Prior authorization to UnitedHealthcare

UnitedHealthcare is one of the largest commercial insurers in the US, covering commercial, Medicare Advantage, and Medicaid members nationwide. Most PA requests are reviewed through the UHC Provider Portal. Before submitting, verify whether your procedure routes through a specialty program — imaging, behavioral health, and specialty pharmacy often have separate review pathways that require a different portal or additional documentation.
