What 27323 covers
A surgeon removes a sample of superficial soft tissue from the thigh or knee area so the tissue can be examined for a suspected tumor or other abnormality. Orthopedic surgeons and surgical oncologists commonly perform the procedure in an outpatient operating room or procedure setting. The code distinguishes a superficial biopsy from sampling deeper soft tissue and from biopsy of the knee joint lining.
Report this code when the operative record supports sampling superficial tissue, rather than complete excision of the lesion. Document the biopsy site, the tissue sampled, and the operative findings; the pathology service may be reported separately when performed by another provider. This minor procedure has a 10-day global period, which includes related postoperative visits during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are paid at 50%. For bilateral reporting, modifier 50 is paid at 150%. Medicare does not pay an assistant at surgery for this procedure; co-surgeons and team surgery are not permitted.

How to choose
- 27324Thigh biopsy
- This code is for superficial soft tissue; 27324 is for deep soft-tissue biopsy. Use the operative description of tissue depth to distinguish them.
- 27327Soft-tissue excision
- Use this biopsy code when tissue is sampled. Code 27327 describes excision of a superficial thigh or knee-area lesion under its applicable size criterion.
- 27328Soft-tissue tumor excision
- This code reports superficial tissue sampling, while 27328 describes excision of a deep thigh or knee-area tumor under its applicable size criterion.
- 27330Knee biopsy
- This code samples superficial soft tissue around the thigh or knee; 27330 is for biopsy of the knee joint lining.
27323 billing questions
How do I distinguish this code from 27324?
Use 27323 for sampling superficial soft tissue in the thigh or knee area. Use 27324 when the biopsy is of deep soft tissue; the operative documentation should support the depth.
When is an excision code more appropriate?
This code describes sampling tissue, not removing the entire lesion. When the surgeon excises a superficial lesion or a deep tumor, consider the applicable excision code, such as 27327 or 27328, based on the documented procedure and lesion.
Can pathology be billed separately?
The surgeon's biopsy service and a pathologist's examination of the specimen are distinct services when each is performed and otherwise reportable. The operative record should identify the submitted tissue and the pathology report should document the examination.
What supports reporting the superficial level?
Document the thigh or knee-area site, the tissue sampled, and operative details that establish the biopsy was superficial rather than deep. A diagnosis of a mass alone does not establish the depth.
How does the 10-day global period affect follow-up?
Related postoperative visits during the 10 days after the biopsy are included in the global period. If other procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the multiple-procedure reduction.
How is a bilateral biopsy reported?
For a bilateral procedure, report modifier 50; CMS pays the bilateral service at 150%. An assistant at surgery is not paid, and co-surgeons and team surgery are not permitted.
