What 15777 covers

This add-on covers placement of a biologic implant, such as acellular dermal matrix, to reinforce soft tissue. A plastic surgeon commonly uses it during breast reconstruction to support an implant or tissue expander, including reconstruction after mastectomy. The service may also involve reinforcement at another soft-tissue site, such as the trunk, when the implant is used for that purpose.

Report 15777 only with the primary procedure it supplements, not as a standalone service. The operative report should identify the biologic material, the reinforced site, and its role in the reconstruction. CMS pays the add-on within the primary procedure’s global period. For a bilateral procedure reported with modifier 50, CMS pays 150%.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

15777 billing questions

Can 15777 be reported by itself?

No. It is an add-on for biologic implant placement and must be reported with the primary procedure it supplements.

When might 15777 accompany breast reconstruction?

It may accompany reconstruction with a tissue expander or breast implant when biologic material is placed to reinforce soft tissue. The operative documentation should establish that role.

How is bilateral placement reported?

For a bilateral procedure, report modifier 50. CMS pays the bilateral service at 150%.

What should the operative report document?

Document the biologic implant used, the site where it was placed, and how it reinforces soft tissue as part of the primary procedure.

Is 15777 paid outside the primary procedure's global period?

No. CMS identifies it as an add-on paid within the primary procedure’s global period.

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.
