Summary & Overview
CPT 31612: Transtracheal Aspiration or Injection
CPT code 31612 represents percutaneous transtracheal airway intervention — either transtracheal aspiration to remove secretions or transtracheal injection of medication. This procedure addresses acute airway obstruction from secretions or the need for direct tracheal drug delivery and is clinically important for emergent airway management and targeted therapy. Nationally, the code is relevant to hospital-based care, emergency and critical care clinicians, and payers managing acute respiratory and airway procedures.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of clinical indications and typical sites of service, an overview of payer coverage considerations and common modifiers seen with this service, and context to interpret billing and coding for airway-directed transtracheal procedures. The publication highlights benchmarks and coding guidance where available and notes when input data is incomplete. This summary is intended for clinicians, coding professionals, and policy analysts seeking a national view of CPT code 31612.
Billing Code Overview
CPT code 31612 describes a procedure in which the provider punctures the trachea (windpipe) and either performs a percutaneous transtracheal aspiration to remove secretions or injects medication directly into the trachea. This procedure is an airway-directed intervention used to clear obstructing secretions or deliver drugs through a transtracheal approach.
-
Service type: Percutaneous transtracheal aspiration or transtracheal medication injection
-
Typical site of service: Procedure is typically performed in settings equipped for airway procedures, such as the hospital (emergency department, intensive care unit), and procedural suites where airway management and monitoring are available.
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult presenting to the emergency department or pulmonology clinic with retained tracheal secretions, suspected lower airway infection, or acute respiratory compromise with inability to clear secretions. The patient may have an intact upper airway but inadequate cough due to neuromuscular weakness, decreased consciousness, or chronic tracheostomy-related buildup. A clinician (emergency physician, pulmonologist, or ENT surgeon) explains the need for a targeted transtracheal aspiration or injection. The procedure is performed at bedside or in a procedure room: local anesthesia is applied to the skin and tracheal mucosa, a percutaneous puncture of the trachea is made using a sterile needle, aspiration is performed to remove mucus or purulent secretions for diagnostic culture and symptomatic relief, or a medication (for example, topical anesthetic or mucolytic) is instilled directly into the trachea. After the procedure the clinician monitors respiratory status, documents indication, technique, amount and character of secretions (if aspirated), any medication and dose instilled, patient tolerance, and any immediate complications. Typical billing reflects a single transtracheal aspiration or instillation under CPT code 31612 with site of service commonly as an emergency department, inpatient bedside, or outpatient procedure room depending on clinical urgency and setting.
