Chiropractic insurance billing in Massachusetts.

Medicare’s chiropractic rules are federal — the same in every state. Medicare Part B covers ONLY manual manipulation of the spine to correct a subluxation (CPT 98940–98942), and ONLY when the care is active or corrective — which you signal with the AT modifier. Maintenance care, exams, X-rays, and any therapies performed by a chiropractor are not covered, so a properly executed ABN is essential before non-covered services. The full federal rules are in our chiropractic Medicare billing guide.

Part B claims in Massachusetts are processed by National Government Services (JK) — its Local Coverage Determination and documentation expectations (and its audits of the AT modifier and medical necessity) are the ones your Massachusetts claims are measured against.

A Massachusetts chiropractic or multi-specialty practice spends most of its commercial billing day with: Blue Cross Blue Shield of Massachusetts; Harvard Pilgrim Health Care (Point32Health); Tufts Health Plan (Point32Health); WellSense Health Plan;

Mass General Brigham Health Plan; UnitedHealthcare. Each has its own claim portal, fee schedule, and chiropractic medical-policy quirks.

Which delegated chiropractic/musculoskeletal network manager applies in Massachusetts determines where enrollment, authorizations/treatment plans, and CLAIMS go — sending them to the wrong entity is a leading denial cause.

• American Specialty Health (ASH) — a national specialty-network manager that is active in Massachusetts and administers chiropractic (often plus acupuncture) for plans that delegate to it; notably, Cigna has moved chiropractic and acupuncture network management, credentialing, and claims processing to ASH (ashlink.com / ashcompanies.com), so for Cigna members in MA those functions route to ASH, not Cigna. ASH historically also supports Aetna, Anthem, and Health Net lines in various markets.
• Optum / Optum Physical Health (UnitedHealth Group) manages outpatient PT/OT/ST and chiropractic for UnitedHealthcare; UHC requires prior authorization for chiropractic/therapy for Medicare Advantage members with reviews delegated to Optum (CMS Chapter 15 criteria, applicable LCDs, InterQual), and the requirement takes effect in Massachusetts Jan. 1, 2026 (routine maintenance care excluded).
• Blue Cross Blue Shield of Massachusetts runs its OWN chiropractic authorization program rather than ASH/Optum: authorization/continued review for visits 13 and beyond is administered through WholeHealth Living, Inc. (a Tivity Health company), while broader BCBSMA utilization management uses Carelon Medical Benefits Management (formerly AIM Specialty Health).
• Harvard Pilgrim/Tufts (Point32Health) generally administer chiropractic in-house under their own payment policy and prior-authorization rules. CRITICAL for MA chiropractic billing: confirm on the member’s card/portal whether chiropractic is carved out (ASH for Cigna; Optum for UHC) or handled by the plan’s own program (BCBSMA via WholeHealth Living; Point32Health in-house) BEFORE submitting auths or claims, since delegation varies by plan/product and changes over time.

What actually trips up chiropractic billing in Massachusetts:

• State coverage mandate / parity — M.G.L. c. 175 s. 108D (with parallel provisions for nonprofit hospital/medical service corporations and HMOs in c. 176A, 176B and 176G) requires that when a Massachusetts-regulated policy reimburses a service that is within a licensed chiropractor’s lawful scope of practice, the insured is entitled to reimbursement whether the service is performed by a physician OR a chiropractor — a non-discrimination/parity mandate, NOT an unlimited-visit mandate. It does NOT reach self-funded ERISA plans (common among large MA employers), so always check whether the plan is fully insured (mandate applies) or self-funded (it may not). Some commercial products cover chiropractic only when the member has a ‘chiropractic rider.’
• Visit caps, medical necessity and continued review — BCBSMA commonly applies an initial benefit (e.g., 12 visits) with required authorization/continued clinical review for visit 13 and beyond through WholeHealth Living; Harvard Pilgrim plans commonly cap chiropractic (e.g., ~20 visits/plan year); plans require a documented treatment plan, periodic re-evaluation, and a transition from active/corrective care to non-covered maintenance care.
• Reimbursement-policy quirks — BCBSMA implemented a Multiple Therapy Procedure Reduction (MTPR) policy (effective April 1, 2025) cutting reimbursement for second and subsequent same-day therapy services, which directly hits chiropractic offices billing manipulation plus therapy modalities; watch same-day modality stacking.
• Modifiers/pre-auth — expect the AT (active treatment) modifier on Medicare/Medicare-Advantage spinal manipulation (98940-98942), correct GA/GY/GZ and -59/X{EPSU} usage when distinct services are billed, and NEW prior authorization for chiropractic/therapy under UHC/Optum Medicare Advantage effective in MA Jan. 1, 2026 (routine maintenance excluded).
• Carve-out routing — because Cigna chiropractic runs through ASH and UHC through Optum while BCBSMA uses its own WholeHealth Living/Carelon programs, verify the delegated administrator and its specific filing window and auth rules BEFORE submitting; wrong-entity submission and missed treatment-plan/continued-review requirements are the most common MA chiropractic denials. Not legal advice — verify benefits and current rules per payer.

Largely contract/payer-set, not fixed by a single Massachusetts statute. For the dominant Massachusetts commercial payers the common initial-claim filing window is roughly 90-180 days from the date of service, and several of the biggest MA carriers actually run a 90-day clock:

Harvard Pilgrim Health Care / Point32Health requires the claim to be on file within 90 days from the date of service, and Tufts Health Plan (also Point32Health) and many Blue Cross Blue Shield of Massachusetts and UnitedHealthcare commercial products use 90-180 day windows.

When chiropractic is carved out to a delegated administrator (e.g., American Specialty Health for Cigna, or the BCBSMA chiropractic authorization vendor), that administrator’s filing window and rules apply instead. Always confirm the exact deadline in your participating-provider agreement or the payer’s provider manual, since it varies by plan/product.

Massachusetts context: the state’s prompt-pay rule (St. 2000, c. 141, codified around M.G.L. c. 176O and the Division of Insurance regulations) governs how fast the INSURER must pay you, not your submission deadline — a completed (clean) claim must generally be paid, denied with a written reason, or have additional information requested within 45 days of the carrier’s receipt, with interest of 1.5% per month (up to 18%/yr) owed on clean claims not acted on within 45 days.

That is a payment clock, not a filing cutoff; the provider’s submission deadline remains contractual.

Federal limit: generally 12 months (one calendar year) from the date of service to submit an initial Medicare fee-for-service claim. This is set by federal law — Sections 1814(a)(1), 1835(a)(1) and 1842(b)(3)(B) of the Social Security Act and 42 CFR 424.44, as reduced to 12 months by Section 6404 of the Affordable Care Act (effective for services on/after Jan. 1, 2010) — not by Massachusetts.

Limited exceptions exist (e.g., administrative error, retroactive Medicare entitlement). Medicare Advantage plans set their own (often similar ~12-month) contractual deadlines — confirm per plan. Note for chiropractic: UnitedHealthcare/Optum require prior authorization for Medicare-covered chiropractic spinal manipulation for Medicare Advantage members, effective in Massachusetts Jan. 1, 2026 (routine/maintenance care excluded).

MassHealth (Massachusetts Medicaid): generally 90 days from the date of service (or from the date of another insurer’s explanation of benefits when other coverage is involved) to submit an INITIAL claim, per 130 CMR 450.309. A claim that was timely-submitted within the 90-day window may be RESUBMITTED/adjusted up to a FINAL deadline of 12 months from the date of service, extended to 18 months when other insurance or Medicare is involved (the final billing deadline; see 130 CMR 450.323 and the Administrative and Billing Regulations).

A claim missing the 90-day deadline denies with error code 296 (billing deadline exceeded); providers may file a 90-day waiver request for specified circumstances (e.g., retroactive member eligibility, member’s failure to disclose MassHealth coverage) under 130 CMR 450.309(B).

MassHealth managed-care/ACO plans may set their own (often comparable) filing windows — confirm against the live MassHealth regulation, All Provider Bulletins, and the specific plan.

Massachusetts Workers’ Compensation (M.G.L. c. 152, administered by the Department of Industrial Accidents, DIA) does NOT pin a single hard ‘days-from-service’ provider bill-submission cutoff in the billing regulation. Bills are submitted to the insurer on the DIA-prescribed forms (HCFA/CMS-1500 and UB based forms per 452 CMR 6.00) with required documentation.

The principal clock is on the PAYER: under M.G.L. c. 152 ss. 13 and 30 and the DIA rules, the insurer must pay a properly submitted, compensable bill — or give the provider written reasons for nonpayment — within 45 days of receipt of the request for reimbursement, and may not unreasonably delay or repeatedly re-request information.

Separately, the injured worker generally must CLAIM workers’ comp within 4 years of becoming aware the injury/illness is work-related (M.G.L. c. 152, s. 41). Practically: submit bills promptly to the carrier/TPA on the required form and follow the carrier’s instructions; there is no separate fixed statutory provider ‘submit-within-X-days’ deadline, so confirm the carrier’s own timeframe and the current DIA fee schedule/rules.

Massachusetts is a no-fault auto state with mandatory Personal Injury Protection (PIP) under M.G.L. c. 90, s. 34M and 211 CMR 71.00. There is NO fixed ‘submit medical bills within X days’ statutory cutoff for providers, but there ARE hard claimant deadlines: a PIP claim/notice must be presented to the insurer ‘as soon as practicable after the accident’ and ‘in every case, within at least two years from the date of accident.’ PIP pays the first $8,000 of medical expenses/lost wages (medical bills above $2,000 may route to the patient’s health insurer where the patient has health coverage).

The injured person must cooperate, submit to insurer-arranged medical exams (IMEs), and provide records. The insurer must commence payment within 10 days of receiving reasonable proof or give written notice of nonpayment; if benefits due remain unpaid for more than 30 days, the unpaid party (including a provider) is deemed a party to the contract and may sue for the amount due plus costs and reasonable attorney’s fees.

Practical norm: bill PIP promptly with full documentation, watch the 2-year notice/claim window, and expect coordination with Med-Pay/health insurance and the bodily-injury liability claim. Confirm each policy’s terms.
