Chiropractic insurance billing in Nebraska.

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 Nebraska are processed by WPS Government Health Administrators (J5) — its Local Coverage Determination and documentation expectations (and its audits of the AT modifier and medical necessity) are the ones your Nebraska claims are measured against.

A Nebraska chiropractic or multi-specialty practice spends most of its commercial billing day with: Blue Cross and Blue Shield of Nebraska; UnitedHealthcare; Medica; Aetna; Cigna; Ambetter (Celtic/Nebraska Total Care). Each has its own claim portal, fee schedule, and chiropractic medical-policy quirks.

Where chiropractic claims and authorizations go in Nebraska depends heavily on the plan, and it is NOT uniform:

• Blue Cross and Blue Shield of Nebraska (BCBSNE) — the dominant Nebraska commercial carrier — generally manages chiropractic/physical-medicine benefits IN-HOUSE rather than delegating to a third-party specialty network; claims, prior authorizations, and credentialing for BCBSNE commercial members go to BCBSNE under its own medical policies and timely-filing rules.
• American Specialty Health (ASH) is the national delegated chiropractic/PT/acupuncture network manager that contracts with Aetna, Cigna, and various Anthem/Elevance plans — for those carriers, chiropractic network management, authorization/clinical review, and often claims processing can be carved out to ASH (ASHLink). Whether a given Aetna or Cigna Nebraska plan delegates chiropractic to ASH is region/product-specific and is NOT guaranteed, so ALWAYS verify on the member’s ID card/portal whether chiropractic is administered by ASH or by the health plan directly before sending claims or auths.
• UnitedHealthcare delegates chiropractic/physical-health network management and utilization review to OPTUM (Optum Physical Health); for UHC commercial/MA, chiropractic auths and the Medicare-covered spinal-manipulation treatment-plan/visit review route through Optum (entered via the UnitedHealthcare Provider Portal), with prior-auth requirements rolling out by state — verify current Nebraska status.
• On the Medicaid side, the three Heritage Health MCOs (Nebraska Total Care, Healthy Blue, Molina) each manage chiropractic under their own provider manuals and may use their own UM vendors. The single biggest routing rule in Nebraska: confirm the administrator per MEMBER — for the largest commercial book (BCBSNE) it is typically the plan itself, for UnitedHealthcare it is Optum, and for Aetna/Cigna it may be ASH.

What actually trips up chiropractic billing in Nebraska:

• Nebraska has a CHIROPRACTIC NON-DISCRIMINATION / freedom-of-choice mandate — Neb. Rev. Stat. 44-513 provides that when an insurance policy covers a service that may legally be performed by a licensed chiropractor, the insurer must reimburse for that service whether it is performed by a licensed medical doctor OR by a licensed chiropractor (the patient/provider cannot be denied reimbursement solely because a chiropractor rendered the otherwise-covered service). IMPORTANT LIMITS: it is a reimbursement-non-discrimination rule, NOT a guarantee of unlimited visits and (per the statute’s own annotations/case law) it does NOT force identical copays for different provider types; it expressly does not bar preferred-provider/PPO arrangements (44-4101 to 44-4113); and it does not override medical-necessity or visit-cap rules. It applies to regulated health insurance, not to workers’ comp or auto medical-payment coverage.
• BCBSNE utilization management is the practical gatekeeper for the largest commercial book — expect medical-necessity documentation, a treatment plan with functional goals, periodic re-evaluation, visit/therapy-unit limits per the member’s benefit, and exclusion of maintenance/wellness care; verify the current visit allowance and any prior-auth threshold in the member’s specific benefit document and the BCBSNE medical policies.
• Aetna/Cigna via ASH — when chiropractic is delegated to ASH, expect ASH’s own clinical submission/treatment-plan process, authorization rules, and claims routing (ASHLink); billing to the health plan instead of ASH is a common cause of denials.
• UnitedHealthcare/Optum — Medicare-covered manipulation (98940-98942 with the AT modifier) is reviewed/authorized through Optum for the treatment plan/visit count (initial eval typically exempt); maintenance care is excluded.
• Medicare/MA coverage limits — traditional Medicare and MA cover only manual spinal manipulation to correct a subluxation (98940-98942) and statutorily exclude chiropractor-performed exams, x-rays, and therapies; use the AT modifier for active/corrective treatment and GA/GY/GZ appropriately.
• Nebraska Medicaid — chiropractic IS a covered service (471 NAC ch. 5), but coverage is LIMITED (certain spinal x-rays, manual spinal manipulation, certain E/M, traction, electrical stimulation, ultrasound, and certain therapeutic procedures), some services require prior authorization, and you bill the member’s Heritage Health MCO (Nebraska Total Care, Healthy Blue, or Molina) to its own rules and 180-day deadline.
• Workers’ comp and auto — WC pays per the Nebraska WC Court fee schedule (lower of fee schedule or billed charge), and auto MedPay/liability is policy- and settlement-driven; both sit OUTSIDE the 44-513 mandate, so the chiropractic non-discrimination rule does not apply there. Verify current rules per payer; not legal advice.

Largely contract/payer-set — the exact initial-claim filing window lives in your participating-provider agreement and the payer’s provider manual, not in Nebraska statute. The common commercial/PPO range runs roughly 90 to 180 days from the date of service, though some plans allow up to a year and tightly-managed networks can be shorter.

For Nebraska’s dominant commercial payer, Blue Cross and Blue Shield of Nebraska (BCBSNE), the standard participating-provider window is 120 DAYS from the date of service to file a clean claim (policy GP-X-046, ‘Timely Filing Limit’), unless the provider agreement specifies otherwise; for coordination of benefits, BCBSNE counts 120 days from the date on the primary payer’s EOB, and adjustments/revisions to a timely-filed claim are not accepted more than 12 months from the last date of adjudication.

Nebraska does NOT have a broad statutory ‘submit within X days’ deadline that resets your submission clock; Nebraska’s clean-claim/prompt-pay expectations (Neb. Rev. Stat. 44-8101 et seq., the Health Care Prompt Payment Act, and Dept. of Insurance oversight) govern how fast the PAYER must pay a clean claim, not how long you have to file.

Bottom line: use the deadline in your specific contract/provider manual, treat ~90-180 days (and BCBSNE’s 120 days) as the planning default, and verify per payer. As of 2025-2026.

Federal limit: generally 12 months (one calendar year) from the date of service to submit an initial Medicare fee-for-service claim. Set by the Social Security Act (Sec. 1842(b)(3)) and CMS, not by Nebraska. Nebraska’s Medicare Part A/B claims are processed by the MAC for Jurisdiction 5 (Wisconsin Physicians Service / WPS Government Health Administrators).

Medicare Advantage plans set their own contractual deadlines (often similar, frequently up to ~12 months, sometimes shorter) — confirm per plan.

Nebraska Medicaid (fee-for-service): the timely-filing limit is 6 MONTHS (about 180 days) from the date of service — the claim must be RECEIVED by the Department within six months from the date of service, per 471 Neb. Admin. Code ch. 3, 003 (‘Approval and Payment’) and the DHHS Medicaid Provider Claims Processing FAQ. Key wrinkles in the same rule:

• the Department MAY pay a claim received after six months if the provider documents that the delay was ‘beyond the provider’s control’;
• for Medicare/secondary-payer (crossover/COB) claims, the Medicaid portion must be submitted within six months from the date of the MEDICARE remittance advice;
• an ABSOLUTE outer limit applies — the Department will NOT pay claims received more than TWO YEARS after the date of service except as specified in the chapter; and
• claim ADJUSTMENTS are restricted to a maximum of 90 DAYS from the date on the Medicaid remittance advice (with limited exceptions, e.g. third-party-resource denials, or approved extenuating circumstances). IMPORTANT: most Nebraska Medicaid members are enrolled in HERITAGE HEALTH managed care, served by three statewide MCOs — Nebraska Total Care (Centene), Healthy Blue (Elevance/BCBSNE-Healthy Blue), and Molina Healthcare of Nebraska (Molina replaced UnitedHealthcare Community Plan effective Jan. 1, 2024). The MCOs set their own initial-filing windows, commonly 180 DAYS from the date of service (Nebraska Total Care, for example, requires claims within 180 calendar days). Always bill to the member’s specific Heritage Health plan deadline when the member is in managed care, not the FFS rule.

Nebraska Workers’ Comp does NOT set a single fixed ‘provider must submit the bill within X days’ statutory deadline, but unlike many states Nebraska DOES have a mandatory medical fee schedule — the Nebraska Workers’ Compensation Court Schedule of Fees for Medical Services, updated annually (current edition effective Jan. 1, 2026; reimbursement is generally the lower of the fee-schedule amount or the provider’s billed charge), adopted under Neb.

Rev. Stat. 48-120 and the Court’s Rules of Procedure. Practically: bill the carrier/employer promptly on the standard form (CMS-1500/UB-04, plus supporting documentation) at the fee-schedule rate, because Nebraska has not issued e-billing rules and the carrier’s payment obligation runs off your submission.

Note a related provider reporting duty: the treating physician’s first report is generally to be furnished to the employer within 14 days following the first treatment. The high-stakes clock is the underlying CLAIM deadline, not bill submission: under Neb.

Rev. Stat. 48-137, a claim for compensation is forever barred unless a petition is filed within TWO YEARS of the accident (or within two years of the last payment of compensation), with tolling if the employer failed to file a required injury report or for legal disability — if the injury is found non-compensable, the WC carrier is not the payer.

Confirm current fee-schedule and rule text on the Nebraska Workers’ Compensation Court site (newcc.gov / wcc.ne.gov) and bill promptly.

Nebraska is an AT-FAULT (tort) state, NOT a no-fault/PIP state, and Nebraska law does NOT impose a fixed statutory deadline for a provider to submit medical bills to an auto insurer. PIP is not mandatory in Nebraska; auto policies instead commonly offer optional first-party Medical Payments (MedPay) coverage (and some carriers offer optional PIP), which pays accident-related medical bills regardless of fault up to the limit. Nebraska’s minimum bodily-injury liability limits are $25,000 per person / $50,000 per accident. Practical reality:

• For MedPay/first-party (or optional PIP) claims, submission timing and any notice/proof-of-loss requirements are set by the auto POLICY, not statute — read the policy and submit promptly.
• For third-party/liability (the at-fault driver’s bodily-injury coverage), the provider is usually paid out of the injured patient’s settlement, not by direct billing; the patient’s underlying personal-injury claim is governed by Nebraska’s 4-YEAR statute of limitations for personal injury (Neb. Rev. Stat. 25-207).
• When the patient also has health insurance, coordinate carefully — the health plan’s own timely-filing clock (above) keeps running while an auto/MedPay claim is pending, so don’t let the health-plan deadline lapse waiting on the auto carrier. No fixed state bill-submission deadline exists; use the policy terms and protect the health-plan and liability-claim clocks.
