Official Description

Excision, benign lesion including margins, except skin tag (unless listed elsewhere), trunk, arms or legs; excised diameter 2.1 to 3.0 cm

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 11403 involves the excision of a benign lesion from the trunk, arms, or legs, specifically when the excised diameter of the lesion measures between 2.1 to 3.0 cm. A benign lesion is defined as a non-cancerous growth that does not pose a threat to health, and it excludes skin tags unless specified otherwise. Common examples of benign lesions that may be excised include lipomas, which are fatty tumors; dermatofibromas, which are fibrous skin growths; pyogenic granulomas, which are small, red, and raised lesions; epidermoid cysts, which are small lumps beneath the skin; and benign nevi, commonly known as moles. During the procedure, the area surrounding the lesion is first cleansed to reduce the risk of infection, followed by the administration of a local anesthetic to ensure patient comfort. The surgeon then identifies a narrow margin of healthy tissue surrounding the lesion to ensure complete removal. A full-thickness incision is made through the dermis, and the incision is carefully carried around the lesion to excise it entirely. After excision, the lesion is sent to a laboratory for histologic evaluation, which is separately reportable. To manage any bleeding that may occur during the procedure, electrocautery or chemical cautery techniques are employed. Finally, the surgical wound may be closed using a simple single-layer suture technique, although more complex methods such as intermediate (layer) closure, complex repair, skin grafts, or pedicle flaps may also be utilized depending on the specific circumstances of the excision and the wound's characteristics.

1. Indications

The procedure associated with CPT® Code 11403 is indicated for the excision of benign lesions located on the trunk, arms, or legs. These lesions are typically non-cancerous and may include a variety of conditions that warrant removal for reasons such as cosmetic concerns, discomfort, or potential complications. The specific indications for this procedure include:

  • Benign Lipomas - Soft, fatty tumors that can be found under the skin.
  • Dermatofibromas - Firm, raised nodules that are often brownish in color and can be mistaken for other skin conditions.
  • Pyogenic Granulomas - Small, red, and raised lesions that can bleed easily and may develop following injury or irritation.
  • Epidermoid Cysts - Small, round lumps beneath the skin that can become inflamed or infected.
  • Benign Nevi - Commonly known as moles, these are usually harmless but may be excised for cosmetic reasons or if there are changes in appearance.

2. Procedure

The procedure for excising a benign lesion as described by CPT® Code 11403 involves several critical steps to ensure the complete and safe removal of the lesion. The steps are as follows:

  • Step 1: Preparation - The area surrounding the lesion is thoroughly cleansed to minimize the risk of infection. This is a crucial step in preparing the surgical site.
  • Step 2: Anesthesia - A local anesthetic is injected into the area to ensure that the patient remains comfortable and pain-free during the procedure.
  • Step 3: Incision - The surgeon identifies a narrow margin of healthy tissue around the lesion. A full-thickness incision is then made through the dermis, ensuring that the incision encompasses the entire lesion.
  • Step 4: Excision - The incision is carefully carried around the lesion, allowing for the complete excision of the benign growth along with the surrounding healthy tissue.
  • Step 5: Histologic Evaluation - Once excised, the lesion is sent to a laboratory for histologic evaluation, which is a separate reportable procedure that helps confirm the benign nature of the lesion.
  • Step 6: Hemostasis - Any bleeding that occurs during the procedure is controlled using electrocautery or chemical cautery techniques to ensure a clean surgical field.
  • Step 7: Wound Closure - The surgical wound may be closed using a simple single-layer suture technique. Depending on the complexity of the excision and the characteristics of the wound, other closure methods such as intermediate (layer) closure, complex repair, skin grafts, or pedicle flaps may also be employed.

3. Post-Procedure

After the excision procedure is completed, the patient may be monitored for any immediate complications. Post-procedure care typically includes instructions for wound care to promote healing and prevent infection. Patients are advised to keep the area clean and dry, and to follow any specific guidelines provided by the healthcare provider regarding suture care and activity restrictions. Follow-up appointments may be scheduled to assess the healing process and to discuss the results of the histologic evaluation. It is important for patients to report any signs of infection, such as increased redness, swelling, or discharge from the surgical site, to their healthcare provider promptly.

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).
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.
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.)
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
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.
GZ Item or service expected to be denied as not reasonable and necessary
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
RT Right side (used to identify procedures performed on the right side of the body)
AQ Physician providing a service in an unlisted health professional shortage area (hpsa)
KX Requirements specified in the medical policy have been met
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.)
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
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.
25 Significant, separately identifiable evaluation and management service by the same physician or other qualified health care professional on the same day of the procedure or other service: it may be necessary to indicate that on the day a procedure or service identified by a cpt code was performed, the patient's condition required a significant, separately identifiable e/m service above and beyond the other service provided or beyond the usual preoperative and postoperative care associated with the procedure that was performed. a significant, separately identifiable e/m service is defined or substantiated by documentation that satisfies the relevant criteria for the respective e/m service to be reported (see evaluation and management services guidelines for instructions on determining level of e/m service). the e/m service may be prompted by the symptom or condition for which the procedure and/or service was provided. as such, different diagnoses are not required for reporting of the e/m services on the same date. this circumstance may be reported by adding modifier 25 to the appropriate level of e/m service. note: this modifier is not used to report an e/m service that resulted in a decision to perform surgery. see modifier 57 for significant, separately identifiable non-e/m services, see modifier 59.
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).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) 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).
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.
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).
