HCPCS procedure codes L7510 (Repair of prosthetic device, repair or replace minor parts) and L8691 (Auditory osseointegrated device, external sound processor, replacement) are allowable for repairs and replacements of bone-anchored hearing devices.
PA is required for procedure code L7510 if the total repair of the bone-anchored hearing device exceeds $150.00 or if the replacement parts of the bone-anchored hearing device have not exceeded their life expectancy.
PA is not required for procedure code L8691.
Note: ForwardHealth assigns "U" modifiers to multiple items listed on PA requests to indicate separate approval of DME items (i.e., accessories).
