Billing and Coding: Visual Fields

This billing and coding policy (A57483) defers clinical coverage and medical necessity criteria to LCD L34615; taped and un-taped visual field tests count as one unit for MUE purposes and separate charges for gross visual fields are denied as incidental. Billing must use modifier -26 for the professional component in hospital inpatient/outpatient settings, adhere to CCI edits for coding, and follow the specified places of service for global, technical, and professional components; unusually frequent testing will be reviewed for medical necessity.

"Taped and un-taped visual field testing count as one unit of service for MUE (medically unlikely edits) purposes."
