Medical records must document the diagnosis and clinical indication (e.g., increased intraocular pressure, Fuchs dystrophy, ocular trauma, surgical history) and that the pachymetry is integral to medical management.
Provider/supplier must notify the beneficiary in writing prior to rendering the service if the provider is aware the test may not be covered by Medicare.
Services must be performed by or ordered/certified by ophthalmologists or optometrists or by authorized non-physician practitioners as allowed by state law, and that authority should be documented.
For Part A MAC claims and FQHC services, use appropriate bill type codes (e.g., bill type 77X for FQHC services for dates of service on/after April 1, 2010) and document billing per MAC guidance.

Corneal pachymetry is covered for assessment of corneal thickness after ocular trauma.
Corneal pachymetry is covered to assess corneal thickness in suspected glaucoma following a documented diagnosis of increased intraocular pressure prior to initiation of a glaucoma treatment regimen.
