Washington Apple Health Denied? How to Appeal Your Medicaid Claim

Washington State's Medicaid program is called Apple Health. It's administered by the Washington State Health Care Authority (HCA) and covers over 2 million residents, including children, adults, seniors, people with disabilities, and undocumented children under the Apple Health for Kids program. If your Apple Health claim or Prior Authorization Denied: How to Appeal" class="auto-link">prior authorization was denied, you have the right to appeal — and Washington's system provides multiple paths to challenge a denial.

How Washington Apple Health Is Structured

Most Apple Health enrollees are in a managed care organization (MCO). Apple Health MCOs include:

• Amerigroup Washington (Elevance)
• Community Health Plan of Washington
• Coordinated Care (Centene)
• Molina Healthcare of Washington
• Premera Blue Cross
• United Healthcare Community Plan of Washington

Some enrollees receive care through Apple Health fee-for-service, including individuals with certain complex needs or those in counties without MCO contracts.

Washington also has the Aging and Long-Term Support Administration (ALTSA), which manages home and community-based waiver programs like the Community First Choice (CFC) program, the COPES waiver (home care for adults), and the CHORE services program.

Children not eligible for full Medicaid may qualify for Apple Health for Kids — the state's CHIP equivalent.

Why Apple Health Claims Get Denied

Common reasons include:

• Medical necessity: The MCO's utilization management team determines the service doesn't meet its criteria
• Prior authorization denied: Required preapproval was not obtained or was refused
• Out-of-network care: Service received from a provider outside the MCO network
• Documentation gaps: Insufficient clinical records from the provider
• Benefit not covered: The service is excluded from Apple Health's benefit package
• Eligibility lapse: Your coverage was not renewed during the annual redetermination

Step 1 — File a Grievance or Appeal With Your MCO

When your Apple Health MCO denies a covered service, it must send you an Adverse Benefit Determination (ABD) notice. You have 60 days to file an internal appeal.

Submit your appeal in writing and include:

• The denial letter
• Doctor's clinical notes and letters of medical necessity
• Specialist evaluations or test results
• Relevant clinical guidelines

Request an expedited appeal if the situation is urgent — the MCO must respond within 72 hours.

Standard appeals must be resolved within 30 days. If the MCO upholds its denial, you can request a state administrative hearing.

Step 2 — Request an Apple Health Administrative Hearing

Washington Apple Health enrollees have the right to an Administrative Hearing before the Office of Administrative Hearings (OAH). This is a formal state hearing where an administrative law judge (ALJ) reviews your case.

To request a hearing, contact:

• HCA Apple Health Customer Service: 1-800-562-3022
• Or submit a written request to the OAH online or by mail

You must file within 90 days of the adverse action notice. If your benefits are being reduced or terminated, file within 10 days and request continuation of benefits while the hearing is pending.

At the hearing, you present evidence, your MCO responds, and the ALJ issues a written decision. You can bring a representative or attorney. If you disagree with the decision, you can appeal to Superior Court.

Step 3 — Contact HCA Consumer Support

HCA's Apple Health Customer Service (1-800-562-3022) can help you navigate the system, clarify eligibility, and escalate unresolved complaints. HCA also has a Managed Care Ombudsman that can investigate MCO compliance issues and help you understand your options.

Special Situations in Washington

ALTSA home and community-based services: If your in-home care hours, COPES waiver services, or other LTSS were reduced, file a hearing request immediately. Washington's home care services use a functional assessment (CARE tool) to determine hours. If the assessment was done incorrectly, that's a strong basis for appeal.

Community First Choice (CFC): Washington's CFC program provides attendant care as an entitlement. Denials or reductions of CFC services are subject to strong federal protections.

Apple Health for Kids: Children enrolled in Apple Health — both through Medicaid and the CHIP-funded tier — have full EPSDT protections. If a service was denied for your child, EPSDT may require coverage regardless of standard benefit limits.

Undocumented children: Washington provides full Apple Health coverage to children regardless of immigration status. If a child was denied enrollment, contact HCA immediately.

Refugee Assistance: Washington provides Medicaid-equivalent coverage to qualified refugees. Denials of refugee medical assistance benefits can also be appealed through the OAH hearing process.

Fight Back With ClaimBack

Apple Health appeals require clear medical evidence, proper documentation, and knowledge of Washington's administrative hearing procedures. ClaimBack helps you build a strong appeal quickly.
