HB539 replaces the current, narrow Medicare treatment of chiropractic services with a broader rule: doctors of chiropractic would be recognized as physicians for any physician’s services they are authorized to perform under state law. The bill deletes language that limited Medicare coverage to spinal manipulation for subluxation and that subjected chiropractors to uniform federal minimum standards.
The bill also adds a new payment limitation: Medicare will pay only for services furnished by a chiropractor who has been verified once through a Secretary‑designed educational webinar (or equivalent electronic product), unless the service is the traditional manual spinal manipulation to correct a subluxation. That verification requirement and the shift of scope control to state licensure are the two practical levers that will shape how Medicare expands access and how much it pays.
At a Glance
What It Does
HB539 amends Title XVIII by changing the definition in 1861(r)(5) to recognize a licensed doctor of chiropractic as a physician for any function they are legally allowed to perform in the state where they practice. It also adds a new 1833(ee) that restricts payment to chiropractors who either completed a one‑time CMS verification webinar or who provide manual spinal manipulation.
Who It Affects
Directly affected parties include Medicare fee‑for‑service beneficiaries receiving musculoskeletal care, licensed chiropractors seeking to bill Medicare for a broader set of services, and CMS operations that handle provider enrollment, claims edits, and program integrity. Indirectly, providers and health systems that refer, co‑manage, or bill for services involving chiropractors will need to update workflows and contracts.
Why It Matters
The bill shifts coverage authority from a narrowly written federal standard to a state‑license‑centered model, with only a light federal participation through a verification webinar. That combination could rapidly expand billable services and access in some states while creating jurisdictional variation, new coding and oversight questions, and potential cost pressures for the Medicare program.

What This Bill Actually Does
Currently, Medicare limits chiropractic coverage to manual manipulation of the spine to correct a subluxation and attaches certain federal minimum standards to the provider role. HB539 replaces that approach by amending the Social Security Act so a ‘‘doctor of chiropractic’’ licensed in a state is treated as a physician for any physician’s service that state law authorizes the chiropractor to perform.
The bill removes the prior statutory phrase that constrained coverage to spinal manipulation and that referenced uniform minimum standards set by the Secretary.
To control payment exposure, the bill adds a distinct limitation: Medicare will pay only for services provided by a chiropractor who has been verified once through an educational documentation webinar (or similar electronic product) designed or approved by the Secretary, unless the service is manual spinal manipulation to correct a subluxation. The webinar verification is a one‑time condition for payment; the Secretary is responsible for designing that process and any updates.Practically, the change would require CMS to alter provider enrollment and claims processing rules to accept a chiropractor as the furnishing physician for a wider array of services, and to implement the verification mechanism for payment eligibility.
The bill ties federal payment eligibility to state scope‑of‑practice: if a state authorizes a chiropractor to perform a particular function, Medicare could recognize and pay for it (subject to the verification rule).Because the statute speaks to ‘‘physicians’ services,’’ the change raises immediate questions about coding, reimbursement under the physician fee schedule, supervision and ordering relationships (for example, diagnostic imaging or referrals), and how Medicare Advantage plans will treat these services. The bill does not list covered service categories beyond the manual manipulation exception, nor does it specify payment rates or create new documentation standards beyond the webinar verification requirement, leaving significant implementation detail to CMS rulemaking and operational guidance.
The Five Things You Need to Know
The bill replaces the existing text of section 1861(r)(5) so a ‘‘doctor of chiropractic’’ licensed in the state is recognized as a physician for any function the state license authorizes.
HB539 removes the statutory reference to uniform minimum standards promulgated by the Secretary that previously limited chiropractic coverage.
A new section 1833(ee) conditions Medicare payment on either a one‑time verification—via a Secretary‑designed educational webinar or similar electronic product—or on the service being manual manipulation of the spine to correct a subluxation.
The verification requirement is explicit: the chiropractor must be ‘‘verified once’’ by a process designed by the Secretary; the bill does not define the webinar content, the verification mechanics, or renewal frequency.
Coverage under this bill is governed by state licensure: services that are outside a chiropractor’s state‑granted scope of practice would remain noncovered even after this federal change.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title
Names the measure the ‘‘Chiropractic Medicare Coverage Modernization Act of 2025.’
Findings and statement of purpose
Notes Congress's view that Medicare chiropractic coverage is outdated compared with VA, DoD, FEHB, and private insurers, and states the purpose: to expand recognition of doctors of chiropractic as physicians under Medicare for functions they are licensed to perform. This section frames the policy intent but imposes no legal obligations.
Recognize licensed chiropractors as physicians for state‑authorized functions
Rewrites the statutory definition so that a licensed doctor of chiropractic is a physician for any function or action they are legally authorized to perform in the state or jurisdiction where performed. Critically, it strikes the prior limiting language that confined Medicare coverage to manual spinal manipulation for subluxation and removed the clausal reference to Secretary‑promulgated uniform minimum standards.
Payment limitation tied to verification or manual manipulation
Adds a payment limitation requiring that Medicare pay only for chiropractic services if the furnishing chiropractor has been verified once through a Secretary‑designed educational webinar (or similar electronic product), unless the service is manual spinal manipulation to correct a subluxation. The Secretary designs the verification process; the statute is explicit that the verification is a condition of payment but leaves operational details—content, evidence of completion, and enforcement—to CMS.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Medicare beneficiaries with musculoskeletal needs — They could receive a wider range of chiropractic services covered by Medicare where state law allows, potentially improving access to non‑opioid care options and expanding onsite care in ambulatory clinics and nursing facilities.
- Licensed doctors of chiropractic — The bill creates billing opportunities beyond traditional spinal manipulation, enabling chiropractors to seek Medicare reimbursement for additional services permitted by their state scope of practice.
- Integrated care providers and health systems — Organizations that incorporate chiropractic services into care pathways (e.g., primary care clinics, rehabilitation programs, VA‑like models) may find it easier to have those services reimbursed under Medicare fee‑for‑service, supporting multidisciplinary care models.
Who Bears the Cost
- Medicare Trust Funds/CMS — Broader coverage can increase utilization and program spending; CMS will also face upfront operational costs to implement verification, update enrollment and claims systems, and manage program integrity.
- Chiropractors and small practices — They must complete the one‑time webinar verification and may need to invest in billing, documentation, and compliance upgrades to bill under physician service codes and to meet CMS documentation or audit requests.
- CMS program integrity and auditors — The removal of federal uniform minimum standards and reliance on state scope creates variable practices across jurisdictions, raising monitoring, auditing, and fraud‑detection burdens for federal enforcement bodies.
Key Issues
The Core Tension
The bill balances two competing objectives: expand beneficiary access and parity for chiropractic services by deferring to state licensure, versus the federal government’s interest in maintaining uniform quality, consistent coverage rules, and control over Medicare spending; empowering states and a light federal verification may improve access but increases variability, administrative complexity, and program integrity risk.
HB539 creates a structural shift by relying on state licensure to determine what services Medicare will recognize as physician services furnished by chiropractors, while simultaneously trimming back one central federal control (the prior reference to uniform minimum standards). That trade‑off amplifies the role of state scope‑of‑practice law and makes federal oversight downstream: CMS must decide how to certify providers, how to train them via the required webinar, and how to adjudicate claims when state and federal interpretations diverge.
The one‑time webinar verification is operationally light but vague—its content, the evidence required for payment eligibility, and whether CMS can revoke or require refresher training are unspecified, leaving significant implementation discretion to the Secretary.
The statutory change also raises practical disputes likely to surface quickly. ‘‘Physicians’ services’’ is a broad term in Medicare law; expanding that label to chiropractors invites questions about what billing codes are appropriate, whether chiropractors may bill E/M services or order and interpret diagnostic tests, and how supervision or referral relationships will operate. The bill does not address Medicare Advantage explicitly; while MA plans might already cover expanded chiropractic benefits, the interplay of FFS statutory expansion with existing contracted MA benefit design, network rules, and prior authorization remains unresolved.
Finally, relying on state licensure means coverage will vary widely across states, producing geographic inequities and complicating national program‑integrity approaches.
