Medicaid Eligibility Denied? How to Appeal

Being denied Medicaid eligibility is not the same as being ineligible for Medicaid. Eligibility denials frequently result from income calculation errors, incorrect household composition, documentation failures, or state system errors. Under federal law at 42 CFR Part 431, you have the right to challenge an eligibility denial through a state fair hearing — and many people who appeal successfully obtain coverage. Understanding why the denial occurred is the first step to reversing it.

Why Medicaid Eligibility Is Denied in Error

Income calculation errors are the most common source of wrongful denials. MAGI (Modified Adjusted Gross Income) calculations under ACA Medicaid expansion are governed by federal tax rules — not state-specific methods. Common errors include counting non-countable income (child support received, SSI benefits, workers' compensation, veterans' benefits, gifts), using gross income instead of MAGI-adjusted income, including income of non-household members, applying incorrect household size, or using outdated income figures from a prior year when income has declined.

Documentation and verification failures: States must use electronic data sources to verify eligibility before requesting additional documents from applicants. If the state bypassed this requirement and denied your application solely for lack of documents that could be verified electronically, that is a procedural violation. States must also give applicants a reasonable opportunity to provide requested documentation — denying an application the same day documentation is requested is improper.

System and data errors: Automated eligibility systems produce errors through data matching problems with federal data hubs, Social Security databases, or state records. An eligibility denial produced by automated processing without proper human review may be directly challengeable.

Categorical eligibility errors: States sometimes incorrectly determine an applicant does not fit any Medicaid category. In expansion states, the broad adult coverage category covers adults under 65 with income up to 138% FPL. States failing to consider all applicable categories may be denying eligible applicants.

Residency errors: Medicaid requires state residency, but standards are less stringent than people assume. Experiencing homelessness, living temporarily outside the state, or lacking a fixed address does not automatically create ineligibility. States sometimes apply overly restrictive residency determinations that are challengeable.

How to Appeal

Step 1: Read the denial notice and identify the specific basis

The denial notice must state why the application was denied, the specific eligibility rule applied, and your appeal deadline under 42 CFR § 431.210. Identify whether the denial is based on income, household composition, residency, categorical ineligibility, or documentation. This determines your appeal strategy and evidence needs.

Step 2: Request your complete case file

You have the right to see all documents and data sources the state agency used to deny your application. Request the full case file before your hearing. This often reveals the specific data error or misapplication causing the denial — income figures from wrong tax years, incorrect household members included, or program categories not considered.

Step 3: Gather and calculate your correct income documentation

If the denial is income-based, calculate your own MAGI using IRS Publication 17 or work with a tax preparer. Gather documentation: recent pay stubs, bank statements showing irregular income patterns, tax returns, self-employment records, or benefit award letters. Document non-countable income sources separately and clearly. Document your household composition — only income of members of your tax household counts under MAGI rules.

Step 4: File your state fair hearing request within the deadline

Submit a written request for a state fair hearing to your state Medicaid agency within 90 days of the denial notice (or the shorter deadline stated on your notice). Include your name, the denial date, and a statement that you are appealing the eligibility determination. Courts have been unforgiving about missed appeal deadlines in eligibility cases — file promptly. Send the request in a manner that creates a record: certified mail, fax with confirmation, or online portal with a confirmation number.

Step 5: Prepare a targeted presentation for the hearing

Organize your evidence: documentation of your correct income for each income source; proof of residency (lease, utility bill, shelter letter if homeless); documentation of household composition (birth certificates, tax returns); and any federal data that contradicts the state's eligibility finding. Present your case by pointing to the exact error in the eligibility calculation — be specific and numerical, not general.

Step 6: Apply again while the appeal is pending and seek free assistance

You can reapply for Medicaid while your appeal is pending — if circumstances have changed, a new application may resolve the issue faster. Free help is available from legal aid organizations, ACA Navigators and enrollment assistors, and benefits counselors at community health centers. Contact your state's legal aid organization as early as possible — they handle Medicaid eligibility appeals at no cost.
