Why a cash chiropractic practice still files Medicare claims, and for exactly one thing

Can a chiropractic practice be cash only with Medicare patients?

Almost. Everything a chiropractor does other than manual manipulation of the spine sits outside Medicare, and a practice can price all of it as cash. The manipulation is the exception, and it is a narrow one. Medicare treats a chiropractor as a physician for that single modality only, and only where a manipulation the chiropractor is legally authorized to perform corrects a subluxation 1Ref 1U.S. Congress (codified by the Office of the Law Revision Counsel) (2024).42 U.S. Code § 1395x — Definitions (subsection (r), paragraph (5): chiropractor).The statutory limit that treats a chiropractor as a Medicare physician only with respect to manual manipulation of the spine to correct a subluxation the chiropractor is legally authorized to perform..

That narrowness cuts both ways. The examination, the imaging, the soft-tissue work, the supplies and the plan of care never touch a claim form, because Medicare was never going to pay for any of them. But the adjustment that meets the coverage condition drags a claim behind it, whatever the patient handed over at the front desk.

So the working question is which single service crosses back into Medicare, and what the crossing costs in paperwork.

What Medicare pays a chiropractor for, and what it never pays for

One service, on one condition. Medicare Part B pays for a chiropractor's manual manipulation of the spine to correct a subluxation, and only where that subluxation has resulted in a neuromusculoskeletal condition for which manipulation is the appropriate treatment 2Ref 2Centers for Medicare & Medicaid Services (CMS), Department of Health and Human Services (2024).42 CFR § 410.21 — Chiropractors' services: Conditions and limitations.The Part B coverage condition for manual manipulation (a subluxation that has resulted in a neuromusculoskeletal condition for which manipulation is appropriate treatment), the exclusion of x-rays and any other diagnostic or therapeutic service a chiropractor furnishes or orders, and the post-June-30-1974 licensure threshold of a four-year program of at least 4,000 hours after two years of pre-chiropractic college study.. The same regulation states the other half plainly: Part B does not pay for x-rays, or for any other diagnostic or therapeutic service a chiropractor furnishes or orders 2Ref 2Centers for Medicare & Medicaid Services (CMS), Department of Health and Human Services (2024).42 CFR § 410.21 — Chiropractors' services: Conditions and limitations.The Part B coverage condition for manual manipulation (a subluxation that has resulted in a neuromusculoskeletal condition for which manipulation is appropriate treatment), the exclusion of x-rays and any other diagnostic or therapeutic service a chiropractor furnishes or orders, and the post-June-30-1974 licensure threshold of a four-year program of at least 4,000 hours after two years of pre-chiropractic college study..

Who counts as a chiropractor for this purpose has a floor of its own. For anyone licensed after June 30, 1974, the regulation requires a four-year chiropractic program of at least 4,000 hours, taken after two years of pre-chiropractic college study, and a separate older standard governs licensure before July 1, 1974 2Ref 2Centers for Medicare & Medicaid Services (CMS), Department of Health and Human Services (2024).42 CFR § 410.21 — Chiropractors' services: Conditions and limitations.The Part B coverage condition for manual manipulation (a subluxation that has resulted in a neuromusculoskeletal condition for which manipulation is appropriate treatment), the exclusion of x-rays and any other diagnostic or therapeutic service a chiropractor furnishes or orders, and the post-June-30-1974 licensure threshold of a four-year program of at least 4,000 hours after two years of pre-chiropractic college study.. Below that floor the coverage question never arises.

The exclusion is where the cash practice lives. Medicare pays nothing toward those services, so there is no allowed amount to discount from and nothing on a fee schedule to point at.

Why opting out is closed to a chiropractor

Because the regulation that creates the opt-out route names who may use it, and chiropractors are in neither list. Medicare's private-contracting subpart is where the terms opt out and private contract are defined at all, along with the narrow emergency and urgent care exceptions that let an opted-out clinician still be paid through Medicare channels 3Ref 3Centers for Medicare & Medicaid Services (Code of Federal Regulations) (2026).42 CFR § 405.400 — Definitions.That Medicare's opt-out subpart is where the terms opt out and private contract are defined, together with the narrow emergency and urgent care exceptions under which an opted-out clinician can still be paid through Medicare channels.. The route is open to two named classes.

The first is physician, defined for this subpart as a doctor of medicine, a doctor of osteopathy, a doctor of dental surgery or dental medicine, a doctor of podiatric medicine, or a doctor of optometry 4Ref 4Centers for Medicare & Medicaid Services (CMS), Department of Health and Human Services (2024).42 CFR § 405.400 — Basis, scope, and definitions (Medicare private contracts / opt-out subpart).The two closed definitional lists that decide opt-out eligibility for this subpart: five named physician doctorates, and a separate named list of non-physician practitioners, neither of which includes chiropractors.. The second is practitioner: physician assistants, nurse practitioners, clinical nurse specialists, certified registered nurse anesthetists, certified nurse midwives, clinical psychologists, clinical social workers, marriage and family therapists, mental health counselors, and registered dietitians or nutrition professionals 4Ref 4Centers for Medicare & Medicaid Services (CMS), Department of Health and Human Services (2024).42 CFR § 405.400 — Basis, scope, and definitions (Medicare private contracts / opt-out subpart).The two closed definitional lists that decide opt-out eligibility for this subpart: five named physician doctorates, and a separate named list of non-physician practitioners, neither of which includes chiropractors..

Neither list mentions chiropractors, and the omission is the whole argument. Nothing in the subpart says a chiropractor may not opt out. It enumerates who may, twice, in closed lists, and a profession absent from both has no doorway. Read the current text before relying on this, because an enumerated list is the kind of provision that gets amended.

A cash agreement can still say what the patient pays. But it cannot take the manipulation out of Medicare, because that is the work a private contract does and the private-contract route is not available here. A practice that wants a signed cash agreement covering the non-covered menu is on different ground, and a health care attorney who works with chiropractic practices is the right reader for that draft before it goes in front of patients.

The claim that gets filed anyway

Every covered manipulation gets a claim, whatever the patient paid. The submission duty in Social Security Act section 1848(g)(4) reaches every covered service furnished to a Medicare beneficiary and holds regardless of any private fee arrangement. It carries a civil monetary penalty of up to $2,000 per violation, and it bars a practice from charging the patient to prepare or file the claim 5Ref 5Noridian Healthcare Solutions (CMS Medicare Administrative Contractor, Jurisdiction E Part B) (2025).Mandatory Claim Submission - JE Part B.The Social Security Act section 1848(g)(4) duty to submit a claim for every covered service furnished to a Medicare beneficiary regardless of any private fee arrangement, the civil monetary penalty of up to $2,000 per violation, and the bar on charging a patient to prepare or file the claim..

Two obligations therefore sit on the same visit and answer to different rules. What the patient pays is a matter between the patient and the practice. Whether a claim goes to the Medicare Administrative Contractor is a matter between the practice and Medicare, and the second one does not move when the first one changes.

The penalty is written per violation and the duty per covered service furnished, so exposure grows with visit volume rather than with patient count 5Ref 5Noridian Healthcare Solutions (CMS Medicare Administrative Contractor, Jurisdiction E Part B) (2025).Mandatory Claim Submission - JE Part B.The Social Security Act section 1848(g)(4) duty to submit a claim for every covered service furnished to a Medicare beneficiary regardless of any private fee arrangement, the civil monetary penalty of up to $2,000 per violation, and the bar on charging a patient to prepare or file the claim.. A patient seen weekly generates a weekly obligation.

Filing a few claims a month without a billing department

Electronically, under one NPI, through the Medicare Administrative Contractor for the jurisdiction. Medicare's baseline since the Administrative Simplification Compliance Act is that an initial claim is payable only when it is submitted electronically, with a small-provider exception written as numeric thresholds on full-time-equivalent employee count and average claims per month 6Ref 6Centers for Medicare & Medicaid Services (2003).§ 424.32 Basic requirements for all claims.The Administrative Simplification Compliance Act baseline that an initial Medicare claim is payable only if submitted electronically, and the existence of numeric small-provider exceptions keyed to full-time-equivalent employee counts and average claims per month.. Those thresholds are where a low-volume practice finds out which side of the line it sits on, and 42 CFR 424.32 carries the current figures.

A second identity is not on offer either. An individual clinician is eligible for one Type 1 NPI, there is no second NPI for a second role, and a Medicare claim submitted without an NPI is unprocessable 7Ref 7Noridian Healthcare Solutions, LLC (Medicare Administrative Contractor for CMS) (2026).National Provider Identifier (NPI) - JE Part B.That an individual clinician is eligible for only one Type 1 NPI, with no second NPI for a second role, and that a submitted Medicare claim without an NPI is unprocessable.. The cash side and the Medicare side of one practice run under the same number.

Filing electronically also raises a question about which of HIPAA's rules reach the practice, and the covered-entity test is what answers it. A denied manipulation claim has an appeal route of its own, where level one is a Medicare redetermination with the MAC, and that deadline belongs on the calendar the day the denial arrives.

Pricing the cash side with no Medicare rate underneath it

There is no Medicare allowable underneath the cash side, because Medicare pays nothing toward the services being priced. The examination, the imaging, the soft-tissue work and the plan of care sit outside Part B entirely 2Ref 2Centers for Medicare & Medicaid Services (CMS), Department of Health and Human Services (2024).42 CFR § 410.21 — Chiropractors' services: Conditions and limitations.The Part B coverage condition for manual manipulation (a subluxation that has resulted in a neuromusculoskeletal condition for which manipulation is appropriate treatment), the exclusion of x-rays and any other diagnostic or therapeutic service a chiropractor furnishes or orders, and the post-June-30-1974 licensure threshold of a four-year program of at least 4,000 hours after two years of pre-chiropractic college study., so no fee-schedule amount exists to discount from, mark up, or hold up in a conversation about price. The number comes out of the practice's own arithmetic and nowhere else.

That arithmetic is short. Take the price of the visit, subtract the room, the table, the software, the card processing, the malpractice premium and the hour it took, and what remains is what the visit contributed. Run the subtraction list across a month of real appointments and it answers a question no benchmark can: whether this schedule, in this town, at this price, carries the practice.

No published benchmark for chiropractic cash pricing turned up in the federal record behind this article, and a figure invented to fill that gap would be worse than the gap.

One line in the pricing conversation is fixed from outside. The claim on the covered manipulation cannot become a billable service, because charging the patient to prepare or file it is barred 5Ref 5Noridian Healthcare Solutions (CMS Medicare Administrative Contractor, Jurisdiction E Part B) (2025).Mandatory Claim Submission - JE Part B.The Social Security Act section 1848(g)(4) duty to submit a claim for every covered service furnished to a Medicare beneficiary regardless of any private fee arrangement, the civil monetary penalty of up to $2,000 per violation, and the bar on charging a patient to prepare or file the claim., so those minutes belong in overhead with the rest of the visit's cost.
