Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 65135 covers

An ophthalmic or oculoplastic surgeon places an orbital implant in the socket and attaches the extraocular muscles to the implant. This may be part of reconstruction after loss or removal of an eye. The implant is internal; an external prosthetic eye is a separate device. Code selection turns on whether the muscles are attached to the implant, rather than simply placed over or around it. If the eye is removed during the same operation and the applicable enucleation code includes implant placement, that combined service is represented by the enucleation code rather than a separate insertion code.

The operative report should identify the implant placement and describe the muscle attachment. CMS assigns a 90-day global period: the day-before preoperative visit and 90 days of related postoperative care are included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. For bilateral reporting with modifier 50, CMS pays 150%. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.
