Documentation Required

- Documentation should include relevant medical history, a physical examination, and results of pertinent diagnostic tests or procedures supporting the need for visual fields testing.
- The diagnosis code(s) reported on the claim must best describe the patient's condition for which the visual fields testing was performed.
- Refer to NCCI and OPPS requirements prior to billing Medicare to ensure coding compliance and to determine any bundling or packaging edits.
Key Coverage Criteria
- 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.
- Medicare Part B will pay for drug screening services when all coverage criteria, limitations, and medical necessity requirements of LCD DL34645 are met.
- Claims for drug screening services are payable under Medicare Part B only in these places of service: office (11), urgent care (20), independent clinic (49), federally qualified health center — freestanding (50), rural health clinic — freestanding (72), and independent laboratory (81).
- Ambulatory EEG is covered for diagnostic evaluation when seeking to detect clinical seizures or interictal epileptiform activity.
