Medicare does cover chiropractic care, but only in a narrow way. Part B pays for manual spinal manipulation to correct a specific problem called a subluxation, and nothing else. That means X-rays, massage therapy, acupuncture, and any other services your chiropractor orders or performs are not covered, even if they happen during the same visit.
What Medicare Actually Covers
The only chiropractic service Medicare will pay for is manual manipulation of the spine to correct a subluxation. A subluxation is defined as an incomplete dislocation, misalignment, fixation, or abnormal spacing of the vertebrae. These fall into three categories: acute problems like strains and sprains, chronic issues like loss of joint mobility, and nerve root problems like a pinched nerve.
Your chiropractor must document the subluxation before Medicare will approve a claim. This can be done with an X-ray or a physical exam. If an X-ray is used, it needs to have been taken no more than 12 months before or 3 months after the start of your treatment course. If a physical exam is used instead, the chiropractor must document at least two of these four findings: pain or tenderness, asymmetry or misalignment, abnormal range of motion, or changes in surrounding soft tissue. One of those two findings must be either the misalignment or the range-of-motion abnormality.
The exact vertebral level of the subluxation has to appear on the claim as the primary diagnosis. The broader condition being treated, such as back pain or a nerve issue, gets listed as the secondary diagnosis.
The Maintenance Care Exclusion
This is where many people run into unexpected bills. Medicare only pays for active or corrective treatment. Once your condition has stabilized and no further objective improvement is expected, any continued visits are classified as maintenance therapy, and Medicare stops covering them.
The distinction works like this. For an acute condition (a new injury, for example), Medicare expects the manipulation to produce measurable improvement or at least stop the condition from getting worse. For a chronic condition, Medicare recognizes that full resolution may not be possible but still requires that ongoing treatment produce some functional improvement. The moment treatment shifts from corrective to supportive, keeping you at the same level rather than getting you better, it becomes maintenance care.
Maintenance therapy is broadly defined to include any services that prevent disease, promote general health, prolong quality of life, or simply maintain a chronic condition. If you see a chiropractor regularly for general wellness or to keep your back “in alignment” without an active problem being corrected, those visits will not be covered.
What You’ll Pay Out of Pocket
For covered spinal manipulation, you’re responsible for the Part B annual deductible ($257 in 2025) plus 20% coinsurance on the Medicare-approved amount for each visit. So if Medicare approves a visit at $50, you’d owe $10 after meeting your deductible.
The bigger cost risk comes from the services Medicare explicitly excludes. X-rays, exams, massage, acupuncture, and any other tests or treatments your chiropractor provides are entirely your responsibility. Many people walk into a chiropractic office expecting a full visit to be covered and are surprised to learn that only the hands-on spinal adjustment qualifies. Everything else on that visit’s bill falls to you.
Medicare Advantage Plans May Offer More
If you have a Medicare Advantage plan (Part C) instead of Original Medicare, your plan is required to cover at least the same spinal manipulation benefit. However, many Advantage plans offer supplemental chiropractic benefits beyond what Original Medicare provides. These extras vary widely by plan and may include coverage for additional services, a set number of visits per year, or lower copays. Check your specific plan’s evidence of coverage document to see what’s included, because no two Advantage plans handle this the same way.
How to Avoid Surprise Bills
Before starting treatment, ask your chiropractor two things: whether they accept Medicare assignment, and which specific services they plan to bill to Medicare versus billing you directly. A chiropractor who accepts assignment agrees to charge only the Medicare-approved amount for covered services, which limits your exposure to the 20% coinsurance. One who doesn’t accept assignment can charge up to 15% more than the approved amount.
Ask your chiropractor to be upfront about when your treatment shifts from active care to maintenance. That transition point is when Medicare coverage ends, and it can happen without a clear announcement. If your chiropractor recommends ongoing visits after your condition has plateaued, those visits are likely maintenance and you’ll be paying the full cost yourself. Getting that distinction in writing before it happens can save you from an unexpected bill weeks into your treatment.
