What 65779 covers
An ophthalmologist places one amniotic membrane layer over the ocular surface and secures it with sutures. This approach may be used for a persistent corneal epithelial defect or other ocular-surface damage when coverage is needed to support healing. The operative record should establish the ocular surface treated and that the membrane was placed as a single layer and sutured.
Select this code for sutured single-layer placement, not for a self-retaining membrane application or a multi-layer ocular surface reconstruction. The 0-day global period includes same-day preoperative and postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. For bilateral treatment, modifier 50 is paid at 150%. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.
