What 65780 covers
An ophthalmologist, often a cornea specialist, places multiple layers of amniotic membrane on the ocular surface to support reconstruction and healing. This approach may be used for severe surface damage, including a persistent epithelial defect or injury from a chemical or thermal burn. The service is typically performed in an operating room or other surgical setting when the extent of the ocular surface problem calls for multilayer reconstruction.
Report this code when the operative record supports amniotic membrane reconstruction using multiple layers. The documentation should identify the treated eye, the ocular surface condition, and the multilayer technique; do not report separate units for each layer. Medicare assigns a 90-day global period, which includes the day-before preoperative visit and related postoperative care during that period. 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% reduction. Modifier 50 applies to bilateral procedures, paid at 150%. Assistant-at-surgery payment is restricted; co-surgeons require supporting documentation, and team surgery is not permitted.

How to choose
- 65778Amniotic membrane
- Use 65778 for single-layer amniotic membrane treatment with a self-retaining technique; use 65780 when multiple layers are placed.
- 65779Amniotic membrane
- Use 65779 for a single sutured layer. The multilayer reconstruction described by 65780 is a different service.
- 65781Ocular reconstruction
- 65781 involves limbal stem cell allograft reconstruction, rather than multilayer amniotic membrane placement.
- 65782Ocular reconstruction
- 65782 uses the patient's own limbal stem cells for reconstruction; 65780 represents multilayer amniotic membrane reconstruction.
65780 billing questions
How do I distinguish this from 65778 or 65779?
This code is for multilayer amniotic membrane reconstruction. Codes 65778 and 65779 describe single-layer techniques, distinguished by whether the membrane is self-retaining or sutured.
Can I report multiple units for multiple membrane layers?
No. The multiple-layer technique is represented by this code; do not count each layer as a separate unit.
What documentation supports the code?
Document the ocular surface condition, the treated eye, and that the reconstruction used multiple layers of amniotic membrane.
How does the 90-day global period affect postoperative billing?
The day-before preoperative visit and related postoperative care for 90 days are included in the global period.
Can this be billed bilaterally?
For bilateral performance, CMS pays the procedure with modifier 50 at 150%.
Can an assistant surgeon or co-surgeon be reported?
Assistant-at-surgery payment is subject to a statutory restriction. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
