Summary & Overview
CPT 31511: Laryngeal Mirror Exam with Foreign Body Removal
CPT code 31511 denotes a laryngeal mirror examination with direct removal of a foreign body from the larynx. This code captures a focused diagnostic visualization of the voice box combined with a minor operative maneuver to extract a foreign object. Nationally, the procedure is relevant across acute care, outpatient, and emergency settings because foreign bodies in the airway can present urgent clinical risk and require prompt intervention.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult or pediatric patient presenting to the clinic, urgent care, emergency department, or operating room with suspected laryngeal foreign body, acute dysphonia, throat pain, stridor, cough, or sensation of a lodged object. The workflow begins with a focused history and airway assessment, vital signs, and oxygenation. Topical or local anesthesia and appropriate monitoring are applied. The provider performs indirect laryngoscopy using a laryngeal mirror to visualize the larynx. If a foreign body is identified in the supraglottic or glottic region, the provider uses forceps to grasp and remove the object under direct visualization. Hemostasis is confirmed and airway patency reassessed. For children or uncooperative patients, the procedure may occur in the operating room under general anesthesia. Post-procedure monitoring focuses on airway stability, bleeding, voice change, and potential aspiration. Typical sites of service include outpatient clinic, emergency department, ambulatory surgical center, and hospital operating room.
