Official Description

Excision, tumor, soft tissue of abdominal wall, subfascial (eg, intramuscular); 5 cm or greater

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 22901 refers to the excision of a tumor located in the soft tissue of the abdominal wall, specifically when the tumor is subfascial, meaning it is situated beneath the fascia, which is a layer of connective tissue. This procedure is applicable for tumors that measure 5 centimeters 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 in 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 involve incising the skin directly over the tumor or creating and elevating a skin flap to provide better access to 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 the 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. For smaller tumors in the subcutaneous fat or connective tissue, different codes are used, such as CPT® Code 22902 for masses less than 3 cm and CPT® Code 22903 for masses 3 cm or greater. For tumors located below the fascia, CPT® Code 22900 is designated for masses less than 5 cm, while CPT® Code 22901 is specifically for those measuring 5 cm or greater, highlighting the importance of accurate coding based on the size and location of the tumor.

1. Indications

The excision of a tumor in the soft tissue of the abdominal wall, as described by CPT® Code 22901, is indicated for the following conditions:

  • Soft Tissue Tumors Tumors located in the soft tissues of the abdominal wall that may be benign or malignant.
  • Size of Tumor Tumors that measure 5 cm or greater, necessitating excision to ensure complete removal and to assess margins.
  • Well-Defined Margins Small malignant or indeterminate tumors with well-defined margins that may require excision.

2. Procedure

The procedure for excising a subfascial tumor of the abdominal wall involves several critical steps:

  • Incision The surgeon begins by making an incision in the skin over the tumor or creating a skin flap to gain access to the underlying tissue. This approach is determined based on the tumor's location and size.
  • Tissue Dissection Once access is achieved, the overlying tissue is carefully dissected to expose the soft tissue mass. This step is crucial to ensure that the tumor is adequately visualized and that surrounding structures are preserved.
  • Excision of Tumor The tumor is excised along with a margin of healthy tissue to ensure complete removal. This margin is essential for reducing the risk of recurrence and ensuring that all tumor cells are removed.
  • Frozen Section Analysis If necessary, a frozen section may be performed during the procedure to confirm that the margins are free of tumor cells. This step provides immediate feedback to the surgeon regarding the adequacy of the excision.
  • Placement of Drains After the tumor has been excised, drains may be placed as needed to prevent fluid accumulation in the surgical site, which can aid in the healing process.
  • Closure of Wound Finally, the surgical wound is closed in layers, ensuring that the skin and underlying tissues are properly aligned to promote optimal healing.

3. Post-Procedure

Post-procedure care following the excision of a subfascial tumor includes monitoring for any signs of complications, such as infection or excessive bleeding. Patients may be advised to keep the surgical site clean and dry, and to follow specific instructions regarding activity restrictions to promote healing. Follow-up appointments are typically scheduled to assess the surgical site and to discuss the results of any pathology reports, particularly if a frozen section was performed. The recovery period may vary depending on the individual patient and the extent of the surgery, but patients are generally encouraged to report any unusual symptoms or concerns to their healthcare provider promptly.

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.
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).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
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.
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).
