Summary & Overview
CPT 42870: Lingual Tonsillectomy at Base of Tongue
CPT code 42870 captures the surgical removal or destruction of lingual tonsils at the base of the tongue, a procedure performed when hypertrophic lingual tonsils narrow the airway or cause obstructive symptoms. Nationally, this code is relevant to otolaryngology surgical services, ambulatory surgery centers, and hospital outpatient departments dealing with airway obstruction, sleep-disordered breathing, or recurrent infections linked to lingual tonsil hypertrophy. Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will find a concise clinical context for CPT code 42870, the typical service setting and procedural intent, and the principal payers that commonly reimburse or adjudicate claims for this service. The publication summarizes benchmark considerations, coding guidance essentials, and policy and coverage themes that affect authorization, site-of-service determination, and reimbursement. Where specific payer or diagnosis data are not provided in the input, the report notes that those details are not available and focuses on nationally relevant coding and clinical implications for billing workflows and payer interactions.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult or adolescent presenting with symptomatic lingual tonsil hypertrophy causing oropharyngeal obstruction, chronic throat clearing, dysphagia, snoring, or obstructive sleep apnea symptoms despite conservative management. The patient often has a history of persistent throat foreign-body sensation, recurrent infections or failed medical therapy (humidification, topical steroids, antibiotics). Evaluation includes otolaryngology consultation, flexible fiberoptic nasopharyngoscopy to visualize the base of tongue, airway assessment, and imaging if indicated. Surgical planning involves preoperative anesthesia assessment for potential difficult airway, informed consent discussing risks (bleeding, infection, airway edema), and selection of technique for excision or ablation of lingual tonsils under general anesthesia with endotracheal intubation. Intraoperative steps include exposure of the base of tongue (using tongue retraction and suspension), identification of hypertrophic lingual tonsillar tissue, and removal or destruction via cold knife excision, electrocautery, coblation, microdebrider, or laser. Hemostasis is secured, and the patient is observed postoperatively for airway compromise, pain control, and possible overnight monitoring. Typical site of service is an operating room in an ambulatory surgical center or hospital inpatient setting when airway risk is higher. Service type is surgical — excision/destruction of lingual tonsils (42870).
