Official Description

Excision, malignant lesion including margins, trunk, arms, or legs; excised diameter 1.1 to 2.0 cm

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 11602 refers to the excision of a malignant lesion located on the trunk, arms, or legs, specifically when the excised diameter of the lesion measures between 1.1 to 2.0 cm. This procedure involves the surgical removal of the malignant tissue along with a margin of healthy tissue to ensure complete excision of the cancerous cells. Common types of malignant lesions that may be excised using this code include basal cell carcinoma, squamous cell carcinoma, verrucous carcinoma, and melanoma. The process begins with the cleansing of the area and the administration of a local anesthetic to minimize discomfort during the procedure. A careful identification of a healthy tissue margin is crucial, followed by a full-thickness incision made through the dermis surrounding the lesion. The entire lesion is then excised, and if necessary, a frozen section may be performed to verify that the margins are clear of malignant cells. Should any malignant tissue be detected at the margins, additional excision is performed until all margins are confirmed clean. The excised lesion is subsequently sent to a laboratory for histologic evaluation, which is also reportable separately. To manage any bleeding 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 closure 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.

1. Indications

The procedure associated with CPT® Code 11602 is indicated for the excision of malignant lesions on the trunk, arms, or legs. The specific conditions or symptoms that warrant this procedure include:

  • Basal Cell Carcinoma - A common form of skin cancer that typically appears as a small, shiny bump or a sore that does not heal.
  • Squamous Cell Carcinoma - A type of skin cancer that may present as a firm red nodule, a flat sore with a scaly crust, or a new sore that does not heal.
  • Verrucous Carcinoma - A variant of squamous cell carcinoma that is characterized by a wart-like appearance and is often found in the oral cavity or on the skin.
  • Melanoma - A serious form of skin cancer that develops from melanocytes and can appear as a new or changing mole, often with irregular borders and multiple colors.

2. Procedure

The procedure for excising a malignant lesion as described by CPT® Code 11602 involves several critical steps:

  • Step 1: Preparation - The area surrounding the malignant lesion is thoroughly cleansed to reduce the risk of infection. A local anesthetic is then injected to ensure the patient experiences minimal discomfort during the excision.
  • Step 2: Identification of Margins - The surgeon carefully identifies a margin of healthy tissue surrounding the lesion. This margin is essential to ensure that all cancerous cells are removed during the excision.
  • Step 3: Incision - A full-thickness incision is made through the dermis, encircling the lesion. This incision is designed to remove the lesion along with the identified margin of healthy tissue.
  • Step 4: Excision - The entire lesion, along with the surrounding healthy tissue, is excised. This step is crucial for ensuring that no malignant cells remain at the site of the lesion.
  • Step 5: Frozen Section Analysis - If necessary, a frozen section may be performed at the time of excision. This involves taking a small sample of the excised tissue to check for the presence of malignant cells at the margins. If malignant tissue is detected, additional excision is performed until clear margins are achieved.
  • Step 6: Laboratory Evaluation - The excised lesion is sent to a laboratory for histologic evaluation, which is reportable separately. This evaluation helps confirm the diagnosis and assess the completeness of the excision.
  • Step 7: Hemostasis - During the procedure, any bleeding is controlled using electrocautery or chemical cautery techniques to minimize blood loss and promote a clean surgical field.
  • Step 8: Wound Closure - The surgical wound may be closed using a simple single-layer suture technique. However, depending on the complexity of the excision and the size of the wound, other closure methods such as intermediate (layer) closure, complex repair, skin grafts, or pedicle flaps may be employed.

3. Post-Procedure

After the excision procedure associated with CPT® Code 11602, patients can expect specific post-procedure care and considerations. The surgical site will require monitoring for signs of infection, such as increased redness, swelling, or discharge. Patients are typically advised to keep the area clean and dry, and to follow any specific wound care instructions provided by the healthcare provider. Pain management may be necessary, and over-the-counter pain relievers may be recommended. Follow-up appointments are essential to assess the healing process and to discuss the results of the histologic evaluation. If additional treatment is required based on the pathology report, the healthcare provider will discuss the next steps with the patient. Overall, the recovery period may vary depending on the individual and the complexity of the excision, but most patients can expect to resume normal activities within a few days, barring any complications.

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).
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.)
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.
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.
GC This service has been performed in part by a resident under the direction of a teaching physician
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.

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).
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.
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.
74 Discontinued out-patient hospital/ambulatory surgery center (asc) procedure after administration of anesthesia: due to extenuating circumstances or those that threaten the well being of the patient, the physician may terminate a surgical or diagnostic procedure after the administration of anesthesia (local, regional block(s), general) or after the procedure was started (incision made, intubation started, scope inserted, etc). under these circumstances, the procedure started but terminated can be reported by its usual procedure number and the addition of modifier 74. note: the elective cancellation of a service prior to the administration of anesthesia and/or surgical preparation of the patient should not be reported. for physician reporting of a discontinued procedure, see modifier 53.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 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.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
99 Multiple modifiers: under certain circumstances 2 or more modifiers may be necessary to completely delineate a service. in such situations modifier 99 should be added to the basic procedure, and other applicable modifiers may be listed as part of the description of the service.
