What 27618 covers

This code describes excision of a soft-tissue tumor smaller than 3 cm that lies beneath the skin but remains subcutaneous in the leg or ankle area. An orthopedic surgeon or another surgeon may perform it in an operating room or an outpatient procedure setting. A small superficial lipoma is a typical example; the operative report should establish the mass’s location, size, and depth.

Choose this code when the surgeon removes the tumor, not when only a tissue sample is taken. Distinguish it from codes for larger subcutaneous tumors and for tumors beneath the fascia. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; 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.

27618 billing questions

How does 27618 differ from 27619?

27618 is for a subcutaneous tumor under 3 cm. 27619 is for a deep soft-tissue tumor under 5 cm.

Is 27618 appropriate when the surgeon takes only a biopsy?

No. This code describes excision of the tumor, rather than sampling only part of it. Consider the applicable soft-tissue biopsy code when the surgeon obtains tissue for diagnosis without removing the entire mass.

What documentation supports 27618?

The operative report should identify the leg or ankle site, document that the tumor is subcutaneous, and record its size as under 3 cm. It should also describe removal of the tumor.

How is bilateral reporting handled?

CMS pays bilateral reporting with modifier 50 at 150%. The record should support a qualifying procedure on both sides.

Can an assistant surgeon or co-surgeon be reported?

CMS restricts assistant-at-surgery payment for this code. Co-surgeons and team surgery are not permitted.
