Medical records must be maintained and available upon request, be legible, include complete patient identification and dates of service, and contain the legible signature of the physician or non‑physician practitioner responsible for care.
The submitted medical record must support the selected ICD‑10‑CM diagnosis code(s) and the CPT/HCPCS code billed must accurately describe the service performed.
When FDG PET is performed in the context of a CMS‑approved practical clinical trial using a specific protocol, the claim should be reported with modifier Q0.
When only the technical or professional component is performed, report the PET procedure with modifier TC (technical) or 26 (professional), respectively.

FDG PET (CPT 78608 / HCPCS A9552) is covered to differentiate Alzheimer's disease (AD) from frontotemporal dementia (FTD) in patients with a recent dementia diagnosis who have documented cognitive decline for at least 6 months and who meet diagnostic criteria for both AD and FTD.
FDG PET is covered for patients with mild cognitive impairment (MCI) or early dementia only when performed as part of a CMS‑approved practical clinical trial (coverage with evidence development).
FDG PET (CPT 78608) is covered for intractable seizures only when used as part of a pre‑surgical evaluation for seizure focus localization.
Stereotactic radiosurgery (SRS) is typically furnished as a single session; when more than one session is required, bill using stereotactic body radiation therapy (SBRT) codes instead of SRS codes.
Coverage on an individual (redetermination/appeal) basis may be considered for lesions that require a high radiation dose per fraction to avoid exposure of surrounding tissues when documentation and supporting literature are provided.
Urine, blood, or oral fluid specimens may be used for drug testing, with urine preferred for broad screening of common drugs.
