Summary
Laser treatment of onychomycosis is considered investigational under this policy, and investigational services are not considered medically necessary. Multiple Nd:YAG laser systems have been cleared by the FDA for the temporary increase of clear nail in patients with onychomycosis. Federal Employee Program (FEP) may dictate that FDA-approved devices may not be considered investigational, so these devices may be assessed only on the basis of medical necessity. The policy was reviewed on 05/22/2026 with no changes.
