Missouri sets no deadline, and does not make you exhaust first

The provider complaint process

The department maintains a complaint process for health care providers as a distinct route, not as a footnote to the consumer one. Where a practice cannot get a decision out of an insurance company, or believes a review or appeal was not handled properly, the department is a body it can approach in its own name rather than only through the patient.

Twenty days to respond

The obligation that gives a complaint teeth is a timing one: under Missouri law, health carriers have 20 days to respond to a complaint. That is short enough to be useful on a claim that has been sitting, and it is a date worth recording when the complaint goes in.

Where the rules live

Missouri's framework is spread across statute and regulation, and citing the right piece is what makes an argument read as local rather than generic.

• RSMo 376.1387 — appeals of grievances determined by the director.
• RSMo 376.1389 — expedited grievance review procedure.
• RSMo 376.690 — unanticipated out-of-network care, limits on what may be billed to the patient, and an external arbitration process.
• The Department contracts the independent review organizations that perform the review — currently CIMRO, Maximus Federal Services, and the Kansas Foundation for Medical Care.

Out-of-network claims have their own machinery, and it is fully timed

Where the dispute concerns unanticipated out-of-network care, RSMo 376.690 is the provision to read rather than the general grievance sections — and unlike the external-review side, its deadlines are written out in full. The statute defines unanticipated out-of-network care narrowly: services a patient receives in an IN-network facility from an OUT-of-network professional, from the moment the patient presents with an emergency medical condition until discharge.

1. 1

   Bill within 180 days

   The professional sends the claim to the patient's health carrier within 180 days of delivering the care, on CMS Form 1500 or electronically in the 837 HIPAA format.

2. 2

   The carrier must make an offer in 45 processing days

   Within 45 processing days (as defined in RSMo 376.383) of receiving the claim, the carrier has to offer a reasonable reimbursement — not merely respond.

3. 3

   Know what the offer has to be

   If the professional participates in any of that carrier's commercial networks, the offer must be the amount from the network with the HIGHEST reimbursement.

4. 4

   Sixty days to negotiate

   Declining the initial offer opens a 60-day good-faith negotiation period, counted from the date of that offer.

5. 5

   Then arbitration, on a 120-day notice

   If no agreement is reached, either side initiates arbitration by giving written notice to the director and the other party within 120 days of the end of the negotiation period, stating the billed amount and the date and amount of the offer.

Federal requirements are enforced federally here

Missouri is among the states in which CMS directly enforces federal insurance requirements, together with Alabama, Oklahoma, Tennessee, Texas and Wyoming. The obligation comes from sections 2723 and 2799B-4 of the Public Health Service Act, which require CMS to enforce any provision a state does not substantially enforce, and federal market conduct examinations of issuers are available under 45 CFR 150.313. Where the problem is a federal protection rather than a state one, that is where it is enforced.

No deadline, and no requirement to exhaust first

The Department's own external-review page answers the deadline question in one line: currently, there is no time limitation under Missouri law for filing a request for external review. It adds the practical note that the sooner the Division is contacted, the sooner it can help — but that is advice, not a bar.

The second sentence matters as much. The Department suggests using all appeals and grievance options available through the carrier, but states that you are NOT required to exhaust them before requesting an external review. In most states exhaustion is the gate; in Missouri it is a recommendation.

• No time limitation under Missouri law for filing the request.
• No requirement to exhaust the carrier's internal appeals first.
• No charge to the consumer for the external review.
• Binding on both the consumer and the insurer, subject to limited judicial review.

What the review covers, and who reads it

The Division of Consumer Affairs reviews every external review request and notifies both the covered person and the insurer whether the matter is eligible. Where the dispute turns on a violation of Missouri insurance law or a policy provision, the Department says it will work to resolve that itself rather than referring the case out.

• Eligible grounds: the treatment is not medically necessary, is experimental, is not as effective as other treatments, or a different or lesser level of care is required.
• Services reached: hospitalisation, surgery, mental health and substance abuse treatment, physical therapy, outpatient services, pharmacy, cancer treatments.
• Outside it: workers' compensation, automobile medical payment and liability claims, long-term care, disability income — and any self-funded employer plan.
• The review organization assigns the case to physicians who practise and are certified in the specialty involved, and screens for conflicts with the insurer.
• Both sides then have 15 working days to submit further medical information; an expedited review is answered within 72 hours of the organization receiving everything.

Who actually performs the review

Missouri does not run the review in-house. The Department contracts independent review organizations to perform it, and has listed three under contract: CIMRO, Maximus Federal Services, and the Kansas Foundation for Medical Care. The assignment of a specific case goes to physicians certified in the specialty involved, screened for conflicts with the insurer.

Missouri also gives the rendering provider a reconsideration right with a clock on it. Mo. Rev. Stat. 376.1365 requires the carrier to give the provider who rendered the service an opportunity to request reconsideration of an adverse determination, requires that reconsideration to occur within one working day of the request, and requires it to be conducted between that provider and the reviewer who actually made the adverse determination — or a clinical peer that reviewer designates if the original reviewer is unavailable. Reconsideration is not a prerequisite to a standard or expedited appeal, so asking for it costs nothing.

Behind that, Mo. Rev. Stat. 376.1361 requires the utilization review program to use documented clinical review criteria based on sound clinical evidence and evaluated periodically for ongoing efficacy, requires the medical director administering the program to be a qualified health care professional licensed in Missouri, and requires a licensed clinical peer to evaluate the clinical appropriateness of an adverse determination.

A carrier that breaks the process ends its own gate

The federal rules do more than set clocks. Under 45 CFR 147.136(b)(3)(ii)(F), where an issuer fails to adhere to all of the internal claims and appeals requirements, the claimant is deemed to have exhausted the internal process — and may go straight to external review under the applicable state or federal process without finishing an appeal the carrier is not running properly.

• The exception is narrow: exhaustion is not deemed on de minimis violations that do not cause, and are not likely to cause, prejudice or harm to the claimant.
• Even then, the issuer must show the violation was for good cause or due to matters beyond its control, and that it occurred in an ongoing, good faith exchange of information — 45 CFR 147.136(b)(3)(ii)(F)(2).
• The exception is unavailable altogether where the violation is part of a pattern or practice of violations by the issuer.

For Missouri practices

Reopen the pile before anything else. Because the Department states there is no time limitation and no exhaustion requirement, a Missouri denial that was written off on an assumed four-month clock may still be live — and one still sitting inside the carrier's appeal process can go to external review now rather than after. Then use the route that fits: a carrier that will not decide, or that mishandled an appeal, is a complaint the practice brings directly and the carrier owes a response in 20 days; an out-of-network payment dispute runs through RSMo 376.690 instead.
