What 15570 covers

This service covers creating a skin flap that remains attached to its blood supply through a pedicle, with or without moving it to the recipient site. It is used for trunk reconstruction, such as coverage of a defect on the chest, back, or abdomen. Plastic and reconstructive surgeons commonly perform the procedure in a hospital or outpatient surgical setting when local tissue can be used to cover the defect while maintaining vascular attachment.

Select the code by the flap method and the trunk location, rather than by defect size alone; document the donor and recipient sites and how the flap is formed and transferred. Medicare assigns a 90-day global period, including 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 is inappropriate for this code. Medicare does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.

15570 billing questions

When should I report 15570 rather than an adjacent tissue transfer code?

Report 15570 when the surgeon forms a direct or tubed skin pedicle flap for a trunk defect. Adjacent tissue transfer codes describe local tissue rearrangement rather than this pedicle-flap method.

How is 15570 different from 15572?

The recipient area determines the site-specific code: 15570 is for the trunk, while 15572 is for an arm or leg.

Can I report modifier 50 for a flap on each side of the trunk?

No. CMS identifies bilateral adjustment as inappropriate for this code; modifier 50 should not be used.

Does the 90-day global period include related postoperative care?

Yes. The global period includes the day-before preoperative visit and 90 days of related postoperative care.

Can an assistant or co-surgeon be paid for this procedure?

Medicare does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.

How does Medicare handle other procedures performed in the same session?

The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction.

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.
