Vyvgart Iv MG denied for missing prior authorization by UnitedHealthcare?

UnitedHealthcare's specific coverage criteria for vyvgart iv mg are defined in its own published medical/coverage policy and the FDA-approved prescribing label. A successful appeal documents that your medical records satisfy each criterion those sources list — confirmed diagnosis, any required prior treatments (with dates and outcomes), and clinical severity. If the exact criteria weren't included with your denial, request them in writing; your appeal then maps each requirement to the matching fact in your chart.

## Why UnitedHealthcare Requires Prior Authorization for Vyvgart (efgartigimod alfa) IV

Vyvgart is a specialty biologic requiring prior authorization (PA) under virtually all UnitedHealthcare commercial, Medicare Advantage, and managed Medicaid plans. PA is UHC's mechanism for verifying that the patient meets clinical criteria before the plan pays. A denial for "prior authorization required" typically means either no PA was submitted before the infusion, the PA was submitted but deemed incomplete, or the PA was submitted but UHC determined the documented criteria were not met.

## Why This Denial Is Appealable

If PA was never submitted, work with your infusion center or specialty pharmacy to submit immediately — retroactive PA is sometimes granted for urgent situations. If the PA was denied on clinical grounds, you have the right to a full internal appeal followed by independent external review.

## Your Federal Appeal Rights

• Internal appeal (ACA §2719 / ERISA §503): Submit a written appeal within the deadline stated on the denial letter (often 180 days). UHC must issue a decision within 30 days for pre-service appeals or 60 days for post-service appeals.
• External review: After exhausting internal appeals, escalate to an IRO under ACA §2719 external review provisions. The general window is approximately four months from final internal denial.
• Expedited appeal: Available when standard timelines would seriously jeopardize your health. Decisions are typically rendered within 72 hours.

## Documentation to Gather

1. Diagnosis and antibody status: Confirm the FDA-approved diagnosis in chart notes and lab results. 2. Functional severity documentation: Physician notes, validated clinical assessments, and any hospitalization or crisis records that demonstrate disease burden. 3. Prior therapy record: A chronological list of all previously tried treatments, including start/stop dates and the reason each was discontinued or deemed insufficient. 4. Prescriber medical-necessity letter: The treating neurologist should detail why Vyvgart is medically necessary for this patient at this time, referencing applicable society guidelines without inventing specific numbers.

## Criteria-Mapping Structure

Obtain UHC's current Coverage Determination Guideline for efgartigimod IV from the UHC provider portal. List every criterion. For each criterion, document the corresponding chart evidence and its source (date, provider, note type). Submit this as a structured attachment to your appeal letter so the reviewer can verify compliance criterion by criterion.

## Practical Tip

Ask UHC for the specific clinical rationale for any PA denial — they are required to provide it. This rationale identifies the exact gap to close, whether it is a missing lab result, an inadequately documented prior therapy, or a severity threshold your physician needs to address explicitly.
