Chiropractic insurance billing in Minnesota.

NO auto/PIP medical fee schedule. Minn. Stat. 65B.44, subd. 2 requires reimbursement of ‘all reasonable expenses for necessary’ medical, surgical, dental, chiropractic, and rehabilitative care — a reasonable-and-necessary (usual & customary) standard, NOT a capped fee schedule like workers’ comp.

Unlike WC, no-fault does not tie reimbursement to RBRVS or any maximum-allowable table; 65B.44 also bars insurers and health plans from contracting to provide ‘managed care services to no-fault claimants,’ so PIP claimants cannot be forced into a network.

Disputes over the reasonableness of a charge are resolved by the no-fault arbitration/court process, not by a fee-schedule lookup. (Contrast: WC IS fee-scheduled.)

First-party PIP claim flow:

• The injured insured notifies their own auto insurer of the accident — the plan may require notice within a period of not less than 6 months after the accident, and late notice does NOT defeat benefits unless the insurer shows actual prejudice, and then only to the extent of that prejudice (Minn. Stat. 65B.55, subd. 1).
• Insurer sends an Application for Benefits; the claimant completes it, submits proof of expenses, and must submit to an IME if requested.
• Bills are submitted to the PIP insurer as they come in — in practice treating PROVIDERS bill the PIP carrier directly using the claim number (so accident bills go to PIP, not the patient’s health plan).
• A provider may also stand in the insured’s shoes by assignment (subject to the anti-assignment/Stout timing rule above). Each bill with reasonable proof of loss starts the 30-day pay-or-deny clock (65B.54).

Yes — Minn. Stat. 65B.47 sets a strict order of priority for which insurer pays PIP. General rule: a person injured while occupying a vehicle used in the business of transporting persons or property, or an employee injured in an employer-furnished vehicle, looks first to the security (PIP) covering that vehicle (and otherwise to their own policy).

For other cases (65B.47, subd. 4): an injured person who is an insured looks to their OWN policy first; an occupant who is not otherwise insured looks to the security on the vehicle occupied; and a non-occupant/pedestrian looks to the security covering any involved vehicle, then their own policy.

When two or more obligors are on the same priority level, benefits are payable only ONCE: the insurer billed must process and pay the claim ‘as if wholly responsible,’ then recover pro-rata contribution from the others (65B.47, subd. 5).

The Minnesota Assigned Claims Plan is the backstop where no other PIP security applies.

PIP benefits are OVERDUE if not paid within 30 days after the insurer (reparation obligor) receives reasonable proof of the fact and amount of loss (Minn. Stat. 65B.54, subd. 1). The insurer may instead accumulate claims for periods not exceeding 31 days and pay within 15 days after the accumulation period.

Each itemized bill is treated separately — any portion of a claim supported by reasonable proof (e.g., $100 or more) becomes overdue on its own 30-day clock even if the rest of the claim is unproven — so the 30-day clock can run bill-by-bill as proof of loss is submitted.

Overdue PIP payments bear simple interest at 15% per annum (Minn. Stat. 65B.54, subd. 2) — a steep, automatic statutory rate (vs. WC, which uses the lower 549.09 judgment rate). For claims of $10,000 or less, mandatory binding no-fault arbitration is available as a non-waivable right (Minn.

Stat. 65B.525; MN No-Fault Arbitration Rules), giving providers/insureds a fast, low-cost forum to recover unpaid benefits plus interest. (A 2025-26 legislative proposal to raise that threshold to $20,000 was NOT enacted; $10,000 remains current law.) Minnesota also recognizes a separate first-party insurance bad-faith remedy (Minn.

Stat. 604.18) allowing a taxable award where an insurer lacks a reasonable basis to deny benefits and knew of or recklessly disregarded that lack — capped at the lesser of one-half of the proceeds awarded in excess of the insurer’s pretrial offer or $250,000, plus separately recoverable attorney fees up to $100,000.

No-fault medical expense is ‘incurred’ (and measured by the amount billed, not any negotiated discount) when the patient is billed (Stout v. AMCO Ins. Co., 645 N.W.2d 108 (Minn. 2002)).

If a PIP insurer reduces, partially pays, or denies a bill, the claimant (or a provider holding a valid post-loss assignment) can compel mandatory binding arbitration for claims of $10,000 or less (Minn. Stat. 65B.525) or sue for benefits; overdue amounts carry 15% interest (65B.54, subd. 2).

The IME and the reasonableness/necessity of charges are litigable in that forum. Note on provider standing: a medical provider may pursue a no-fault claim by ASSIGNMENT — but where the auto policy contains an anti-assignment clause, an assignment is valid only AFTER the loss has been incurred (i.e., after the patient has been billed, per Stout), so the timing of the assignment matters.

YES — a mandatory medical fee schedule. Minnesota uses an RBRVS-based maximum-fee system (Minn. Rules 5221.4030 et seq.): maximum fee = CMS relative value unit (RVU) x a Minnesota conversion factor. DLI updates RVUs periodically and adjusts conversion factors annually for services on/after Oct. 1.

For Oct. 1, 2025-Sept. 30, 2026 the medical/surgical conversion factor is $67.29 (it was $67.52 for the prior 10/1/2024-9/30/2025 year). Separate conversion factors/fee schedules apply by category — medical-surgical (5221.4030), pathology/lab ($59.91; 5221.4040), physical medicine & rehab ($60.56; 5221.4050), and CHIROPRACTIC services ($52.15; 5221.4060) for the 2025-26 year.

Inpatient hospital uses a separate DRG-based hospital fee methodology, with outpatient under its own rules. Providers may not balance-bill the employee for compensable care.

Providers must submit itemized charges on the prescribed billing form (CMS-1500 / UB-04 equivalents), accompanied by the medical records/reports that substantiate the nature of the charge and its relationship to the work injury. ELECTRONIC submission is mandated: under Minn.

Stat. 62J.536, health care providers must submit workers’ comp medical bills and supporting documentation electronically using the uniform standards (including the ASC X12N 837 claim and 835 remittance), and DLI’s Work Comp EDI program requires the IAIABC Claims Release R3.1.5 (R3.1) XML format for trading-partner reporting (the ACORD XML format was retired Feb. 9, 2023).

A payer’s 30-day clock does not run until the required substantiating information has been furnished.

Insurer/payer must act ‘as soon as reasonably possible, and no later than 30 calendar days after receiving the bill’: pay the charge (or the portion not denied), OR deny in whole/part with written notice (Minn. Stat. 176.135, subd. 6).

If a charge is denied for missing records or an improper form, the payer must reconsider within 30 calendar days after receiving the additional medical data (subd. 7). A written denial stating the specific basis (non-compensable, excessive, improper form, or missing documentation) must go to the provider, with a copy to the employee.

Medical disputes (denial of authorization, payment, or a charge deemed excessive/not reasonable-and-necessary) are resolved through DLI: the provider or employee files a Medical Request; the matter goes to the commissioner, a settlement/administrative conference, or a compensation judge at the Office of Administrative Hearings (OAH).

Treatment must conform to the treatment parameters in Minn. Rules ch. 5221 (e.g., 5221.6050), which define medical necessity and durational limits; a departure requires justification. Roster/IME and utilization-review-style review apply.

Appeals from a compensation judge go to the Workers’ Compensation Court of Appeals (WCCA) and ultimately the Minnesota Supreme Court.

summary: Minnesota uses an RBRVS-based WC fee schedule with standard CPT, but imposes a unique mandatory coding/payment rule on chiropractic: extraspinal CMT 98943 billed same-day with a spinal CMT code (98940-98942) must carry CPT modifier 51, cutting its RVU by 50% (Minn.

Rules 5221.4061) – a state-imposed reduction not in the national CPT/CMS rules. mandatoryRule: 98943 + spinal CMT (98940-98942) same day => modifier 51 required, -50% RVU on 98943 (Minn. Rules 5221.4061).

summary: Treatment parameters limit passive care (including chiropractic) to 12 calendar weeks, with a conditional additional 12 visits over 12 months under exceptions. cap: Passive treatment (including chiropractic) is limited to 12 calendar weeks, with improvement expected within the first 3-5 treatments (Minn.

Rules ch. 5221). A conditional additional 12 visits over the following 12 months is allowed only with documented functional maintenance, no regularly scheduled visits, a plan to reduce reliance on providers, and active modalities.

Documented departures from the parameters are allowed. authorizationProcess: Care beyond the treatment parameters requires a documented departure justified by the treatment-parameter exceptions; otherwise it is presumed not compensable.

Minnesota Medical Assistance and MinnesotaCare cover chiropractic services for members under age 21, but as of January 1, 2026 adults age 21 and older are generally no longer covered. Before that change, adult coverage typically allowed up to 24 visits per year with prior authorization for additional visits.

Minnesota DCs may generally bill for spinal and extremity adjustment/manipulation, evaluation and management exams, and the taking and interpretation of X-rays. The scope also typically includes physiotherapy modalities such as therapeutic exercise, traction, ultrasound, electrical muscle stimulation, and related rehabilitative procedures.
