Official Description

Excision or destruction (eg, laser), intranasal lesion; external approach (lateral rhinotomy)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 30118 involves the excision or destruction of an intranasal lesion using an external approach known as lateral rhinotomy. An intranasal lesion refers to any abnormal tissue growth located within the nasal cavity, which may require surgical intervention for removal or destruction. The lateral rhinotomy approach is characterized by an incision that begins just below the inner aspect of the eyebrow and extends down along the lateral wall of the nose, ultimately reaching the nasolabial fold and encircling the alar margin. This method allows for direct access to the nasal cavity, facilitating the excision or destruction of the lesion. Prior to the procedure, the area is typically cleansed, and local anesthesia is administered to ensure patient comfort. The surgical technique may involve various methods for lesion removal, including excision with a margin of healthy tissue or destruction through techniques such as cryosurgery, electrosurgery, or laser treatment. The choice of technique depends on the specific characteristics of the lesion and the surgeon's assessment. Following the procedure, the excised lesion is often sent for histologic evaluation to determine its nature and ensure appropriate management.

1. Indications

The procedure described by CPT® Code 30118 is indicated for the excision or destruction of intranasal lesions that may present various symptoms or conditions requiring surgical intervention. These indications may include:

  • Presence of Intranasal Lesions Lesions within the nasal cavity that may be benign or malignant and require removal for diagnostic or therapeutic purposes.
  • Obstruction of Nasal Airway Lesions that cause blockage or obstruction of the nasal passages, leading to difficulty in breathing or other respiratory issues.
  • Recurrent Nasal Symptoms Patients experiencing recurrent nasal symptoms such as chronic sinusitis, nasal congestion, or persistent nasal discharge that may be attributed to the presence of a lesion.
  • Cosmetic Concerns Lesions that may cause aesthetic concerns for the patient, prompting the need for surgical intervention to improve appearance.

2. Procedure

The procedure for CPT® Code 30118 involves several detailed steps to ensure the effective excision or destruction of the intranasal lesion. The steps are as follows:

  • Step 1: Preparation The surgical site is prepared by cleansing the area thoroughly to minimize the risk of infection. Local anesthesia is then administered to ensure the patient remains comfortable throughout the procedure.
  • Step 2: Incision An incision is made beginning just below the inner aspect of the eyebrow. This incision descends along the lateral wall of the nose and continues to the nasolabial fold, where it is carried around the alar margin. This approach provides optimal access to the nasal cavity.
  • Step 3: Dissection Soft tissue is carefully dissected and freed from surrounding structures, including the ethmoid bone, anteromedial antral wall, and the nasal pyramid. This dissection is crucial for exposing the nasal cavity and the lesion.
  • Step 4: Lesion Management Once the nasal cavity is exposed, the lesion is examined. Depending on its characteristics, the surgeon may choose to excise the lesion with a margin of healthy tissue or employ destruction techniques such as cryosurgery, electrosurgery, or laser treatment.
  • Step 5: Hemostasis After the lesion is excised or destroyed, any bleeding is controlled using electrocautery or chemical cautery to ensure a clean surgical field.
  • Step 6: Closure The surgical site may be left open to heal naturally or closed using a simple single-layer suture technique, depending on the extent of the procedure and the surgeon's preference.

3. Post-Procedure

Post-procedure care for patients undergoing CPT® Code 30118 includes monitoring for any signs of complications such as excessive bleeding or infection. Patients are typically advised on wound care, which may involve keeping the area clean and dry. Follow-up appointments may be scheduled to assess healing and to review the histologic evaluation results of the excised lesion. Patients may also receive instructions regarding pain management and activity restrictions to promote optimal recovery.

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.
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.)
