Wyoming Health Insurance Appeals and Grievances

Chapter 63—30-day internal filing, 45-day decision, path to DOI-registered IRO.

What is an internal appeal?

An internal appeal (internal review) asks the health insurer to reconsider an adverse benefit determination—when the plan denies a claim or service as not medically necessary or on a similar clinical basis.

Wyoming disability and health policies must include internal review procedures under W.S. 26-40-201 and Insurance Department Regulation Chapter 63. You must generally complete internal review before external review for medical-necessity denials.

General walkthrough: Appeals roadmap.

Wyoming appeal timelines

Wyoming medical-necessity notices (Chapter 63)

When a claim is denied as not medically necessary, the insurer must notify you in writing with:

  • Right to internal review—request generally due within 30 days of the denial notice (Wyo. Ins. Dept. Reg. § 63-5)
  • Right to external review by a DOI-registered IRO after internal review—generally within 120 days of the final internal denial notice
  • Right to expedited internal and external review when delay would seriously jeopardize life, health, or ability to regain maximum function—decision within 72 hours

Typical internal review timing

  • Standard internal review: insurer decision often within 45 days of receiving your request
  • Expedited internal review: within 72 hours when clinically appropriate
  • Deemed exhaustion: if the insurer does not issue a final written decision within 45 days (and you have not agreed to an extension), you may be able to proceed to external review

Federal internal appeal standards (many ACA and group plans)

For many HealthCare.gov and employer plans, federal law also requires appeal rights—often up to 180 days to file, 30-day pre-service and 60-day post-service decisions, and 72-hour urgent appeals. Use the deadline on your denial letter; if state and federal deadlines differ, meet the earlier one.

How to file

  1. Read the denial for internal review instructions and deadlines (often 30 days under Wyoming rules).
  2. Submit a written request to the address on your denial—include member ID, date of service, and why the care is medically necessary.
  3. Ask for expedited review if delay would seriously jeopardize life or health.
  4. Request the reviewing clinician's credentials and signed opinion if offered in your notice.
  5. Keep copies of everything sent and the date sent.

Evidence that helps

  • Treating clinician letter on medical necessity
  • Insurer's clinical criteria (request in writing if not provided)
  • Peer-reviewed literature for experimental or investigational disputes

Medicaid appeals

Wyoming Medicaid uses a separate administrative hearing process—not commercial IRO external review:

  • Eligibility denials, changes, or terminations: request an administrative hearing within 30 days of your Notice of Adverse Action (instructions on the back of the notice)
  • Office of Administrative Hearings (OAH): oah.wyo.gov
  • Medicaid help line: 855-294-2127 (TTY 855-329-5204)
  • Provider claim denials may follow Medicaid appeal procedures in the provider manual—members should contact WYhealth or their care manager for service disputes

After internal appeal

If you receive a final denial with external review rights for a medical-necessity dispute, submit a written external review request to your insurer within 120 days (DOI — independent review).
