Summary & Overview

CPT 42860: Removal of Tonsillar Remnants and Polyps

CPT code 42860 denotes a targeted surgical procedure to remove polyps and residual tonsillar tissue that remain after an initial tonsillectomy. This code captures revisionary otolaryngology surgery focused on excision of tonsillar remnants and associated lesions. Nationally, accurate reporting of this code ensures appropriate classification of follow-up surgical care distinct from primary tonsillectomy, and supports consistent tracking of post-operative interventions in otolaryngology practice.

Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, typical sites of service, and an outline of where this code fits in surgical billing workflows. The publication summarizes common billing practices, where benchmarks are available, and relevant policy or coding guidance updates that affect reporting of revision tonsillar procedures.

The content highlights clinical indications for the procedure, coding considerations for distinguishing primary versus secondary tonsillar surgery, and the operational context for billing and reimbursement. Data not available in the input is noted where applicable.

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult or adolescent who previously underwent a tonsillectomy but presents with persistent or recurrent symptoms from residual tonsillar tissue, such as throat discomfort, recurrent infections, or visible tonsillar remnants with polypoid overgrowth. The patient often reports several months to years of intermittent sore throat, halitosis, or recurrent tonsillitis localized to the tonsillar bed. Physical exam identifies small residual tonsillar pillars or polypoid tissue visible on oropharyngeal inspection.

Pre-procedure workflow includes history and focused head and neck exam, confirmation of prior tonsillectomy in the record, informed consent specific to removal of tonsillar remnants, and preoperative anesthesia assessment. The procedure is commonly performed in an ambulatory surgical center or hospital outpatient department under local anesthesia with sedation or general anesthesia depending on patient comfort, age, and airway considerations. Intraoperative technique involves visualization of the tonsillar fossa, excision of polypoid tissue or residual tonsillar fragments with surgical instruments (snare, curette, or microdebrider), hemostasis, and post-operative observation for airway compromise or bleeding. Typical post-operative care includes short observation, analgesia, and discharge instructions with return precautions for hemorrhage or infection.
