Investigational Services (BSC9.01)
Blue Shield of California's Investigational Services policy (BSC9.01) has an effective date of 09/01/2026. It defines healthcare services as investigational when all three apply: testing is not complete, the efficacy and safety of the service in human subjects are not yet established, and the service is not in wide usage. The policy addresses services that are not covered because they are considered investigational, and its code table lists CPT codes from 22526 through 1025T, many of them effective 1/1/2026.
