Medical Policy and Coding Updates - November 2026
Premera Blue Cross (WA) published its November 2026 medical policy and coding update. Several changes take effect on different dates: Nov 1, Nov 6, Nov 15, Nov 16, 2026, Dec 3, 2026, Jan 1, 2027, and Feb 5, 2027, including new prior authorization/medical necessity review requirements for specific CPT/HCPCS codes (e.g., 33340, 31240, J1818, J9999, 52284, 17313–17315, 30117, 31242, 31243, S3600, S3601, C9762, C9763) and some codes now considered investigational or non-covered. Because the notice mixes past, current and future effective dates, the billing team should confirm applicability per date and per plan before acting.
