UnitedHealthcare Denied Prior Authorization Denied: How to Appeal" class="auto-link">Prior Authorization: How to Appeal

Prior authorization denials from UnitedHealthcare stop care before it even begins. When UHC denies a prior authorization (PA) request, your provider cannot proceed with the planned treatment without risking a coverage denial. But a PA denial is not final — it can and should be appealed, and UHC has a structured process for doing so.

How UHC's Prior Authorization System Works

UnitedHealthcare requires prior authorization for a broad range of services, including surgeries, advanced imaging (MRI, CT, PET), certain medications, specialty referrals, durable medical equipment, and behavioral health admissions. Providers typically request PA through:

• myuhcprovider.com (online portal)
• UHC's Prior Authorization phone line: 1-888-397-8129 (commercial plans)
• CoverMyMeds or other electronic PA platforms

UHC evaluates PA requests using its Coverage Determination Guidelines and InterQual clinical criteria. If the submitted clinical information does not meet UHC's threshold, the PA is denied.

Common Reasons UHC Denies Prior Authorization

• Insufficient clinical documentation: The most common reason. UHC's PA reviewers require specific clinical indicators, and if the provider's notes don't include them, the request fails.
• Step therapy requirements not met: For medications in particular, UHC often requires that less expensive, "first-line" drugs be tried and failed before it will authorize a more costly option.
• Service not covered under the plan: The plan may simply not include the requested service.
• Wrong level of care requested: For behavioral health admissions, UHC may approve a lower level of care (e.g., outpatient therapy instead of inpatient).
• Coding or administrative errors: Incorrect CPT or ICD-10 codes in the PA request can trigger automatic denials.

How to Appeal a UHC Prior Authorization Denial

Step 1 — Request a Peer-to-Peer Review Before filing a formal appeal, your physician can request a peer-to-peer review — a direct call with UHC's medical director who made the denial decision. Many PA denials are overturned at this stage. Your provider can call UHC's clinical review team using the number on the denial notice.

Step 2 — File a Formal Appeal Within 180 Days If the peer-to-peer review does not resolve the denial, file a formal written appeal within 180 days of the PA denial:

• Online: myuhc.com
• Mail: UnitedHealthcare Appeals, P.O. Box 30432, Salt Lake City, UT 84130
• Phone: 1-866-892-8993

Step 3 — Include Key Supporting Evidence

• Your physician's letter of medical necessity, specifically addressing UHC's denial criteria
• Medical records documenting failed prior treatments (especially important for step therapy appeals)
• Peer-reviewed clinical guidelines (e.g., from the relevant specialty society)
• Any applicable FDA approvals or compendia listings for off-label drug use
• Reference to UHC's own Clinical Coverage Guideline for the denied service (available at UHCprovider.com)

Step 4 — Expedited Appeal for Urgent Care If the denial involves urgent or time-sensitive care, request an expedited appeal. UHC must respond within 72 hours.

Step 5 — External Independent Review: Complete Guide" class="auto-link">External Review After exhausting UHC's internal appeal process, you may request an external independent review. ERISA plan members can also contact the Department of Labor EBSA at 1-866-444-3272.

Step Therapy Appeals: Special Rules

Many states have enacted step therapy exception laws that require insurers to grant exceptions to step therapy requirements when:

• The required first-line drug is contraindicated for the patient
• The patient has already tried and failed the required drug
• The required step therapy would cause adverse effects

If your PA denial is based on step therapy, cite your state's step therapy exception law in your appeal.
