Missouri Health Insurance Appeals and Grievances

What is an internal appeal?

An internal appeal asks the health carrier to reconsider an adverse determination about coverage, payment, or utilization review. Missouri law requires carriers to describe appeal rights in member materials (RSMo § 376.1372).

This is different from external review, where DCI assigns an independent reviewer after you and the carrier disagree.

General walkthrough: Appeals roadmap. Missouri specifics below.

Missouri appeal timelines

How many appeal levels?

According to DCI consumer guidance (DCI — health insurance appeals):

• Group health plans: usually two levels of appeal with the carrier (first-level and second-level grievance)
• Individual plans: often one or two levels—check your policy or certificate of coverage

Federal timelines (many ACA plans)

For plans subject to Affordable Care Act standards, internal appeal decisions are often due within:

• 30 calendar days for pre-service (authorization) denials
• 60 calendar days for post-service (payment) denials
• Expedited appeals when delay would seriously jeopardize life, health, or ability to regain maximum function

If the carrier misses these deadlines without your agreement to extend, you may be able to go straight to external review under federal rules.

Utilization review appeals

Adverse determinations under § 376.1363 must include instructions for appeal or reconsideration in the written notice (§ 376.1363.5).

How to file

1. Read the adverse determination for the appeal deadline, phone number, and required format.
2. Submit a written appeal to the carrier with medical records and a provider letter.
3. Request expedited review if urgent harm is likely.
4. Keep copies of everything submitted and the date sent.

• Clinical records and the carrier's clinical review criteria (posted online under § 376.1372)
• Peer-reviewed literature for experimental/investigational disputes

Medicaid appeals

MO HealthNet managed care requires an MCO appeal before a state fair hearing in most cases:

• MCO appeal: 60 calendar days from the Notice of Adverse Benefit Determination (federal Medicaid standard)
• State fair hearing: within 90 calendar daysof the MCO's written Notice of Appeal Resolution; call 800-392-2161 for help (MO HealthNet — appeals)
• Final agency action often within 90 days of the hearing request
• To keep services during appeal, request a fair hearing within 10 calendar days of the MCO resolution notice when reduction or termination is at issue

DCI external review does not replace MO HealthNet fair hearings.

After internal appeal

If the plan upholds the denial, request external review through DCI—generally within 4 months of the adverse determination under federal Marketplace rules. DCI suggests using internal appeals first but does not require exhaustion.
