are required, one of which must be asymmetry or misalignment or range of motion abnormality (Pub 100-02 Chapter 15 §240.1.2, read 17 September 2026). Separately, §240.1.4 requires the precise level of the subluxation to be specified: the exact bones (C5, C6) or an area that implies only certain bones (lumbosacral, sacroiliac). A note reading 'cervical subluxation' satisfies neither test. The initial visit also needs the history, the mechanism of trauma, symptoms that bear a direct relationship to the level cited, a primary diagnosis of subluxation at that level, and a treatment plan with recommended duration and frequency, specific goals and objective measures; subsequent visits need the change since the last visit and an evaluation of treatment effectiveness. Liability carriers contesting the duration of care pull the same documentation, so the standard is worth meeting once rather than twice.
Same-day manual therapy and the modifier 59 test
Manual therapy (CPT 97140) on the same date as CMT is bundled by default under NCCI edit logic — the presumption is that manual therapy applied to the same region was already part of the manipulation. Unbundling requires modifier 59 plus documentation that 97140 was performed on a separate body region, with its own timed treatment minutes recorded under the CPT timed-code rules. Rotator-cuff manual therapy on a visit whose CMT covered three spinal regions is the defensible case; the same region twice is not. Two traps sit next to it. Practices that append 59 to every visit without region differentiation create a pattern that reads as an audit finding rather than as revenue. And on Medicare, unattended electrical stimulation is not billed with CPT 97014 at all — that code carries status I, not valid for Medicare purposes, and Medicare uses G0283 instead — so a modifier argument about it never gets as far as the bundling question.
Personal injury, auto and workers' compensation as a separate workflow
These claims run on statute and on liens rather than on a fee schedule and an EOB, and the statute is state-specific. Florida is the clearest illustration and the one most often quoted wrongly. Under Fla. Stat. §627.736 (2025 edition, read 17 September 2026), personal injury protection provides a $10,000 limit in medical and disability benefits, medical benefits are 80 percent of reasonable expenses, and they are payable only if the injured person receives initial services and care within 14 days of the crash. A chiropractic physician licensed under chapter 460 may provide that initial care and may order follow-up care — but the determination that unlocks the full $10,000 is an emergency medical condition determination, and the statute limits who can make one to a physician under chapter 458 or 459, a dentist, a physician assistant or an advanced practice registered nurse. Without that determination, reimbursement is capped at $2,500. Massage therapy and acupuncture are excluded from PIP medical benefits outright. The insurer may also limit reimbursement to 80 percent of a schedule of maximum charges, which for most medical services is 200 percent of the Medicare Part B participating physician fee schedule. After PIP exhausts, the claim moves to the at-fault driver's bodily injury carrier and becomes a lien matter; workers' compensation adds state-board fee schedules and case-manager pre-authorization. Mishandled lien releases at settlement are the largest source of bad-debt write-offs in the specialty.
Visit allowances, functional outcomes and the re-authorization checkpoint
Commercial chiropractic benefits are commonly capped at an annual visit count, and many plans stop authorizing further care without functional outcome data — an Oswestry Disability Index, a Neck Disability Index or an equivalent instrument — filed on the plan's schedule. Both the allowance and the instrument are terms of the specific plan and product with their own effective date, so the number that applies to your patient is the one on that member's plan rather than a figure quoted from another carrier. The operational requirement is the same whatever the number: a running visit count per member per plan year, a provider alert before the threshold rather than after it, and the outcome score filed before the re-authorization checkpoint rather than in response to a denial. A patient at the cap needs an appeal with documented continued medical necessity, a move to cash pay, or a written notification before the next visit; practices that keep treating without that conversation absorb the visits and inherit a patient billing dispute.
Chiropractic-Specific Payer Issues We Watch For
Medicare
Issue: Covers only manual manipulation of the spine to correct a subluxation, billed as 98940, 98941 or 98942 with the AT modifier. Everything else a chiropractor performs or orders is excluded — exams, x-rays and adjunctive therapies — and extraspinal manipulation (98943) is non-covered as well
Our approach: We bill Medicare only the covered CMT codes with the AT modifier and the subluxation documentation behind them, and route every non-covered service to patient responsibility or the secondary before it becomes a write-off
UnitedHealthcare
Issue: Annual chiropractic visit allowances are set per plan and per product with their own effective date, and a claim past the allowance is denied without a separate notification to the practice
Our approach: We keep a running visit count per member against that member's own plan allowance and raise a provider alert before the threshold, so the continued-care conversation happens before the visit rather than after the denial
BCBS
Issue: Frequently bundles 97140 (manual therapy) with 98941 (CMT) when performed on the same date, denying manual therapy as inclusive of the manipulation
Our approach: We document manual therapy techniques as distinct from CMT with separate body regions, apply modifier 59, and include specific treatment time documentation
Cigna
Issue: Continued authorization beyond the initial allowance is conditioned on functional outcome data filed on the plan's own schedule, and care delivered while the score is outstanding is delivered at risk
Our approach: We build outcome-instrument collection into the visit workflow and file the score ahead of the re-authorization checkpoint the plan sets, rather than attaching it to an appeal afterwards
What We Handle
CMT region-count coding (98940 1–2, 98941 3–4, 98942 5 regions)
Region-by-region review of the note against the billed code, with the subluxation level named to the exact bones or to an area that implies only certain bones. CPT 98943 extraspinal manipulation billed to commercial and liability payers where the benefit allows it, and routed to patient responsibility on Medicare, where it is non-covered.
AT modifier discipline and Medicare LCD compliance
AT applied on every Medicare active-care claim with PART documentation tied to that visit and progress shown from visit to visit. Maintenance care converted to direct pay once further objective improvement is no longer expected, with an advance beneficiary notice and the GA modifier where one is issued.
Adjunctive therapy coding — 97140, 97110, 97012 and G0283
Manual therapy (97140), therapeutic exercise (97110) and mechanical traction (97012) billed with modifier 59 and separate-region documentation where the note supports it, and timed-code minutes captured under the CPT timed-code rules. Unattended electrical stimulation billed as G0283 on Medicare, because CPT 97014 is not valid for Medicare purposes.
Visit-count tracking and functional outcome submission
A running visit count per member per plan year against that plan's own allowance, with a provider alert raised before the threshold rather than after it. Oswestry, Neck Disability Index or the instrument the plan names, filed on the plan's schedule ahead of the re-authorization checkpoint.
PI, MVA, and workers' comp lien billing
HCFA-1500 routing to PIP/medpay, third-party liability negotiation, attorney lien documentation, and workers' comp state fee-schedule application. Settlement-time lien release packages prepared before disbursement.
Same-day E/M with manipulation (modifier 25) and the exam that is not covered
99202–99215 office E/M on the same date as CMT with modifier 25 where the E/M is significant and separately identifiable — on commercial and liability payers. On Medicare the exam itself is not a covered chiropractic service at all, so it is routed to the patient or the secondary rather than appended to the CMT claim, which is the distinction that keeps a modifier 25 pattern from becoming an audit finding.

Key Chiropractic CPT Codes
| CPT Code | Description | Medicare Amount CY2026 national, non-facility |
|---|---|---|
| 98940 | Chiropractic manipulative treatment, 1-2 spinal regions | $27 |
| 98941 | Chiropractic manipulative treatment, 3-4 spinal regions | $38 |
| 98942 | Chiropractic manipulative treatment, 5 spinal regions | $50 |
| 97140 | Manual therapy techniques, each 15 minutes | $28 |
| 97110 | Therapeutic exercises, each 15 minutes | $29 |
| 97012 | Mechanical traction therapy | $14 |
| G0283 | Electrical stimulation, unattended — the code Medicare uses instead of CPT 97014 | $13 |
| 99213 | Office visit, established patient, low-level medical decision making | $95 |
Amounts are the Medicare national unadjusted non-facility amounts for CY2026, computed from the published CMS relative value file. They are not what a commercial payer pays, and your locality adjustment moves them. A dash means Medicare publishes no amount for that code — because it is non-covered, bundled, or priced outside the fee schedule.
Why General Billing Teams Miss Chiropractic Issues
General billing staff handle dozens of specialties and rarely develop the depth needed for chiropractic coding nuances. Here is what gets missed.
Modifier and bundling errors
Specialty-specific modifier rules and CCI edits are frequently overlooked by teams that do not work exclusively in chiropractic.
Under-coding high-complexity visits
Chiropractic encounters often qualify for higher-level E/M codes, but generalist billers default to mid-level codes to avoid audit risk.
Missed payer-specific rules
Each payer has unique coverage and documentation requirements for chiropractic procedures that general teams rarely memorize.
Slow denial turnaround
Without specialty knowledge, appeal letters lack the clinical specificity needed to overturn chiropractic denials quickly.
“The AT modifier is not optional on a Medicare chiropractic claim — without it the service is read as maintenance and denied. But the costlier habit is billing Medicare for things it was never going to cover, like the exam or the x-ray, instead of routing them to the patient up front.”

Chiropractic Billing Terms
- AT Modifier
- The modifier a chiropractor places on 98940, 98941 or 98942 to indicate active or corrective treatment of an acute or chronic subluxation. CMS states that a claim without the AT modifier will be considered maintenance therapy and denied — and, in the same passage, that the presence of AT does not by itself establish that the service was reasonable and necessary. It does not apply to 98943, which Medicare does not cover.
- Subluxation Documentation
- Medicare accepts either an x-ray taken reasonably proximate to the start of the course of treatment or a physical examination. The exam route requires two of the four PART findings — pain or tenderness, asymmetry or misalignment, range of motion abnormality, and tissue or tone changes — one of which must be asymmetry or misalignment or range of motion abnormality, and the precise level of the subluxation must be named.
- Maintenance Therapy
- Chiropractic treatment that maintains or prevents deterioration of a chronic condition rather than actively treating an acute episode. Medicare does not cover maintenance care, and commercial payers may have limited or no coverage.
- CMT (Chiropractic Manipulative Treatment)
- Manual manipulation of the spine to correct a subluxation, coded by the number of spinal regions treated: 98940 for one to two, 98941 for three to four, 98942 for five. 98943 describes extraspinal manipulation and is outside the Medicare chiropractic benefit, which is limited to the spine.
- Modifier 25
- Used to indicate a significant, separately identifiable E/M service performed on the same day as a procedure. In chiropractic, allows billing an office visit in addition to manipulation when documentation supports a separate evaluation.
- Functional Outcome Measures
- Standardized instruments such as the Oswestry Disability Index or the Neck Disability Index, used to document objective change. Which instrument a plan accepts and how often it wants one are terms of that plan and product rather than an industry standard, so the schedule is read out of the contract and date-stamped.

Request ReviewDoes Medicare cover chiropractic services?
Only manual manipulation of the spine to correct a subluxation, and only where the AT modifier marks it as active or corrective treatment. Medicare does not cover the exam, the x-ray or any other diagnostic or therapeutic service furnished by a chiropractor or under a chiropractor's order, and extraspinal manipulation (98943) is non-covered as well (Medicare Benefit Policy Manual, Chapter 15, §§240 and 240.1.1, read 17 September 2026). We put the AT modifier and the subluxation documentation on every covered claim and route everything else to the patient or the secondary rather than billing it and absorbing the denial.
How do you handle denied chiropractic claims for medical necessity?
We appeal medical necessity denials with objective documentation including functional outcome measures, pain scales, and range-of-motion improvements. We also work with providers to strengthen clinical notes that demonstrate ongoing improvement and treatment necessity.
Can you bill for chiropractic exams and manipulation on the same day?
With most commercial and liability payers, yes: the office visit (99202–99215) and the manipulation (98940–98943) are separate services when the documentation supports a significant, separately identifiable evaluation, and modifier 25 goes on the E/M. Medicare is the exception — an exam performed by a chiropractor is not a covered service there, so it is billed to the patient rather than to Medicare. Note that CPT 99201 was deleted effective 1 January 2021; the established-patient range is 99211–99215 and the new-patient range starts at 99202.
