What 27337 covers
This service covers definitive surgical removal of a soft-tissue mass located beneath the skin in the thigh or knee area, measuring at least 3 cm. An orthopedic or general surgeon may perform it in an operating room or another appropriate procedural setting. A palpable subcutaneous mass, such as a lipoma, may be removed when treatment or diagnosis calls for excision rather than a limited tissue sample. The code is for a superficial lesion, not a mass situated in deeper soft tissue.
Choose this code when the operative documentation supports the thigh or knee location, subcutaneous depth, and size threshold. Record the lesion’s measured size and the tissue plane involved; the operative report should show that the service was removal, not sampling alone. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. For bilateral procedures reported with modifier 50, payment is 150%. Assistant-at-surgery payment may be made; co-surgeons and team surgery are not permitted.

27337 billing questions
When should this code be selected instead of 27327?
Use 27337 for a subcutaneous thigh or knee lesion measuring 3 cm or larger. Code 27327 describes the same general site and tissue depth for a lesion smaller than 3 cm.
How does a deep mass change code selection?
This code is for a lesion beneath the skin in the subcutaneous plane. A mass documented in deeper soft tissue may fall under a deep-tumor code, with the applicable size threshold determining the choice.
Can a biopsy of the same lesion be reported with its excision?
When tissue sampling is part of the process leading to definitive removal of that same lesion, the operative service is the excision. A biopsy code is for sampling rather than complete removal.
What documentation supports reporting 27337?
Document the thigh or knee location, that the lesion is subcutaneous, its size of at least 3 cm, and the operative work showing removal. The note should distinguish the lesion from a deeper mass or a sample-only procedure.
What payment rules affect this service?
It has a 90-day global period, and standard multiple-procedure reduction applies when other procedures are performed in the same session. Bilateral reporting with modifier 50 is paid at 150%; assistant-at-surgery payment may be made, while co-surgeons and team surgery are not permitted.

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.
