He Booked the Chiropractor Because Medicare Covers Adjustments. It Paid for Five Minutes in the Chair and Left the Exam, X-Ray and Heat Pack to Him

A 72-year-old wakes up with lower-back pain and books his first chiropractic visit. The front desk tells him the office accepts Medicare, and he takes that to mean the program covers the visit. Over the next hour he gets a consultation, a physical exam, an X-ray, a heat pack and a back adjustment. Only the adjustment has a path to Medicare coverage, and it took about five minutes.

This gap shows up on the bill of anyone with Original Medicare who sees a chiropractor. Medicare Advantage members should review their plan’s chiropractic benefit separately, because some plans go well beyond what Original Medicare allows.

Five Minutes Medicare Recognizes

Part B covers only spinal manipulation by a chiropractor to correct a subluxation. A subluxation means back joints that fail to move properly even though the joints still touch. The chiropractor can use their hands or a handheld device called an “activator.” After the deductible, the patient pays 20% of the Medicare-approved amount.

The deductible matters more than the 20%. The 2026 Part B deductible is $283, up from $257 in 2025. If this is his first Part B claim of the year, he pays the full approved amount for the adjustment until his covered spending reaches $283. Importantly, Original Medicare sets no annual cap on the number of covered adjustments. Coverage continues for as long as each visit qualifies as active treatment for a documented subluxation.

Coverage ends at the back. When a chiropractor bills an adjustment to a shoulder, knee, hip or any other joint as chiropractic manipulation, the patient pays for it out of pocket.

Everything Around the Adjustment Lands on Him

When the chiropractor provides or orders the following services, Medicare pays nothing for any of them:

• The initial exam, billed as a separate chiropractic service
• X-rays and other diagnostic tests
• Heat packs and electrical stimulation
• Massage or soft-tissue therapy
• Exercises, nutrition counseling and similar services

The office may bundle all of these into a single appointment. Medicare still carves out the back manipulation from everything else. Industry billing guidance tells chiropractors that exams, X-rays and therapies “can be charged at your regular” rates, and Medicare’s fee schedule sets no cap on what those charges may be.

A Medigap policy provides no relief here. Medigap pays its share only on services Medicare itself approves. Plan G picks up the 20% coinsurance on the adjustment, but pays nothing toward the exam, X-ray or heat pack.

Why the X-Ray Rarely Earns Its Price

Many patients assume the X-ray is what triggers coverage for the adjustment. It is not. A chiropractor can document the subluxation through a physical examination, and Medicare does not require new imaging before approving an adjustment. If the chiropractor takes an X-ray anyway, the patient pays for it.

The path to coverage for imaging runs through a different door. If a primary care doctor finds imaging medically necessary and orders it through an eligible Medicare provider, that X-ray may qualify under Part B. Medicare will not pay for any X-ray ordered or performed by the chiropractor, regardless of the clinical reason.

Maintenance Care Ends Coverage Mid-Treatment

Coverage for the adjustment depends on what the treatment is expected to accomplish. Medicare pays for active treatment, meaning care the chiropractor expects to improve the patient’s condition. Once the improvement plateaus and further visits would only maintain the current level of function, Medicare considers the care maintenance and stops paying. There is no fixed visit number that triggers this change; it is a clinical determination, and documentation drives the decision.

If the chiropractor expects Medicare to deny an upcoming adjustment as no longer medically necessary, the office must give the patient an Advance Beneficiary Notice (ABN) before treatment begins. The notice states the expected denial and estimated cost, and the patient can then decide whether to proceed and let Medicare rule on the claim. The chiropractor bill is one item on a longer list of premium traps and coverage gaps covered in a free Medicare guide.

Three Questions to Ask Before You Book

When an office says it accepts Medicare, that means it will submit the covered service to Medicare. Three specific answers are worth getting before the appointment begins:

1. Which service goes to Medicare? The answer should be the back adjustment, billed with the AT modifier for active treatment.
2. Which services will you bill to me directly, and at what price? Get the dollar amounts for the exam, X-ray, heat and any therapy. Ask your primary care doctor whether imaging is needed and where Medicare would cover it.
3. Are you recording my adjustment as active treatment or maintenance care? If you receive an ABN, ask which services it covers and why Medicare might deny them. An ABN does not automatically mean maintenance care.

For patients on a Medicare Advantage plan, the picture can look different. Many 2026 Advantage plans include chiropractic as a supplemental benefit and may cover exams, X-rays ordered by the chiropractor and even some maintenance visits. Most of those plans cap supplemental chiropractic at 20 to 30 visits per year and restrict coverage to in-network providers, so checking the plan’s Evidence of Coverage before booking is essential.

He booked one appointment and received several services. Only the back adjustment in the middle of it was eligible for Medicare coverage.
