Standard (non-urgent) prior authorization decisions must be made within 24 to 72 hours for most plans. Medicare Part D requires a decision within 72 hours (24 hours for expedited requests). In practice, delays can occur if your doctor's office is slow to submit paperwork or if additional documentation is requested. Electronic PA is speeding up the process.
If denied, you have the right to appeal. Your doctor can submit additional clinical documentation supporting the medical necessity of the prescribed drug. First-level appeals are reviewed by the insurer. If the internal appeal is denied, you can request an independent external review. You should also ask about covered alternatives while the appeal is pending.
You can often avoid PA by asking your doctor to prescribe a formulary drug that does not require PA. Check your plan's formulary for alternatives in the same drug class. Many common generics have no PA requirement. If you need the specific drug that requires PA, your doctor's office should initiate the process proactively before you go to the pharmacy.
