Official Description

Excision, tumor, soft tissue of foot or toe, subcutaneous; 1.5 cm or greater

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 28039 involves the excision of a tumor located in the soft tissue of the foot or toe, specifically when the tumor measures 1.5 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 surgical approach 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 frozen section may be performed to verify that all margins are free of tumor cells, which is a separate reportable procedure. After the tumor excision, drains may be placed as necessary, and the surgical wound is typically closed in layers to promote proper healing. For smaller tumors measuring less than 1.5 cm, different CPT codes are utilized, such as CPT® Code 28043 for excision of subcutaneous tumors and CPT® Code 28045 for tumors located below the fascia.

1. Indications

The excision of soft tissue tumors in the foot or toe, as described by CPT® Code 28039, is indicated for the following conditions:

  • Benign Tumors These tumors are typically non-cancerous and may require excision to alleviate symptoms or prevent complications.
  • Malignant Tumors Small malignant or indeterminate tumors may be excised if they have well-defined margins, to ensure complete removal and prevent further spread.
  • Symptomatic Tumors Tumors that cause pain, discomfort, or functional impairment may necessitate surgical intervention.

2. Procedure

The procedure for excising a soft tissue tumor of the foot or toe involves several key steps:

  • Step 1: Preparation The patient is positioned appropriately, and the surgical site is prepared and draped in a sterile manner to minimize the risk of infection.
  • Step 2: Incision Depending on the tumor's location, an incision is made directly over the tumor or a skin flap is created and elevated to provide access to the underlying tissue.
  • Step 3: Dissection The overlying tissue is carefully dissected to expose the soft tissue mass. This step requires precision to avoid damaging surrounding structures.
  • Step 4: Tumor Excision The tumor is excised along with a margin of healthy tissue to ensure complete removal. This is crucial for preventing recurrence and ensuring that all tumor cells are removed.
  • Step 5: Frozen Section (if applicable) A frozen section may be performed during the procedure to assess the margins of the excised tissue, ensuring that they are free of tumor cells.
  • Step 6: Closure After the tumor has been removed, the surgical wound is closed in layers. Drains may be placed as needed to prevent fluid accumulation.

3. Post-Procedure

Post-procedure care following the excision of a soft tissue tumor includes monitoring for any signs of infection, managing pain, and ensuring proper wound healing. Patients may be advised to keep the surgical site clean and dry, and to follow specific instructions regarding activity restrictions to promote recovery. Follow-up appointments may be scheduled to assess healing and to discuss any further treatment if necessary.

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.
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.
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).
55 Postoperative management only: when 1 physician or other qualified health care professional performed the postoperative management and another performed the surgical procedure, the postoperative component may be identified by adding modifier 55 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.
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).
