Chiropractic insurance billing in Arizona.

No state-mandated auto/MedPay medical fee schedule. MedPay must cover ‘reasonable expenses for necessary medical services.’ What counts as ‘reasonable’ is contested: insurers frequently reduce to a usual-and-customary or network-discounted amount.

One federal decision (Jimenez v. Progressive, D. Ariz. 2020) endorsed paying the discounted amount providers accept as payment in full rather than the full billed charge — but that case arose where the providers had contract/network discount agreements with the insurer, and it is a non-binding district-court ruling.

With no binding fee schedule, ‘reasonableness’ is fact-specific and can be litigated.

No auto-specific ‘prompt-pay statute’ fixes a hard pay-or-deny clock for MedPay the way the workers’-comp and health-claim statutes do. Instead, claim handling is governed generally by Arizona’s Unfair Claim Settlement Practices framework (ARS 20-461 and Ariz.

Admin. Code R20-6-801): typically an insurer should acknowledge a claim within about 10 working days, complete its investigation within about 30 days (or explain in writing why more time is needed, with periodic follow-up updates), and advise acceptance or denial within about 15 working days after receiving a properly executed proof of loss.

These are claims-handling standards, not a guaranteed payment deadline.

There is no PIP multiplier/penalty statute like Pennsylvania’s Act 6 (no automatic treble damages). The Unfair Claim Settlement Practices Act (ARS 20-461, implemented by R20-6-801) is generally enforced administratively by the Department of Insurance and Financial Institutions (DIFI) and, on its own, does not create a private right of action.

The practical leverage for serious mishandling is Arizona’s well-established common-law first-party bad-faith doctrine: an insurer can breach the implied covenant of good faith and fair dealing if it denies or delays a claim without a reasonable basis after an adequate investigation — though an insurer that handles a ‘fairly debatable’ claim with reasonable care and good faith generally is not in bad faith (Zilisch v.

State Farm and related cases). Where bad faith is established, remedies can include consequential damages and, in cases of aggravated conduct, punitive damages.

Because there is no fee schedule and no binding administrative appeal for MedPay reductions, a provider’s recourse to a reduction is generally a contractual/’reasonableness’ dispute rather than a regulatory appeal — and the patient (the insured) usually owns the MedPay contract claim.

A provider’s path to full billed charges is often the third-party liability recovery. Arizona’s health-care-provider lien statute (ARS 33-931 et seq.) lets a licensed provider perfect a lien for customary charges against the patient’s third-party liability recovery; importantly, that lien does NOT reach MedPay, health insurance, or UM/UIM coverage, and roughly one-third of any third-party recovery is exempt from the lien.

So a perfected lien can help preserve customary charges out of a liability settlement, but it is not a tool for recovering MedPay reductions. Documentation supporting medical necessity, and that charges are reasonable/customary in the locality, is the practical key to resisting reductions.

Yes — the Arizona Physicians’ and Pharmaceutical Fee Schedule, adopted by the Industrial Commission of Arizona (ICA) under its statutory authority. It uses an RBRVS-based methodology (relative value units x conversion factor) and is updated annually, effective May 1 (each schedule runs May 1 through April 30).

It sets the maximum allowable reimbursement; chiropractors are covered because ‘physician’ is defined to include chiropractors and naturopaths. A provider and payer may set different rates only by mutual agreement / contract or network.

ARS 23-1062.01 specifies bill content: correct patient demographics and claim number (if known); correct provider information (name, address, phone, federal TIN); appropriate medical coding with dollar amounts, units, and descriptions; clearly printed date(s) of service; and — importantly — legible medical reports for each date of service if the billing is for direct treatment of the injured worker.

A supporting narrative is also generally expected to justify higher-level (level 4/5) E/M codes. Bills are typically submitted on the CMS-1500 form. Missing or illegible chart notes are a common reason bills stall or are denied, so attaching the required documentation at submission matters.

Under ARS 23-1062.01, on an ACCEPTED claim the carrier / self-insured employer / claims-processing representative must determine whether to pay or deny a medical bill (in whole or in part, including the amount to pay) within 30 days — measured from claim acceptance if the bill was received before acceptance, or from receipt of the bill if received after acceptance.

The approved portion must be paid within 30 days after that determination. Late payment accrues interest to the provider at the legal rate from the date payment was due. Separately, the first installment of indemnity/compensation is generally due no later than the 21st day after the ICA notifies the carrier of the claim (ARS 23-1062), unless compensation is denied.

Note a back-end limit on collection: any court action to collect payment of a bill must generally be commenced within 24 months of the date the service was rendered.

All billing denials must be based on ‘reasonable justification’ (ARS 23-1062.01). The injured worker is NOT responsible for any portion of a bill on an accepted claim, and is not responsible for any disputed amount between provider and carrier (no balance billing).

For provider-vs-carrier payment disputes, a carrier MAY establish an internal system for resolving payment disputes and contractual grievances, and the parties are generally expected to resolve fee/payment disagreements between themselves; the ICA does NOT have jurisdiction over disputes about timely payment of billings under contracts between the carrier and the provider, and generally cannot set a fee for a service not covered by the fee schedule.

Underlying compensability disputes (denial of the claim itself, or other Notice of Claim Status determinations) follow a different route: a request for hearing before a Workers’ Compensation Administrative Law Judge at the ICA, generally within the 90-day protest period stated on the notice.

Arizona has no Pennsylvania-style mandatory Utilization Review board for medical-billing disputes.

Arizona Medicaid (AHCCCS) covers chiropractic care; for adults it generally allows up to about 20 medically necessary visits per year when ordered by a primary care provider, while children under 21 receive broader coverage under EPSDT.

The chiropractor must be AHCCCS-enrolled and documentation of medical necessity is typically required for additional visits.

Under A.R.S. 32-925, Arizona DCs are a portal-of-entry provider who may generally bill for spinal and joint adjustments, physical and clinical examinations, and diagnostic X-rays to determine the propriety of chiropractic care. Physical-medicine modalities and therapeutic procedures (physiotherapy) are specialty areas that typically require additional board certification, and DCs may not prescribe drugs or perform surgery.
