Chiropractic insurance billing in Utah.

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 Utah 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 Utah claims are measured against.

A Utah chiropractic or multi-specialty practice spends most of its commercial billing day with: SelectHealth (Intermountain); Regence BlueCross BlueShield of Utah; Molina Healthcare of Utah; UnitedHealthcare; Cigna; Aetna. Each has its own claim portal, fee schedule, and chiropractic medical-policy quirks.

The delegated musculoskeletal/chiropractic network landscape in Utah is split between national carve-out managers and in-house Blues/regional plans.

• American Specialty Health (ASH) is ACTIVE in Utah and administers chiropractic (and often acupuncture/PT) benefits for several national plans — ASH publicly lists Utah among the states where it operates, and it manages chiropractic network, credentialing, treatment-plan/medical-necessity review, and claims for Cigna ASH lines and historically Aetna/Health Net products. When a plan delegates to ASH, network enrollment, treatment-plan prior approval, and claims route to ASH (ashlink.com), NOT to the health plan.
• Optum / Optum Physical Health (UnitedHealth Group) manages chiropractic and outpatient therapy for UnitedHealthcare; for UHC Medicare Advantage, the Medicare-covered chiropractic treatment plan now requires prior authorization reviewed in Optum systems and submitted via the UHC Provider Portal (national MA rollout began Sept 1, 2024; UHC announced in 2026 it is rolling back prior auth on roughly 30% of services, so re-verify current requirements).
• The dominant Utah commercial plans — Select Health (Intermountain) and Regence BlueCross BlueShield of Utah — generally administer chiropractic IN-HOUSE under their own reimbursement/medical-necessity policies rather than carving out to ASH; smaller Utah-based payers (EMI Health, DMBA, PEHP for public employees) likewise tend to manage chiropractic directly. Always verify on the member’s card/portal whether chiropractic is carved out to ASH or Optum, because that determines where authorizations and claims go.

What trips up chiropractic billing in Utah:

• Carve-out routing is a top denial cause — Cigna chiropractic typically runs through ASH (ashlink.com) and UnitedHealthcare through Optum, while Select Health and Regence handle it in-house; sending a claim or treatment-plan auth to the wrong entity gets it bounced. Confirm the delegated administrator on the member’s card before submitting.
• Visit caps / medical-necessity & treatment-plan rules — most Utah commercial plans impose an annual chiropractic visit limit (commonly ~12-20 visits, sometimes a COMBINED cap shared with PT/OT) and require a documented treatment plan, periodic re-evaluation, and a clear shift from active/corrective to ‘maintenance’ care (maintenance is typically non-covered); ASH-administered plans front-load treatment-plan and medical-necessity review.
• Modifiers/coding quirks — expect the AT (active treatment) modifier on Medicare/MA spinal manipulation (98940-98942), correct GA/GY/GZ usage (Medicare/MA covers ONLY manipulation, NOT the DC’s exams, x-rays, or therapy modalities), and proper -25 (separate E/M) and -59/-XU (distinct service) usage; Regence and Select Health both scrutinize manipulation coding/documentation.
• UHC/Optum MA prior auth — the initial evaluation needs no auth, but the treatment plan (number of visits) does; up to ~6 follow-up visits may be auto-approved for a new patient / new condition / 90-day care gap, with anything beyond going to clinical review.
• Utah provider-nondiscrimination law — Utah Code 31A-22-618 bars insurers from refusing to cover a service solely because it is performed by a chiropractor (or other licensed provider) acting within their scope, when that service would be covered if performed by another provider; this is a NONDISCRIMINATION rule, NOT a blanket chiropractic-coverage mandate, so plan-set visit caps, medical-necessity rules, and maintenance exclusions still apply.
• Medicaid scope — verify the member’s Utah Medicaid chiropractic benefit and any visit limits before treating, since coverage is limited and plan-specific.
• Auto/PIP — Utah’s no-fault PIP ($3,000 minimum) makes the patient’s own auto carrier the first payer for accident-related chiropractic; bill PIP monthly with clear documentation of medical necessity and accident causation (insurers heavily scrutinize extended chiropractic care), and move to liens / letters of protection once PIP is exhausted. Not legal advice — verify benefits and current rules per payer.

Largely contract/payer-set, not fixed by Utah statute. The common initial-claim filing window for commercial/private payers runs roughly 90-365 days from the date of service, and Utah’s two dominant commercial Blues-type plans actually sit at the longer end:

Select Health (Intermountain’s plan, the largest Utah commercial payer) and Regence BlueCross BlueShield of Utah both generally allow up to one year (365 days) from the date of service to file. National plans operating in Utah are often shorter — Cigna and many ASH-administered chiropractic lines run ~90-120 days;

UnitedHealthcare commercial commonly ~90-180 days. Always confirm the exact deadline in your participating-provider agreement or the payer’s provider manual, since it can be shorter by plan and product. Utah context: Utah’s prompt-pay / ‘clean claim’ law (Utah Code 31A-26-301.6 and Utah Admin.

Code R590-192) governs how fast the CARRIER must act — a clean claim must generally be paid or denied within 30 days of receipt (electronic) / 45 days (paper), with interest on late payment. That sets the insurer’s PAYMENT clock, not the provider’s SUBMISSION deadline, which 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 the Social Security Act (Section 1842(b)(3)(B)) and CMS, not by Utah. Medicare Advantage plans may set their own (often similar, up to ~12-month) deadlines — confirm per plan.

Note for chiropractic: Medicare/MA covers ONLY manual manipulation of the spine to correct a subluxation (CPT 98940-98942) with the AT modifier for active/corrective care; UnitedHealthcare/Optum Medicare Advantage now requires prior authorization for the Medicare-covered chiropractic treatment plan (the initial evaluation is exempt) — see payerNuance.

Utah Medicaid (Utah Department of Health & Human Services / Medicaid): generally 365 days (one year) from the date of service to submit the INITIAL claim, per the Utah Medicaid Provider Manual, Section I: General Information (‘Time Limit to Submit Medicaid Claims’).

The date of service (the ‘from’ date on the claim) starts the 365-day count. After that period, claims may still be considered only with proof of prior timely submission / a qualifying exception (e.g., retroactive eligibility or third-party-payment circumstances).

Utah Medicaid managed-care plans (e.g., Healthy U / University of Utah Health Plans, Molina Healthcare of Utah, SelectHealth Community Care) generally mirror the 365-day window but apply their own rules — notably, when Medicare or another payer is primary, several plans allow the LATER of 365 days from DOS or ~180 days from the primary payer’s EOB/EOP date.

Confirm with the specific Medicaid plan.

Utah Workers’ Compensation: the provider must submit the bill with supporting documentation to the payor within ONE YEAR of the date of service, per Utah Admin. Code R612-300-7(I)(1) (Labor Commission, Division of Industrial Accidents).

On the payer side, a clean/undisputed bill must be paid within 45 days of submission (R612-300-7(H)(1)). A provider’s written request for re-evaluation of a bill must be submitted within one year of the date of the ORIGINAL payment (R612-300-7(I)(3)), and the payor must pay the additional amount or respond with a specific written explanation within 30 days of receiving that request (R612-300-7(I)(4)).

Utah IS a no-fault / PIP state. Auto policies must carry Personal Injury Protection (PIP) with a statutory minimum of $3,000 in medical benefits per person (Utah Code 31A-22-307); the injured person’s OWN auto insurer pays first regardless of fault.

There is no single fixed ‘days-from-service’ statutory cutoff to submit a bill, but the practical clock is the overdue-payment rule: PIP benefits are payable monthly as expenses are incurred, and a benefit is OVERDUE if not paid within 30 days after the insurer receives reasonable proof of the fact and amount of the expense (Utah Code 31A-22-309); unpaid overdue benefits accrue interest at 1.5% per month.

So providers should submit bills to PIP promptly and monthly so ‘reasonable proof’ is on file. The action to recover PIP benefits is a first-party contract claim subject to a longer limitations period (Utah’s first-party insurance limitation, generally counted from inception of loss).

Once the $3,000 PIP minimum is exhausted (or the statutory injury threshold is met), remaining bills shift to Med-Pay (if purchased), health insurance, or the at-fault driver’s liability carrier (often on a lien / letter-of-protection basis, presented at settlement); the underlying bodily-injury claim is bound by Utah’s general personal-injury statute of limitations.

Confirm each policy’s PIP/Med-Pay proof-of-claim terms.
