Answer Box: Renewing Isturisa Coverage with UnitedHealthcare in Pennsylvania

UnitedHealthcare typically requires annual prior authorization renewal for Isturisa (osilodrostat), with submission needed 30-60 days before expiration. Key requirements include recent 24-hour urine free cortisol (UFC) levels showing response, endocrinologist notes confirming ongoing need, and safety monitoring documentation. If renewal is denied, Pennsylvania's Independent External Review program has overturned ~53% of denials in 2024.

First step today: Check your current PA expiration date via myuhc.com or call the number on your insurance card, then schedule follow-up labs with your endocrinologist 6-8 weeks before renewal is due.

Renewal Triggers: Timing Windows

UnitedHealthcare/OptumRx generally requires annual prior authorization renewal for specialty medications like Isturisa, with no public indication that osilodrostat has been exempted from reauthorization requirements as of 2025.

Signs You Should Start Early

  • 90 days before expiration: Schedule follow-up appointment with your endocrinologist
  • 60 days before: Order required lab work (UFC, cortisol levels, safety monitoring)
  • 30 days before: Submit renewal documentation
  • 15 days before: Follow up if no decision received
Note: OptumRx has been reducing reauthorization requirements for some chronic medications, but Cushing's disease treatments are not among the 140+ medications with eliminated reauthorizations.

How to Find Your Current Expiration Date

  1. Log into myuhc.com → Pharmacy → Prior Authorization Status
  2. Call the member services number on your insurance card
  3. Check with your pharmacy—they'll receive rejection notices when PA expires

FAQ

How long does UnitedHealthcare PA renewal take in Pennsylvania? Standard renewals typically take 15-30 business days from complete submission. Expedited reviews for urgent medical situations are decided within 72 hours.

What if Isturisa moves to a higher formulary tier? You can request a formulary exception if the tier change significantly increases your costs. Your endocrinologist will need to document why Isturisa is medically necessary over lower-tier alternatives.

Can I request an expedited renewal if my PA is about to expire? Yes, if interruption of Isturisa would pose serious health risks. Your doctor must complete a physician certification form documenting the urgent medical need.

Does step therapy apply if I've already been on Isturisa successfully? Generally no—once you've demonstrated clinical response to Isturisa, UnitedHealthcare shouldn't require you to try other medications first during renewal. If they do, this is grounds for an appeal.

What happens if I miss the renewal deadline? Your pharmacy will receive a rejection when trying to fill your prescription. Contact UnitedHealthcare immediately to request a late renewal submission, and ask your doctor about bridge therapy options while the renewal is processed.

How do I know if my plan is self-funded vs. fully-insured? Check your benefits booklet or ask your employer's HR department. Self-funded plans use federal external review, while fully-insured Pennsylvania plans can use the state's external review program with its higher success rate.
