Arikayce Coverage with UnitedHealthcare in California: Complete Guide to Prior Authorization, Appeals, and Approval Timeline

Answer Box: Getting Arikayce Covered by UnitedHealthcare in California

Arikayce requires prior authorization from UnitedHealthcare through OptumRx. To qualify, you must have refractory MAC lung disease with positive cultures after at least 6 months of combination therapy (macrolide + ethambutol + rifamycin). Your fastest path: Have your pulmonologist or infectious disease specialist submit complete documentation through the UnitedHealthcare Provider Portal, including treatment history, culture results, and susceptibility testing. Standard review takes 7-14 days; expedited review 72 hours. If denied, California's Independent Medical Review (IMR) offers a 50-65% success rate for specialty drug appeals.

From Our Advocates

"We've seen patients succeed with Arikayce appeals by focusing on three key elements: comprehensive documentation of treatment failures, recent culture data showing persistent MAC positivity, and clear specialist support. One common mistake is submitting incomplete susceptibility testing—make sure amikacin MIC values are current and clearly documented. While outcomes vary, patients who provide thorough clinical evidence typically see better results in both initial reviews and appeals."
