Summary & Overview
CPT 31531: Direct Laryngoscopy with Removal of Laryngeal Foreign Body
CPT code 31531 represents direct laryngoscopy with removal of a foreign body from the larynx using forceps, often aided by an operating telescope or microscope for visualization. This procedure is clinically important because retained foreign bodies in the larynx can cause airway compromise, infection, voice changes, or aspiration risk, making timely diagnosis and removal essential. Nationally, CPT code 31531 is relevant across hospital-based and specialty otolaryngology settings and intersects with acute care, emergency, and operative scheduling policies.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for CPT code 31531, typical sites of service, common billing considerations, and where to look for related documentation and coding guidance. The publication summarizes benchmark considerations and policy implications relevant to national payers, highlights coding relationships and potential claim scenarios, and clarifies the procedural scope of the code. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 31531 describes direct laryngoscopy with removal of a foreign body from the larynx using forceps. The procedure involves visualization of the larynx (voice box) with a laryngoscope and may use an operating telescope or microscope to visualize difficult or hidden foreign bodies.
-
Service type: Diagnostic and therapeutic endoscopic procedure involving foreign body removal from the larynx
-
Typical site of service: Operating room or procedure room where endoscopic equipment and microscopic visualization are available
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult or pediatric individual presenting to the emergency department, urgent care, or otolaryngology clinic with sudden-onset hoarseness, stridor, dysphagia, throat pain, or a choking event and suspected laryngeal foreign body. Initial evaluation includes airway assessment, pulse oximetry, and brief history (mechanism, time since aspiration, possible object type). Radiographic imaging (neck/chest X-ray) may be obtained if the object is radiopaque or if airway compromise is not immediate. When direct visualization and removal are required, the patient is taken to an operating room or procedure suite. Under general anesthesia with endotracheal tube or appropriate airway management, the provider performs direct laryngoscopy using a rigid laryngoscope and employs forceps to extract the foreign body. An operating telescope or operative microscope may be used for enhanced visualization of hidden fragments. Post-procedure assessment includes airway patency confirmation, monitoring in recovery, and discharge instructions or admission if airway edema or complications occur. Typical site of service: operating room, ambulatory surgery center, or emergency department procedure room depending on urgency and anesthesia needs.
