Official descriptor: CPT 88120 on AAPC
CareSource Georgia Medicaid is implementing new prior authorization requirements effective April 1, 2026, for 57 specific billing codes across multiple service categories including genetic testing, durable medical equipment, orthotic/prosthetic devices, and surgical procedures. All non-participating providers and inpatient services already require prior auth; this update expands requirements to include these specific codes for all providers.
Excellus BlueCross BlueShield policy 2.02.12 considers urinary tumor markers investigational in the diagnosis, monitoring, or screening for bladder cancers. The current version is effective July 16, 2026, and its most recent change is an annual review with the policy intent unchanged. The codes listed in the policy, including CPT 86294, 86386, 88120 and 88121 and the Category III codes listed under CPT, are marked (E/I) Experimental/Investigational.
The policy considers urinary tumor markers investigational for screening, diagnosis, and monitoring of bladder cancer, and for screening for precancerous colonic polyps. The FDA approved or cleared urinary tumor marker tests named in the policy are indicated as adjuncts to standard procedures for initial diagnosis of bladder cancer, surveillance of bladder cancer patients, or identification of colonic polyps, and laboratory-developed tests are offered without FDA regulatory review. A 05/29/2026 update changed the description of laboratory-developed tests and left the policy statement unchanged.
