Official Description

Submucous resection inferior turbinate, partial or complete, any method

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 30140 refers to the procedure known as submucous resection of the inferior turbinate, which can be performed either partially or completely using any method. This surgical intervention is primarily aimed at alleviating nasal obstruction that arises due to the enlargement of the soft tissue or bone within the inferior turbinate. The inferior turbinate is one of three sets of turbinates, or conchae, located on each side of the nasal vestibule, specifically identified as inferior, middle, or superior based on their anatomical position. These turbinates consist of bony structures covered by a layer of spongy mucosa, which plays a crucial role in humidifying and filtering the air we breathe. The inferior turbinate is situated on the lower lateral wall of the nasal cavity, making it accessible through the nostril for surgical procedures. During the submucous resection, the physician first removes the outer layer of the turbinate mucosa, followed by the excision of part or all of the underlying turbinate bone. After this removal, the inner portion of the mucosa is folded over the surgical site and secured with sutures, promoting healing and minimizing complications. This procedure is essential for patients suffering from chronic nasal obstruction, enhancing their quality of life by improving airflow through the nasal passages.

1. Indications

The submucous resection of the inferior turbinate (CPT® Code 30140) is indicated for patients experiencing nasal obstruction due to the enlargement of the inferior turbinate. This condition may manifest as difficulty breathing through the nose, chronic nasal congestion, or other related symptoms that significantly impact the patient's quality of life. The procedure is typically considered when conservative treatments, such as medication or nasal sprays, have failed to provide adequate relief.

  • Nasal Obstruction The primary indication for this procedure is the presence of nasal obstruction caused by hypertrophy of the inferior turbinate.
  • Chronic Nasal Congestion Patients suffering from persistent nasal congestion that interferes with normal breathing may benefit from this surgical intervention.
  • Failure of Conservative Treatments The procedure is often indicated when non-surgical treatments have not yielded satisfactory results in alleviating symptoms.

2. Procedure

The submucous resection of the inferior turbinate involves several key procedural steps that ensure effective treatment of nasal obstruction. The procedure begins with the patient positioned appropriately to allow access to the nasal cavity. The physician then administers local anesthesia to minimize discomfort during the surgery. Following anesthesia, the physician approaches the inferior turbinate through the nostril, where the outer layer of the turbinate mucosa is carefully excised. This step is crucial as it exposes the underlying bone of the turbinate. Once the mucosa is removed, the physician proceeds to resect part or all of the turbinate bone, depending on the extent of the enlargement and the specific needs of the patient. After the bone removal, the inner layer of the mucosa is folded over the surgical site, covering the exposed area. This flap is then secured in place with sutures to promote healing and minimize the risk of complications. The entire procedure is designed to restore normal airflow through the nasal passages while preserving as much of the turbinate structure as possible.

  • Step 1: Anesthesia Administration The procedure begins with the administration of local anesthesia to ensure patient comfort during the surgery.
  • Step 2: Accessing the Inferior Turbinate The physician approaches the inferior turbinate through the nostril to prepare for the resection.
  • Step 3: Mucosal Excision The outer layer of the turbinate mucosa is excised to expose the underlying bone.
  • Step 4: Bone Resection The physician removes part or all of the turbinate bone, depending on the severity of the obstruction.
  • Step 5: Mucosal Flap Creation The inner layer of the mucosa is folded over the surgical site and secured with sutures.

3. Post-Procedure

After the submucous resection of the inferior turbinate, patients are typically monitored for a short period to ensure there are no immediate complications. Post-procedure care may include instructions for nasal hygiene, such as saline rinses, to keep the nasal passages moist and promote healing. Patients may experience some swelling and discomfort in the nasal area, which can be managed with prescribed pain relief medications. It is essential for patients to follow up with their physician to assess the healing process and address any concerns. Full recovery may take several weeks, during which patients are advised to avoid strenuous activities and refrain from blowing their noses to prevent disruption of the surgical site. Overall, the procedure aims to provide significant relief from nasal obstruction and improve the patient's overall respiratory function.

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).
50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
RT Right side (used to identify procedures performed on the right side of the body)
LT Left side (used to identify procedures performed on the left side of the body)
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.
