Summary
Analysis of the optic nerve and retinal nerve fiber layer in individuals with glaucoma or glaucoma suspects may be considered medically necessary when using scanning laser ophthalmoscopy, scanning laser polarimetry, and optical coherence tomography. Measurement of ocular blood flow, pulsatile ocular blood flow, or blood flow velocity is considered investigational in the diagnosis and follow-up of individuals with glaucoma. The most recent update dated 08/25/2026 updated the policy description regarding devices and removed ICD-9 procedure and diagnosis codes, with policy statements unchanged.
