Official Description

Destruction, malignant lesion (eg, laser surgery, electrosurgery, cryosurgery, chemosurgery, surgical curettement), scalp, neck, hands, feet, genitalia; lesion diameter 0.5 cm or less

Common Language Description

The CPT® Code 17270 refers to the destruction of malignant lesions located on specific areas of the body, including the scalp, neck, hands, feet, and genitalia, where the diameter of the lesion is 0.5 cm or less. Malignant lesions of the skin can include various types of cancers such as basal cell carcinoma, squamous cell carcinoma, and malignant melanoma. The procedure involves a thorough examination of the lesion to determine the most suitable method of destruction. Depending on the case, a local anesthetic may be administered to ensure patient comfort during the procedure. Various techniques can be employed for the destruction of the lesion, including cryosurgery, which utilizes liquid nitrogen to freeze the lesion through a series of freeze-thaw cycles. Additionally, surgical curettage, which involves scraping away the lesion, may be followed by electrosurgery to ensure complete destruction. In cases where multiple lesions are present, alternative methods such as chemical or pharmacologic agents or laser resurfacing with a carbon dioxide laser may be utilized. It is important to note that during the destruction process, the physician not only targets the malignant lesion but also removes a surrounding border of normal tissue to minimize the risk of recurrence. For accurate coding, it is essential to use the appropriate CPT® code based on the size of the lesion, with 17270 specifically designated for lesions measuring 0.5 cm or less.

1. Indications

The procedure associated with CPT® Code 17270 is indicated for the treatment of malignant skin lesions that require destruction. The specific conditions or symptoms that may warrant this procedure include:

  • Basal Cell Carcinoma - A common type of skin cancer that often 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 or raised area on an old scar or ulcer.
  • Malignant Melanoma - A serious form of skin cancer that can develop from existing moles or appear as a new dark spot on the skin.

2. Procedure

The procedure for CPT® Code 17270 involves several key steps to ensure the effective destruction of the malignant lesion. These steps include:

  • Step 1: Examination of the Lesion - The physician conducts a thorough examination of the malignant lesion to assess its characteristics, including size, location, and type. This evaluation is crucial for determining the most appropriate method of destruction.
  • Step 2: Administration of Local Anesthetic - If necessary, a local anesthetic is administered to the patient to minimize discomfort during the procedure. This step is particularly important for lesions located in sensitive areas such as the scalp or genitalia.
  • Step 3: Selection of Destruction Method - The physician selects the most suitable method for lesion destruction based on the examination findings. Options may include cryosurgery, electrosurgery, surgical curettage, or the use of chemical agents.
  • Step 4: Execution of the Destruction - The chosen method is then executed. For cryosurgery, liquid nitrogen is applied to freeze the lesion, while electrosurgery involves the use of electrical currents to destroy the tissue. Surgical curettage involves scraping the lesion away, often followed by electrosurgery to ensure complete removal.
  • Step 5: Removal of Surrounding Tissue - During the destruction process, the physician also removes a margin of surrounding normal tissue to reduce the likelihood of cancer recurrence. This step is critical for ensuring that all malignant cells are eliminated.

3. Post-Procedure

After the procedure coded under CPT® 17270, patients may require specific post-procedure care to promote healing and monitor for any complications. This may include instructions on how to care for the treatment site, such as keeping it clean and dry, applying topical ointments as prescribed, and avoiding sun exposure. Patients should also be advised to watch for signs of infection, such as increased redness, swelling, or discharge. Follow-up appointments may be necessary to assess the healing process and ensure that the lesion has been adequately treated. Additionally, patients should be informed about the potential for scarring and the importance of regular skin checks to monitor for any new lesions or changes in existing moles.

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).
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.
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
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.

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.)
