Medicaid Claim Denied? Your State Fair Hearing Rights and How to Use Them

Medicaid covers more than 90 million Americans — low-income adults, children, pregnant women, seniors, and people with disabilities — through a joint federal-state program. Despite its broad mandate, Medicaid denials are extremely common, and most beneficiaries do not know they have a federally guaranteed right to challenge every denial through a process called a state fair hearing. If your Medicaid claim was denied, this guide explains your rights and how to fight back.

Why Medicaid Denials Happen

Medical necessity denials occur when a state or managed care organization (MCO) determines that a treatment does not meet its clinical criteria, even if your doctor strongly recommends it. Medicaid MCOs apply internal clinical guidelines that may be more restrictive than generally accepted medical standards.

Prior Authorization Denied: How to Appeal" class="auto-link">Prior authorization denials block access to medications, procedures, and services when required pre-approval was not obtained or was denied. Under 42 CFR Part 438, Medicaid MCOs must use evidence-based clinical criteria for PA decisions and cannot impose barriers resulting in less access than fee-for-service Medicaid.

Managed care disputes: Approximately 70 percent of all Medicaid enrollees are in managed care plans that have their own PA criteria, formularies, and level-of-care requirements. MCO denials are appealable through both the MCO's internal process and a state fair hearing.

Eligibility-related denials may claim you no longer qualify for coverage based on income calculation errors, incorrect household composition, or documentation failures — many of which are procedural errors rather than genuine ineligibility.

Administrative denials cite missing documentation, billing codes, or procedural issues — often curable with corrected information.

How to Appeal

Step 1: Read your Notice of Adverse Benefit Determination carefully

Under 42 CFR § 431.210, every adverse action notice must state the specific reason for the denial, the specific regulation supporting the action, and your right to appeal and request a fair hearing. Note the exact denial reason — it determines your appeal strategy and evidence needs.

Step 2: File for continuation of benefits immediately if you are receiving ongoing services

Under 42 CFR § 431.230, if your Medicaid benefits are being reduced, terminated, or suspended, you have the right to continue receiving your current level of benefits while your appeal is pending — as long as you file your fair hearing request before the effective date of the action. This "aid pending hearing" right is critical for beneficiaries facing reduction of ongoing services. Request it explicitly in your fair hearing request.

Step 3: File an internal appeal with your Medicaid MCO

For managed care members, file an internal MCO appeal within 60 days of the denial notice. For urgent situations, request expedited review — the MCO must decide within 72 hours. Submit a detailed appeal with your treating physician's letter of medical necessity, current treatment records, and clinical guidelines from professional medical societies supporting the requested service.

Step 4: Request a state fair hearing under 42 CFR § 431.220

Every Medicaid beneficiary has the federally guaranteed right to a state fair hearing when a state agency or MCO takes an adverse action. The deadline to request a hearing is 90 days from the date of the denial notice. Submit your request in writing to your state Medicaid agency — not your MCO. Include your name, Medicaid ID number, the specific service denied, the denial date, and a statement requesting a fair hearing. After you request a hearing, the state must give you at least 10 days' advance notice of the hearing date and access to your complete case file.

Step 5: Build your hearing record with strong clinical documentation

Your hearing record should include: a letter from your treating physician explaining the medical necessity of the denied service in detail, citing clinical guidelines from professional medical societies; a copy of the specific clinical criteria the MCO used to deny your claim (request this — you are entitled to it); evidence that the criteria applied are inconsistent with generally accepted medical standards; and any prior authorization approvals for the same or similar treatment.

Step 6: Escalate after the fair hearing if necessary

If you lose at the state fair hearing level, you have the right to seek judicial review in state court. For Medicaid managed care denials, file a complaint with CMS (cms.gov), which has oversight authority over state Medicaid programs. Legal aid organizations and the National Health Law Program (NHeLP) may provide free legal assistance for complex Medicaid appeals.

What to Include in Your Appeal

• Notice of Adverse Benefit Determination with the specific reason and regulation cited
• Treating physician's letter of medical necessity citing professional society guidelines
• The MCO's clinical criteria used to deny the claim (request this in your appeal)
• Evidence of prior authorization approvals for the same or similar treatment in the past
• Request for continuation of benefits if applicable (must be filed before the effective date of any service reduction)
