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.

Visual field testing is covered when billed to the Part A or Part B MAC with a valid ICD-10-CM diagnosis code that best describes the patient’s condition and when the service is reasonable and necessary.
For diagnostic visual field tests, report the test result on the claim if known; if the result is not known, report the signs or symptoms that prompted the test.
If the service requires a referring/ordering physician, include the ordering/referring physician’s name and NPI on the claim.
