What 27328 covers
This service involves surgically removing a tumor beneath the superficial soft tissues of the thigh or knee, such as a subfascial or intramuscular mass, measuring less than 5 cm. It is commonly performed by an orthopedic surgeon or surgical oncologist in an operating room, including a hospital outpatient department or ambulatory surgery center. A diagnostic biopsy alone is not the same service as removing the tumor.
Choose the code based on the operative report’s documented site, depth, size, and procedure. The record should establish that the tumor is deep, measures under 5 cm, and was removed from the thigh or knee area. 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 other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is barred by statutory restriction; co-surgeons and team surgery are not permitted.

27328 billing questions
How does this differ from 27327?
27328 is for a deep thigh or knee tumor under 5 cm. Code 27327 describes removal of a superficial lesion under 3 cm.
When should 27329 be considered instead?
Both codes concern deep thigh or knee tumors under 5 cm, but distinguish the documented operative procedure as excision versus resection. Follow the operative report rather than inferring the code from the diagnosis alone.
What documentation supports 27328?
Document the thigh or knee location, the tumor’s deep or subfascial position, its measured size under 5 cm, and the removal performed. The operative report should support the depth and extent of the work.
Can modifier 50 be used for bilateral procedures?
CMS lists this as a bilateral procedure; reporting modifier 50 is paid at 150%. The record should support treatment of both sides.
How are other procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures in the same session are subject to the standard multiple-procedure reduction, with payment at 50%.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment is barred by statutory restriction. CMS does not permit co-surgeons or team surgery for this code.
