Appeals Playbook for Pennsylvania

Pennsylvania's new external review program, launched in January 2024, has been a game-changer for patients fighting insurance denials. Here's your roadmap:

  • Decision time: 30 days for standard, 72 hours for urgent

From our advocates: We've seen LEMS patients succeed in external review by submitting additional peer-reviewed literature about Firdapse's efficacy alongside their original clinical documentation. The independent medical reviewers often appreciate seeing the broader evidence base beyond just the FDA label.

For expedited external review: Your physician must certify that the delay could seriously jeopardize your health. This applies if LEMS symptoms are rapidly progressing or significantly impacting your safety.

FAQ: Your Top Questions Answered

How long does UnitedHealthcare prior authorization take for Firdapse in Pennsylvania?
Standard PA decisions are made within 15 days, urgent cases within 72 hours. Track status through the UnitedHealthcare Provider Portal.

What if Firdapse isn't on my UnitedHealthcare formulary?
Firdapse may require prior authorization even if listed. Non-formulary medications can be covered through medical necessity appeals citing the lack of therapeutic alternatives for LEMS.

Can I request an expedited appeal if my LEMS symptoms are worsening?
Yes. Both internal appeals and Pennsylvania external review offer expedited timelines (72 hours) when delay could seriously jeopardize your health.

Does step therapy apply to Firdapse for LEMS patients?
No. UnitedHealthcare's policy specifically states step therapy is not required for Firdapse when prescribed for LEMS diagnosis.

What happens if I'm already taking Firdapse and my renewal is denied?
Continue current therapy while appealing (if financially feasible) and request expedited review. Interrupting LEMS treatment can cause rapid symptom return.

Can my neurologist do a peer-to-peer review with UnitedHealthcare?
Yes. Request peer-to-peer review through the provider portal or by calling the number on the denial letter. This often resolves denials quickly when a specialist can explain the medical necessity directly.

What if I move to Pennsylvania from another state while on Firdapse?
Contact UnitedHealthcare to confirm your new plan's coverage. You may need new prior authorization, but existing treatment history strengthens your case.

How do I find a neuromuscular specialist in Pennsylvania for LEMS diagnosis?
Use UnitedHealthcare's provider directory to find in-network neurologists with neuromuscular subspecialty. Major medical centers like Penn Medicine and UPMC have specialized clinics.
