Chiropractic insurance billing in Alaska.

Original Medicare Part B covers medically necessary manual spinal manipulation to correct a subluxation (CPT 98940 to 98942). Use the AT modifier for active or corrective treatment; the modifier alone does not establish medical necessity.

For a usually covered service expected to be denied in a particular case, such as spinal manipulation that has become maintenance care, a valid ABN is required before treatment to transfer potential financial liability to the patient. Exams, X-rays and therapies performed by a chiropractor are statutorily excluded from this benefit; an ABN for those services is voluntary. Medicare Advantage uses separate plan coverage and notice procedures, not the Original Medicare ABN. See CMS guidance on advance notices and our chiropractic Medicare billing guide.

Original Medicare Part B claims in Alaska are processed by Noridian Healthcare Solutions (JF). Check its applicable Local Coverage Determination and documentation requirements for the date of service.

Carriers listed for Alaska include Premera Blue Cross Blue Shield of Alaska; Moda Health Plan; Aetna; UnitedHealthcare; Cigna Health & Life. Check the member’s product, network, claim destination and applicable chiropractic policy.

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, the October 1, 2026 reduction list removes prior authorization for spinal CMT codes 98940-98942, subject to plan-specific exceptions. Therapy and commercial requirements remain code- and product-specific; check the portal for the member, especially a D-SNP, whose separate reduction table does not list these CMT codes.

Premera publishes eviCore by Evernorth review for outpatient rehabilitation and Carelon Medical Benefits Management review for select services; use the member’s product and the service code to choose the correct route.

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 alongside Alaska’s product-specific chiropractic protections.

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 products still subject to Optum Physical Health authorization, submit a treatment plan specifying the number of visits (initial evaluation exempt; up to 6 visits within 8 weeks covered without clinical review under the earlier 2025 MA rules).

UHC’s MA code list removes prior authorization for spinal CMT 98940-98942 effective October 1, 2026, subject to plan-specific exceptions. The separate D-SNP list does not include these CMT removals. Check the member’s product and CPT; commercial and other therapy authorization rules remain product- and code-specific.

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’s 2026 EHB benchmark includes 20 chiropractic visits per year for applicable individual and small-group plans, and AS 21.86.075 protects HMO enrollees’ access to licensed chiropractors. Apply the member’s benefit limits and the requirements for that plan. Note for context:

Alaska Medicaid covers chiropractic only narrowly (children under 21 ordinarily limited to 12 spinal manipulations and one chiropractic X-ray per calendar year, with medically necessary additional services available through the EPSDT authorization process, 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.

Provider filing is separate from Alaska’s health-insurer payment rule in AS 21.36.495; Premera also publishes its own clean-claim 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, under 7 AAC 145.005(c). Retain the third-party EOB for coordinated claims. The regulation provides a specific later-established-eligibility extension; 7 AAC 105.270(b) also addresses department error, timely-but-unprocessed claims and referenced good cause in a filing-deadline appeal. For payment adjustments, use the current provider-manual procedure; a provider first-level payment appeal under 7 AAC 105.270 is a separate process due within 180 days of the disputed remittance advice.

Alaska WC medical bills must be submitted within 180 days after the later of the service date or the provider’s knowledge that the injury or illness was employment-related (AS 23.30.097(h)); a payment appeal must be made within 60 days after denial (AS 23.30.097(i)). Two additional regulatory timers govern reports and payment.

• 8 AAC 45.086: a provider who renders services must serve a report on the employer no later than 14 days after each service, 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 (optional MedPay covers eligible medical expenses up to the purchased policy limit). 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.
