Frequently Asked Questions

Q: How long does UnitedHealthcare PA take for Opfolda in Michigan? A: Standard review takes 7-14 business days for complete submissions. Expedited review (24-72 hours) is available for urgent medical situations.

Q: What if Opfolda is non-formulary on my plan? A: Opfolda is covered when PA criteria are met, regardless of formulary tier. Non-formulary status doesn't prevent coverage with proper authorization.

Q: Can I request expedited appeal if my condition is worsening? A: Yes. Michigan offers expedited external appeals within 72 hours when a physician certifies that delay would harm the patient's health.

Q: Does step therapy apply if I've tried ERTs outside Michigan? A: Yes, ERT failure documentation from any location is acceptable. UnitedHealthcare's step therapy requirements are based on clinical history, not geographic location.

Q: What happens if I move from Michigan to another state? A: Your UnitedHealthcare coverage continues, but external appeal rights follow your new state's regulations. Contact your new state insurance department for appeal procedures.

Q: Can my doctor represent me in appeals? A: Yes. Michigan allows physicians to file appeals on behalf of patients with proper authorization. This often strengthens the clinical argument.

From our advocates: We've seen the strongest Opfolda approvals include both objective clinical measures (like specific FVC decline percentages) and detailed specialist notes explaining why standard ERTs aren't meeting the patient's needs. The key is painting a complete clinical picture that directly addresses UnitedHealthcare's coverage criteria.

When navigating insurance coverage for rare disease treatments like Opfolda, having expert support can make the difference between approval and denial. Counterforce Health specializes in turning insurance denials into targeted, evidence-backed appeals by analyzing denial letters, plan policies, and clinical notes to create compelling cases that address payer-specific requirements. The platform helps patients, clinicians, and specialty pharmacies get prescription drugs approved by identifying the exact denial basis and drafting point-by-point rebuttals aligned to each plan's own rules.
