The procedure described by CPT® Code 27337 involves the excision of a tumor located in the soft tissue of the thigh or knee area, specifically when the tumor measures 3 cm or greater. Soft tissues encompass a variety of structures, including subcutaneous fat, connective tissue, fascia, muscles, tendons, blood vessels, lymph vessels, nerves, and the tissues surrounding joints. Tumors found within these soft tissues can be either benign or malignant. Typically, benign tumors are treated through excision, while small malignant or indeterminate tumors may also be excised if they have well-defined margins. The approach to excision may vary based on the tumor's location; for instance, the skin over the tumor may be incised directly, or a skin flap may be created and elevated to access the tumor. During the procedure, the overlying tissue is carefully dissected to expose the soft tissue mass, which is then excised along with a margin of healthy tissue to ensure complete removal. In some cases, a separately reportable frozen section may be performed to verify that all margins are free of tumor cells, which is crucial for ensuring that the tumor has been completely removed. After the excision, drains may be placed as necessary, and the surgical wound is typically closed in layers to promote proper healing. It is important to note that for tumors located in the subcutaneous fat or connective tissue, CPT® Code 27337 is applicable, while tumors situated below the fascia, such as those within muscle tissue, would require the use of CPT® Code 27339 for excision of soft tissue measuring 5 cm or greater.

The excision of soft tissue tumors in the thigh or knee area, as described by CPT® Code 27337, is indicated for the following conditions:
The procedure for excising a soft tissue tumor in the thigh or knee area involves several key steps:
Post-procedure care following the excision of a soft tissue tumor includes monitoring the surgical site for signs of infection, managing pain, and ensuring proper wound healing. Patients may be advised to keep the area clean and dry, and to follow specific instructions regarding activity restrictions to avoid strain on the surgical site. Follow-up appointments are typically scheduled to assess healing and to remove any sutures if non-absorbable materials were used. Additionally, patients should be informed about signs of complications, such as increased redness, swelling, or discharge from the incision site, which would warrant immediate medical attention.

| RT | Right side (used to identify procedures performed on the right side of the body) | LT | Left side (used to identify procedures performed on the left side of the body) | 22 | Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service. | 47 | Anesthesia by surgeon: regional or general anesthesia provided by the surgeon may be reported by adding modifier 47 to the basic service. (this does not include local anesthesia.) note: modifier 47 would not be used as a modifier for the anesthesia procedures. | 50 | Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d). | 51 | Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d). | 54 | Surgical care only: when 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number. | 58 | Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78. | 59 | Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25. | 76 | Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service. | 78 | Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.) | 79 | Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.) | 80 | Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s). | 82 | Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s). | AF | Specialty physician | AG | Primary physician | AQ | Physician providing a service in an unlisted health professional shortage area (hpsa) | AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | CR | Catastrophe/disaster related | GA | Waiver of liability statement issued as required by payer policy, individual case | GC | This service has been performed in part by a resident under the direction of a teaching physician | GW | Service not related to the hospice patient's terminal condition | GZ | Item or service expected to be denied as not reasonable and necessary | KX | Requirements specified in the medical policy have been met | PD | Diagnostic or related non diagnostic item or service provided in a wholly owned or operated entity to a patient who is admitted as an inpatient within 3 days | SG | Ambulatory surgical center (asc) facility service | XS | Separate structure, a service that is distinct because it was performed on a separate organ/structure | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service |
