Q: What does chiropractic billing include?

Full-cycle RCM for chiropractic practices: spinal manipulation coding by region count, the Medicare AT modifier only for active treatment, maintenance lines with an ABN when the patient was told Medicare will not pay, commercial exams that sit outside the Medicare cap, claim scrubbing, submission, payment posting, denial management, and A/R follow-up.

Q: What does Medicare pay a chiropractor?

Medicare pays manual manipulation of the spine to correct a subluxation: 98940 for one to two regions, 98941 for three to four, and 98942 for five. An exam, x-ray, extraspinal manipulation, and therapy modalities are outside that benefit. Modifier AT is required for active or corrective treatment. Maintenance care is not paid.

Q: When is the AT modifier used?

AT goes on 98940, 98941, or 98942 only when the visit is active or corrective treatment of an acute or chronic subluxation and further improvement is still expected. Do not use AT for maintenance. Do not put AT and GA on the same line. AT does not by itself prove the service was necessary.

Q: Do we have to change our EHR?

No. Billers work in the practice management system or EHR you already use. Compatibility is confirmed before you commit.

Chiropractic billing is spinal manipulation codes, including the Medicare limit — and an exam that is outside that cap. Vector Medical Billing, in Jamaica, New York, matches the regions adjusted, keeps AT off maintenance visits, and splits the commercial exam from the Medicare-only manipulation line inside the EHR you already use.

What chiropractic billing services include

Full-cycle RCM for chiropractic offices — the spinal code Medicare will pay, and everything else billed only where a plan actually covers it.

The operating cycle matches medical billing services: eligibility, charge capture from the adjustment note, ICD-10 / CPT coding, scrub, clearinghouse submission, payment posting, denial management, and A/R follow-up. The scrub watches region count versus 98940, 98941, or 98942, the AT modifier, maintenance versus active treatment, and whether an exam or modality was sent to Medicare.

In scope: spinal chiropractic manipulative treatment, the subluxation and the related condition on the claim, commercial exams and therapies when that plan covers them, and maintenance visits billed so the patient — not a silent write-off — knows Medicare will not pay. Timed physical therapy and occupational therapy under a therapy plan of care stay on those pages. This is not a therapy claim with a chiropractic diagnosis.

Chiropractic is priced as a percentage of net collections because the Medicare spinal-only benefit and the active-versus-maintenance decision take extra scrub time. The written rate follows Medicare versus commercial mix — see pricing. Credentialing, a retrospective coding audit, MIPS, and out-of-network / IDR are separate engagements.

Where chiropractic claims fail

Common chiropractic billing issues include the AT modifier on a maintenance visit, a spinal region count that does not match the note, and exams or imaging billed to Medicare as if they were part of the chiropractic benefit.

AT on a maintenance visit

Every adjustment stamped AT after the patient has plateaued. Or a true active visit sent without AT, so Medicare treats it as maintenance and denies it.

AT means active or corrective treatment is still expected to change function.

Wrong region count

98942 billed when the note lists two regions. 98940 billed after cervical, thoracic, and lumbar were all adjusted. Extraspinal 98943 sent to Medicare.

The code is the number of spinal regions treated, not a visit level.

Exam inside the Medicare cap

An office visit, x-ray, or modality billed to Medicare as if the chiropractic benefit included it. Or AT and GA on the same manipulation line.

The exam sits outside the cap. Maintenance uses the ABN path, not AT.

Spinal manipulation coded by the number of regions

Spinal CMT

Spinal manipulation codes, and the Medicare limit

Medicare’s chiropractic benefit pays three spinal adjustment codes, and it does not pay the rest of a typical chiropractic visit.

98940 is chiropractic manipulative treatment of one to two spinal regions. 98941 is three to four. 98942 is five. Count the regions in the note — cervical, thoracic, lumbar, sacral, pelvic — and pick the code that matches. Do not step up to 98942 because the visit was long. Medicare’s chiropractic benefit is manual manipulation of the spine to correct a subluxation. Extraspinal manipulation (98943), examinations, x-rays ordered or taken by the chiropractor, and therapy modalities are outside that benefit. Sending them to Medicare produces a non-covered denial, not a coding tweak that makes them payable.

The primary diagnosis is the level of subluxation. The secondary diagnosis is the related neuromusculoskeletal condition. The initial treatment date, or the date of an exacerbation, belongs on the claim the way that Medicare contractor asks for it. A note that never names the regions treated cannot support any of the three codes.

Active treatment versus maintenance

AT is not a habit modifier. Maintenance is a different claim.

When AT belongs

Use AT on 98940, 98941, or 98942 only for active or corrective treatment. Acute means a new injury, shown by exam or imaging, where improvement or an arrest of progression is expected. Chronic means a longer-standing subluxation where further functional improvement is still expected. Once the status is stable and more care would only maintain it, the visit is maintenance. AT does not prove necessity. A review can still deny the line if the record does not show active treatment. The exam that demonstrates subluxation uses pain, asymmetry, range-of-motion change, and tissue-tone findings — at least two of those, and one of them asymmetry or range of motion — or an x-ray. That exam still is not a Medicare-paid line.

Maintenance, GA, and the ABN

Leave AT off maintenance. Medicare denies 98940–98942 without AT as maintenance. If the patient wants to continue and was told Medicare is not expected to pay, a signed Advance Beneficiary Notice supports modifier GA. Do not put AT and GA on the same line — contractors reject that pair. GZ is the flag when a denial is expected and no ABN was signed; the patient is not billed for that line. GY is for a service that has no Medicare benefit at all, such as an exam billed only so the denial is on file. Do not use GA to collect for a visit you also marked as active treatment.

The exam that sits outside the cap

Commercial plans are not the Medicare spinal benefit.

Medicare

An exam, x-ray, extraspinal adjustment, and modalities such as mechanical traction or manual therapy are outside the chiropractic benefit. They are not added with modifier 25 to make Medicare pay them. If the patient is informed and an ABN applies, bill the non-covered line with the modifier that matches that notice — not as a covered CMT extra.

Commercial exams

Many commercial plans pay an evaluation and the manipulation on the same day when the exam is significant and separately identifiable and the plan does not bundle it into CMT. Modifier 25 then sits on the exam, not on 98940. A brief check that only sets up the adjustment is not a second code. Read that plan’s edit before 25 becomes a habit.

Therapy in the same office

If the practice also bills timed therapy under a physical or occupational therapy plan, those units follow the physical therapy or occupational therapy rules and modifiers. They are not extra spinal regions, and they are not Medicare chiropractic lines.

This page does not invent a chiropractic denial percentage. The free audit reads your region counts and AT use on the sample you send.

What a free audit line looks like

Illustrative composite only — not a client result and not a promised recovery.

Documented service

Medicare patient, week 14. Note says status stable, no further functional change expected. Cervical and lumbar adjusted. A new exam and mechanical traction were also performed. No ABN.

Billed codes

98941-AT, 99213-25, and 97012 to Medicare

Issue found

Region count is two, not three or four. AT used after the note describes maintenance. Exam and modality are outside the Medicare benefit. No ABN, so GA is not available.

Recommended correction

If the visit is truly maintenance, bill 98940 without AT and do not bill the patient unless an ABN was signed first. Drop 99213 and 97012 from the Medicare claim.

Related check

Subluxation level is primary; the pain or sprain code is secondary

Why it matters

AT on maintenance and an exam inside the cap deny or recoup — caught in scrub or flagged in the free audit

How Vector runs chiropractic billing

Regions and active-versus-maintenance first — then the same revenue cycle.

Assign chiropractic RCM

Coder and biller who already split Medicare CMT from commercial exams.

Reconcile and code

Charge entry and coding from the adjustment note — queries when regions or the treatment phase are unclear.

Scrub and submit

Claims submission after region, AT, and Medicare-cap checks.

Post and report

835 posting, denial work, A/R aging, monthly RCM report by Medicare CMT versus commercial exam.

Not inside the chiropractic percentage

Related work stays separate so the quote matches the job.

Therapy plans of care

Timed PT or OT under a certified therapy plan is a different engagement when that is most of the schedule. Spinal CMT stays on this page.

Credentialing / audit

Credentialing and a retrospective coding audit of AT use are separate engagements when scoped.

Underpay / OON

Underpayment recovery and OON / IDR are handled separately when the dispute path is not ordinary denial work.

How chiropractic billing is priced

Percentage of dollars that land — not a flat fee per adjustment that ignores maintenance denials.

Written rate

Chiropractic is priced as a percentage of net collections because active-versus-maintenance decisions and the Medicare spinal-only benefit take more scrub time. No setup fee on the monthly cycle. Month to month. The written rate follows Medicare versus commercial mix and how much of the cycle you hand over.

See pricing or request a written rate after the free audit.

What we need to start

EHR access, Medicare versus commercial mix, how maintenance visits are handled today, open A/R if you are leaving another biller, and a sample of AT or non-covered denials. Switching usually overlaps so claim submission does not stop. See EHR integration if access setup needs a separate quote.

Audit the adjustments that still carry AT after the patient has plateaued

Send monthly visit volume, Medicare share, EHR name, and a sample of AT or exam denials. We reply with what the open A/R shows, whether the monthly fee fits, and a written rate — without inventing a clean-claim percentage.
