The introduction to the NCD manual states “Where coverage of an item or service is provided for specified indications or circumstances but is not explicitly excluded for others, or where the item or service is not mentioned at all in the CMS Manual System the Medicare contractor is to make the coverage decision, in consultation with its medical staff, and with CMS when appropriate, based on the law, reg-ulations, rulings and general program instructions”. This includes confrontational visual field testing, static perimetry and kinetic perimetry. It is a covered service when used in assessing visual fields in patients with glaucoma or other neuro-pathologic defects.” Most Medicare Administrative Contractors (MACs) also publish local coverage determination (LCD) policies that supplement the NCD; check your local policies.
