Medicare Chiropractic Coverage: What You Need to Know
Medicare Chiropractic Coverage: What You Need to Know
Original Medicare Part B covers one specific chiropractic service: manual manipulation of the spine to correct a vertebral subluxation. That’s it. If your chiropractor plans to do anything else during your visit, whether that’s X-rays, massage, physical therapy modalities, or nutritional counseling, Medicare will not pay for those services when billed by a chiropractor. The first thing you should do before scheduling an appointment is call the office and ask two questions: “Do you accept Medicare Part B?” and “Will you bill Medicare directly for my spinal manipulation?”
Key facts to keep in mind before your first visit:
- Original Medicare Part B covers only manual spinal manipulation to correct a subluxation.
- After meeting your Part B deductible, you typically pay 20% of the Medicare-approved amount.
- Medicare does not cover X-rays, massage, acupuncture, or office visits when billed by a chiropractor.
- The chiropractor must be Medicare-participating and must bill Part B for the manipulation.
- Coverage applies only to active, corrective treatment, not ongoing maintenance care.
Key Takeaways
Medicare covers spinal manipulation for subluxation correction under Part B, but documentation, coding, and provider participation must all be confirmed before your first visit.
| Point | Details |
|---|---|
| Coverage is narrow | Original Medicare Part B covers only manual spinal manipulation to correct a vertebral subluxation. |
| Cost-sharing under Part B | After meeting your Part B deductible, you typically pay 20% of the Medicare-approved amount. |
| AT modifier is required | Claims for active chiropractic treatment must include the AT modifier; its absence typically results in denial. |
| Maintenance care is not covered | Once your condition stabilizes, further manipulation is considered maintenance therapy and Medicare will not pay. |
| Mountaintop Insurance | Offers free consultations to help Central Oregon beneficiaries review chiropractic benefits and compare plan options. |

What Medicare actually means by “chiropractic services”
Medicare’s definition is narrower than most people expect. “Manual manipulation of the spine” means hands-on treatment applied directly to the vertebrae to correct a subluxation. Chiropractors may also use hand-held manual devices during the manipulation and still bill the same manipulation codes, but Medicare does not recognize a separate charge for the device itself.
A subluxation, in Medicare’s terms, is a partial dislocation of a vertebral joint that is clinically significant enough to cause neurological, vascular, or connective tissue compromise. The chiropractor must document it through either a physical examination or X-ray evidence. The documentation must specify the level of the spine affected, not just note that a subluxation exists.
The CPT codes that map to covered chiropractic manipulative treatment are:
- CPT 98940: Manipulation of 1–2 spinal regions
- CPT 98941: Manipulation of 3–4 spinal regions
- CPT 98942: Manipulation of 5 spinal regions
- CPT 98943: Extraspinal manipulation (NOT covered by Medicare)
Pro Tip: When you call a chiropractic office, ask specifically: “Will you bill CPT 98940, 98941, or 98942 to Medicare Part B, and will you use the AT modifier?” If the staff cannot answer that question, ask to speak with the billing department before booking.
How Medicare decides whether your chiropractic care qualifies
Coverage hinges on two concepts: medical necessity and active treatment. Medicare defines medically necessary care as treatment that a reasonable physician would consider appropriate for diagnosing or treating a condition, with a realistic expectation of improvement or restored function. For spinal manipulation, that means the chiropractor must document that your condition is expected to improve, not simply that manipulation makes you feel better temporarily.
The active versus maintenance distinction is where many claims run into trouble. Once your clinical status has stabilized and further manipulation is unlikely to produce additional functional improvement, Medicare considers ongoing treatment to be maintenance therapy, which is not covered. The chiropractor must document measurable change at each visit, not just note that treatment was provided.
What documentation supports medical necessity:
- Patient history, including onset, duration, and character of symptoms
- Physical examination findings at each visit
- Objective measurement of functional change since the last visit
- The specific subluxation level and how it was identified
- The treatment provided and the patient’s response
Local Coverage Determinations (LCDs) issued by Medicare Administrative Contractors (MACs) add another layer. LCDs specify which ICD-10 diagnosis codes support medical necessity in a given region and may group diagnoses by expected treatment length, short, moderate, or long. Your chiropractor’s LCD may differ from one in another state, so it’s worth knowing which MAC covers your area.
CMS data on chiropractic services has shown a 33.6% improper payment rate with $178.3 million in projected improper payments, the vast majority driven by insufficient documentation. That number reflects why getting the paperwork right matters as much as getting the diagnosis right.
What chiropractic care costs under Original Medicare
There is no annual visit cap under Original Medicare for chiropractic manipulation, but coverage stops when care shifts from active to maintenance treatment, regardless of how many visits you’ve had.
A few cost realities to keep in mind:
- Medicare sets the approved amount through the Physician Fee Schedule. The chiropractor cannot charge you more than that amount if they are Medicare-participating.
- If the chiropractor performs non-covered services during the same visit, those are billed to you privately. Medicare will not pay for them, and the chiropractor should give you an Advance Beneficiary Notice of Noncoverage (ABN) before providing them.
- Medicare will not pay extra for a hand-held manipulation device, even if the chiropractor charges separately for it.
Pro Tip: Before your first treatment, ask the office for a written breakdown showing which services will be billed to Medicare and which will be billed to you directly. This prevents surprise charges and helps you compare the true out-of-pocket cost across providers.
Medicare Advantage (Part C) plans may offer additional chiropractic benefits beyond what Original Medicare allows, but those vary by plan.
Services Medicare will not cover when billed by a chiropractor
Medicare explicitly excludes a range of services when they are ordered or performed by a chiropractor. Knowing this list in advance prevents the most common billing surprises:
- X-rays taken or ordered by the chiropractor (see the X-ray rule below)
- Office visits and history-and-physical exams billed by the chiropractor
- Physical therapy modalities such as ultrasound, electrical stimulation, or traction
- Massage therapy
- Acupuncture
- Laboratory tests ordered by the chiropractor
- Injections or drugs
- Nutritional supplements
- Extraspinal manipulation (CPT 98943, which covers areas outside the spine)
The X-ray rule deserves its own explanation. Chiropractors are not required to obtain X-rays before treatment, and when X-rays are used to document subluxation, they should be reasonably close in time to the start of treatment. However, Medicare will only reimburse diagnostic X-rays when they are ordered by an MD or DO, not by the chiropractor. If your chiropractor takes X-rays in-office and bills Medicare for them, the claim will be denied.
One practical workaround: some chiropractic offices intentionally submit non-covered services to Medicare to receive a formal denial. That denial letter can then be submitted to a secondary insurer, such as a Medigap plan or employer retiree coverage, which may pay for services Medicare won’t. Ask your office whether they follow this practice if you carry secondary coverage.
Pro Tip: Before any service is performed, ask the billing staff: “Is this billable to Medicare, and if not, will you submit it to Medicare for a denial so I can use it with my secondary insurance?”
Billing, coding, and documentation: what Medicare expects
Getting paid requires the right codes, the right modifier, and the right documentation. CMS billing guidance is specific about all three.
The AT modifier is the critical piece. It must appear on every claim line for active, corrective chiropractic treatment. Without it, Medicare treats the claim as maintenance therapy and denies it for lack of medical necessity. The AT modifier signals that the manipulation is intended to correct a subluxation, not simply maintain a stable condition.
| CPT Code | Spinal Regions Treated | Key Documentation Required |
|---|---|---|
| 98940 | 1–2 regions | Subluxation level, physical exam findings, functional status |
| 98941 | 3–4 regions | Same as above, plus response to prior treatment |
| 98942 | 5 regions | Full documentation of all five regions, clinical justification |
For ICD-10 coding, the primary diagnosis must identify the specific level of subluxation, for example, M99.01 (segmental dysfunction, cervical region). Secondary diagnoses can support the necessity of treatment but cannot substitute for a subluxation-specific primary code.
MLN Matters SE1601 outlines what an initial visit record must include: chief complaint, history of present illness, family and social history where relevant, review of systems, physical examination, diagnosis, treatment plan, and date of initiation of care. Subsequent visit records must document the patient’s subjective response, objective findings, assessment of change, and the treatment provided that day.
Pro Tip: If your Explanation of Benefits (EOB) shows a denial or unexpected patient liability, request a copy of the submitted claim and the provider’s clinical notes. Those two documents are the foundation of any successful appeal.
How to get Medicare to pay for your chiropractic care
Follow these steps in order to maximize your chance of Medicare covering your spinal manipulation:
- Confirm Medicare participation. Call the chiropractic office and ask: “Are you a Medicare-participating provider, and will you bill Medicare Part B for my spinal manipulation?” A provider who accepts Medicare assignment cannot charge you more than the Medicare-approved amount.
- Verify the documentation plan. Ask how the chiropractor will document your subluxation, whether through physical exam findings or X-ray. If X-ray is needed for reimbursement purposes, confirm it will be ordered by an MD or DO.
- Understand the treatment timeline. Ask how many visits the chiropractor expects for active treatment and what improvement markers will be tracked. Your MAC’s LCD may specify expected visit counts by diagnosis group.
- Review your Medicare Summary Notice (MSN). After claims are processed, your MSN shows what was billed, what Medicare approved, and what you owe. Check that the AT modifier appears on covered manipulation lines and that no non-covered services were billed to Medicare without your knowledge.
- Appeal a denial if warranted. You have the right to appeal any Medicare coverage decision. The denial notice will include appeal instructions and deadlines. Gather the submitted claim, the provider’s clinical notes, and any supporting documentation of medical necessity before filing.
Documents to request from your provider if you plan an appeal:
- The submitted claim (CMS-1500 form or electronic equivalent)
- Clinical notes from the disputed visit(s)
- The chiropractor’s treatment plan and documented functional goals
- Any X-ray reports used to establish subluxation
Pro Tip: Medicare appeals at the first level (redetermination) must be filed within 120 days of receiving your MSN. Missing that window forfeits your right to that appeal level.
How Medicare Advantage and Medigap handle chiropractic differently
Original Medicare draws a hard line at spinal manipulation for subluxation correction. Medicare Advantage plans can go further. Many Part C plans include additional chiropractic benefits such as coverage for maintenance visits, a set number of annual visits, or reduced cost-sharing. The catch is that these benefits vary widely from plan to plan and year to year.
A few things to know before assuming your plan covers more:
- Check your plan’s Evidence of Coverage (EOC) document under the chiropractic or musculoskeletal section. The EOC is the binding description of your benefits.
- Some Medicare Advantage plans require prior authorization for chiropractic visits. Skipping this step can result in full out-of-pocket liability even for otherwise covered services.
- Network restrictions apply. A chiropractor who accepts Original Medicare may not be in your Advantage plan’s network.
Medigap works differently. It does not add new covered services. Reviewing your Medigap options before you need ongoing chiropractic care can meaningfully reduce your annual out-of-pocket exposure.
Pro Tip: When comparing Medicare Advantage plans during open enrollment, look specifically at the chiropractic benefit section in each plan’s Summary of Benefits. If you expect regular musculoskeletal care, this line item can be worth hundreds of dollars annually.
How a local Medicare agent can help you use your chiropractic benefits
A Medicare agent cannot file claims for you or practice medicine, but they can do several things that save you real money and frustration. They can pull up your plan’s EOC and walk through the chiropractic benefit with you line by line. They can compare Medicare Advantage plans side by side on chiropractic coverage, visit limits, and cost-sharing. And they can help you understand whether a Medigap policy would reduce your exposure on Part B-covered manipulation.
What to bring to a consultation with a Medicare agent:
- Your current Medicare card (showing your Medicare Beneficiary Identifier)
- A recent Medicare Summary Notice or Explanation of Benefits
- The name of your current or prospective chiropractor
- Any provider notes or treatment plans you have received
Mountaintop Insurance offers free consultations for Medicare-eligible residents of Central Oregon. The focus is education: understanding what your current plan covers, identifying gaps, and walking through your options without pressure to enroll in anything. If you’re unsure whether your chiropractic care qualifies under your current plan, or whether switching to a Medicare Advantage plan with expanded chiropractic benefits makes sense for your situation, that conversation is a good place to start.
Pro Tip: Bring your most recent MSN to the consultation. It shows exactly how your current plan processed recent claims and makes it easy to spot billing errors or coverage gaps.
What beneficiaries most often get wrong about chiropractic coverage
Most coverage problems are preventable. The mistakes tend to cluster around three assumptions that turn out to be wrong.
The first is assuming the chiropractor accepts Medicare. Not every licensed chiropractor participates in Medicare, and some who do accept Medicare still won’t bill it directly. Confirm both facts before your first appointment, not after you’ve received care.
The second is taking a verbal assurance about coverage at face value. “We bill Medicare” is not the same as “Medicare will cover this specific service.” Ask for a written estimate that separates Medicare-billable services from privately billed ones.
The third is assuming that X-rays taken in the chiropractor’s office will be covered. They won’t be, unless ordered by an MD or DO. If your chiropractor recommends imaging, ask whether the order will come from a physician and whether the X-ray will be taken at a facility that bills Medicare separately.
