What 15835 covers

CPT 15835 describes an operation to remove excessive skin from the buttock. Plastic surgeons commonly perform this work for redundant tissue that affects the buttock’s contour, including after substantial weight loss. The operative report should identify the buttock as the treated site and describe the skin excised and the procedure performed. This code is site-specific; excess skin removed from a separately treated hip or thigh is represented by a different code in the same family.

Report the code for the buttock work performed, supported by the operative documentation. It has a 90-day global period: the day-before preoperative visit and 90 days of related postoperative care are included. When procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate for this code. An assistant at surgery is paid only when medical necessity is documented; co-surgeons and team surgery are not permitted.

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.

15835 billing questions

How do I distinguish this code from the hip or thigh skin-excision codes?

Use 15835 when the excision is on the buttock. The hip and thigh have separate site-specific codes, 15834 and 15832.

Can modifier 50 be used for both buttocks?

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

What postoperative care is included?

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

How are other procedures performed in the same session paid?

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

When is an assistant at surgery payable?

Payment for an assistant at surgery requires documentation of medical necessity. Co-surgeons and team surgery are not permitted.

What documentation supports reporting 15835?

The operative report should identify the buttock as the treated site and describe the redundant skin removed and the work performed.

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.
