Official Description

Destruction of lesion(s), anus (eg, condyloma, papilloma, molluscum contagiosum, herpetic vesicle), simple; chemical

Common Language Description

The CPT® Code 46900 refers to the procedure for the destruction of lesions located in the anal region, which may include various types of growths such as condyloma, papilloma, molluscum contagiosum, and herpetic vesicles. This procedure is categorized as a simple chemical destruction method, where the physician employs a chemical agent, such as silver nitrate or another suitable compound, to eliminate the lesion. The process begins with a thorough examination of the lesion to determine the most effective destruction method. Depending on the specific characteristics of the lesion and the patient's needs, alternative techniques such as electrodessication, cryosurgery, laser surgery, or surgical excision may also be considered. Local anesthesia is typically administered to ensure patient comfort during the procedure. The choice of destruction method is crucial, as it impacts the effectiveness of the treatment and the recovery process. The procedure is designed to be straightforward, focusing on the safe and effective removal of anal lesions while minimizing discomfort and promoting healing.

1. Indications

The procedure described by CPT® Code 46900 is indicated for the treatment of various anal lesions. These include:

  • Condyloma - A type of wart caused by human papillomavirus (HPV) that can appear in the anal region.
  • Papilloma - Benign tumors that can develop in the anal area, often appearing as small, wart-like growths.
  • Molluscum contagiosum - A viral infection that results in raised, pearl-like lesions on the skin, which can occur around the anus.
  • Herpetic vesicle - Fluid-filled blisters caused by the herpes simplex virus, which can manifest in the anal area.

2. Procedure

The procedure for CPT® Code 46900 involves several key steps to ensure effective destruction of the anal lesions:

  • Step 1: Examination of the Lesion - The physician begins by carefully examining the anal lesion to assess its size, type, and characteristics. This evaluation is critical in determining the most appropriate method of destruction.
  • Step 2: Administration of Local Anesthesia - To minimize discomfort during the procedure, local anesthesia is administered to the patient. This step is essential for ensuring that the patient remains comfortable throughout the treatment.
  • Step 3: Chemical Application - The physician applies a chemical agent, such as silver nitrate, directly to the lesion. This chemical works to destroy the tissue of the lesion through a process of coagulation and necrosis.
  • Step 4: Monitoring and Follow-Up - After the chemical application, the physician monitors the area for any immediate reactions. Follow-up care may be discussed to ensure proper healing and to address any potential complications.

3. Post-Procedure

Post-procedure care for patients undergoing CPT® Code 46900 typically includes instructions on wound care and signs of potential complications. Patients may be advised to keep the area clean and dry, and to avoid any activities that could irritate the site of the lesion. It is important for patients to monitor for any signs of infection, such as increased redness, swelling, or discharge. Follow-up appointments may be scheduled to assess healing and to determine if further treatment is necessary. Overall, the recovery process is generally straightforward, with most patients experiencing minimal discomfort and a quick return to normal activities.

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.
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.
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.)
