Official Description

Excision, malignant lesion including margins, scalp, neck, hands, feet, genitalia; excised diameter 0.5 cm or less

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 11620 refers to the excision of a malignant lesion from specific anatomical locations, including the scalp, neck, hands, feet, or genitalia, with an excised diameter of 0.5 cm or less. This procedure involves the surgical removal of a cancerous growth along with a margin of healthy tissue to ensure complete excision of the malignancy. 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 affected area, followed by the administration of a local anesthetic to minimize discomfort during the procedure. A full-thickness incision is then made through the dermis, encircling the lesion to facilitate its complete removal. To confirm that the excised margins are free of malignant cells, a frozen section may be performed during the procedure. If any malignant tissue is detected at the margins, additional tissue will be excised until clear margins are achieved. The excised lesion is subsequently sent to a laboratory for histologic evaluation, which is also reportable separately. Hemostasis is typically achieved using electrocautery or chemical cautery techniques. After the lesion is removed, the surgical wound may be closed using a simple single-layer suture technique; however, more complex closure methods such as intermediate (layer) closure, complex repair, skin grafts, or pedicle flaps may also be employed depending on the specific circumstances of the excision.

1. Indications

The procedure associated with CPT® Code 11620 is indicated for the excision of malignant lesions located on the scalp, neck, hands, feet, or genitalia. These lesions may include:

  • Basal Cell Carcinoma - A common form of skin cancer that arises from the basal cells in the epidermis.
  • Squamous Cell Carcinoma - A type of skin cancer that originates from squamous cells, which are flat cells found in the outer layer of the skin.
  • Verrucous Carcinoma - A variant of squamous cell carcinoma that is characterized by a slow-growing, wart-like appearance.
  • Melanoma - A serious form of skin cancer that develops from melanocytes, the cells that produce pigment in the skin.

2. Procedure

The procedure for excising a malignant lesion as described by CPT® Code 11620 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 procedure.
  • Step 2: Incision - A full-thickness incision is made through the dermis, carefully encircling the lesion. This incision is designed to include a margin of healthy tissue surrounding the malignant growth to ensure complete removal.
  • Step 3: Excision - The surgeon excises the entire lesion along with the surrounding healthy tissue. This step is crucial for ensuring that all cancerous cells are removed from the body.
  • Step 4: Frozen Section Analysis - At this point, a frozen section may be performed to evaluate the margins of the excised tissue. This analysis helps determine if any malignant cells remain at the edges of the excised tissue.
  • Step 5: Additional Excision (if necessary) - If malignant tissue is detected at the margins during the frozen section analysis, additional tissue is excised until clear margins are confirmed.
  • Step 6: Histologic Evaluation - The excised lesion is sent to a laboratory for histologic evaluation, which is reportable separately. This evaluation provides critical information regarding the nature of the lesion and the adequacy of the excision.
  • Step 7: Hemostasis - Bleeding is controlled using electrocautery or chemical cautery techniques to ensure that the surgical site is stable and minimizes the risk of postoperative complications.
  • Step 8: Wound Closure - The surgical wound may be closed using a simple single-layer suture technique. However, depending on the size and complexity of the excision, other closure methods such as intermediate (layer) closure, complex repair, skin grafts, or pedicle flaps may be utilized.

3. Post-Procedure

After the excision procedure, patients are typically monitored for any immediate complications, such as excessive bleeding or infection. Instructions for post-operative care will be provided, which may include keeping the surgical site clean and dry, monitoring for signs of infection, and managing pain with prescribed medications. Follow-up appointments may be necessary to assess the healing process and to discuss the results of the histologic evaluation. Patients should be advised to avoid strenuous activities that could stress the surgical site during the initial recovery period.

XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
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).
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.
73 Discontinued out-patient hospital/ambulatory surgery center (asc) procedure prior to the administration of anesthesia: due to extenuating circumstances or those that threaten the well being of the patient, the physician may cancel a surgical or diagnostic procedure subsequent to the patient's surgical preparation (including sedation when provided, and being taken to the room where the procedure is to be performed), but prior to the administration of anesthesia (local, regional block(s) or general). under these circumstances, the intended service that is prepared for but cancelled can be reported by its usual procedure number and the addition of modifier 73. 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.
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.
