Chiropractic insurance billing in Alaska.

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 Alaska are processed by Noridian Healthcare Solutions (JF) — its Local Coverage Determination and documentation expectations (and its audits of the AT modifier and medical necessity) are the ones your Alaska claims are measured against.

A Alaska chiropractic or multi-specialty practice spends most of its commercial billing day with: Premera Blue Cross Blue Shield of Alaska; Moda Health Plan; Aetna; UnitedHealthcare; Cigna Health & Life. Each has its own claim portal, fee schedule, and chiropractic medical-policy quirks.

For chiropractic/physical-medicine benefits, the key delegated network manager active in Alaska is Optum Physical Health (formerly OptumHealth Physical Health / ACN), which administers UnitedHealthcare’s chiropractic and outpatient-therapy network and utilization management; for UHC plans, the treatment-plan prior authorization (number of visits) is reviewed by Optum Physical Health (provider portal: myoptumhealthphysicalhealth.com), and for UHC Medicare Advantage, prior authorization for chiropractic has been required since 9/1/2024 with Optum delegated for the medical-necessity review (initial eval is exempt; first 6 visits within 8 weeks generally pass without clinical review under 2025 rules).

Premera Blue Cross Blue Shield of Alaska (the dominant commercial carrier) does NOT delegate chiropractic to American Specialty Health (ASH); Premera contracts chiropractors directly and routes utilization management through eviCore by Evernorth (outpatient rehabilitation management) and Carelon Medical Benefits Management for select services.

American Specialty Health (ASH/ASHLink) is the national delegated chiro/acupuncture/PT network for carriers such as Aetna, Cigna, and several Anthem/Blue plans, and it can govern claims/auths where those carriers’ members are treated in Alaska, but ASH is not a confirmed dominant Alaska-market delegate the way Optum (for UHC) is.

Bottom line: verify the member’s specific plan, because where the claim and authorization go (direct to the carrier vs. Optum Physical Health vs. eviCore/Carelon vs. ASH) depends on the carrier and product. Confirm current arrangements at point of service.

Chiropractic billing in Alaska is dominated by Premera Blue Cross Blue Shield of Alaska and UnitedHealthcare/Optum, and the recurring pitfalls are medical-necessity and treatment-plan/authorization rules rather than a state chiropractic mandate.

Premera covers chiropractic manipulative treatment (CMT) only when medically necessary for a diagnosed neuromuscular condition expected to improve/resolve with standard care (manual or instrument-assisted manipulation only); wellness, preventive, and maintenance therapy are typically not covered, and active-care documentation, a clear treatment plan, and measurable functional improvement (to avoid ‘maintenance’ denials) are essential.

Premera routes outpatient rehab/physical-medicine prior authorization through eviCore by Evernorth and certain services through Carelon, so chiropractors providing therapy/PT-style services (modalities, therapeutic exercise) frequently hit prior-auth and visit-cap requirements distinct from the manipulation benefit.

For UnitedHealthcare, Optum Physical Health requires a prior-authorized treatment plan specifying the number of visits (initial evaluation exempt; up to 6 visits within 8 weeks generally auto-approved under 2025 rules), and UHC Medicare Advantage now requires chiropractic prior auth.

Common modifier/coverage traps: appending the AT (active treatment) modifier on CMT for Medicare/MA payers and avoiding maintenance billing; correct CMT region coding (98940-98942) with a payable spinal diagnosis; and not over-billing modalities/exams without supporting documentation.

Alaska does NOT impose a broad state-mandated commercial chiropractic benefit, so visit caps and necessity rules are payer/plan-specific (Premera commercial plans commonly cap CMT visits per year per plan design). Note for context:

Alaska Medicaid covers chiropractic only narrowly (children under 21 limited to 12 spinal manipulations and one chiropractic X-ray per calendar year, with service authorization and referral required for recipients under age 6; adult coverage is limited to those with Medicare Part B).

Always verify visit limits, modifier rules, and the delegated administrator per the member’s specific plan.

Commercial/private-payer initial-claim windows in Alaska are set by the provider contract or payer policy, not by a single state statute, so confirm per payer and per contract. The common range runs roughly 90-180 days, though several major payers allow up to 365 days.

Notably, Premera Blue Cross Blue Shield of Alaska (the dominant commercial carrier) prefers claims within 60 calendar days but accepts them no later than 365 calendar days from the date of service; claims received after 12 months are denied with no member liability.

Alaska has no general all-payer prompt-pay/clean-claim statute mandating a specific filing deadline, but Premera applies Washington’s prompt-pay standard (pay/deny 95% of clean claims within 30 days of receipt, with 15% annual interest on late clean claims).

As of 2025-2026; verify each payer’s current provider manual.

12 months (one calendar year) from the date of service. This is a federal rule (42 CFR 424.44; Social Security Act 1842(b)(3)), effective for services on or after January 1, 2010, and applies in Alaska via the Part A/B MAC (Noridian, Jurisdiction F).

Claims received after 12 months are denied as untimely and that untimeliness determination is generally not appealable; only narrow CMS exceptions apply (e.g., administrative error, retroactive eligibility). Stated plainly: file within 12 months of DOS.

12 months from the date of service. Alaska Medicaid (Department of Health; fiscal agent Conduent/Gainwell) requires all claims to be filed within 12 months of the date services were provided, including claims first billed to a third-party carrier (attach the third-party EOB; the 12-month clock still runs from the date of service).

Claims received after the period require documentation proving timely filing or a qualifying extension condition. Adjustment requests must be submitted within 60 days of the payment date, or within 12 months of the date of service if additional amounts are owed.

Alaska’s WC rules do not set a single ‘submit the bill within X days of treatment or the claim is denied’ deadline the way commercial payers do; instead, two regulatory timers govern.

• 8 AAC 45.086: a provider who renders services must serve a report on the employer no later than 14 days after each service (treatments within a 14-day span may be combined on one form), and the board may, in its discretion, deny the provider’s claim for payment if this is not met.
• 8 AAC 45.082(d): medical bills are due and payable no later than 30 days after the employer receives the provider’s bill plus the required completed report; if the employer controverts or short-pays, it must notify the employee and provider in writing within that 30 days. Practically, bills should be submitted promptly with the required physician’s report, and the overall right to benefits is tied to the worker’s underlying claim and the Act’s notice/limitation periods. Confirm current text with the Alaska Workers’ Compensation Board, as the medical regulations and fee schedule are periodically amended.

Alaska is an at-fault (tort) state, not a no-fault state, and PIP is NOT required (PIP/Med-Pay are optional first-party coverages, commonly around $10,000 for medical/lost income). There is NO fixed statutory deadline for submitting medical bills or notice to an auto PIP/Med-Pay insurer; submission timing and proof-of-loss requirements are governed by the individual auto policy contract, so the practical norm is to bill promptly per the policy’s terms (often ‘as soon as reasonably possible’/proof of loss within a stated period).

The underlying liability/bodily-injury claim is bound by Alaska’s 2-year personal-injury statute of limitations (AS 09.10.070). Confirm the specific PIP/Med-Pay endorsement terms with the auto carrier.
