Summary & Overview

CPT 42844: Tonsil and Oropharyngeal Resection with Local Flap Closure

CPT code 42844 identifies an extensive surgical resection of tonsillar and adjacent oropharyngeal tissues, often including partial removal of the maxilla or mandible when involved, with wound closure using local tissue flaps. The code is used for oncologic resections in the oropharynx and reflects procedures that carry significant implications for operative planning, reconstruction, postoperative care, and reimbursement classification nationally. Key payers covered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare and Medicare. Readers will find a concise clinical description, the typical sites of service, and the common modifiers associated with billing for this procedure. The publication provides benchmarks and coding context relevant to hospital and ambulatory surgical settings, highlights clinical considerations for reconstruction after tumor excision, and summarizes payer coverage patterns and policy nuances where available. Data not available in the input is noted explicitly in sections where specific elements—such as associated taxonomies, related codes, or ICD-10 diagnoses—are required but absent.

Billing Code Overview

CPT code 42844 describes a surgical procedure in which the provider removes the tonsils, tonsillar pillars and/or the retromolar trigone. If required, portions of the maxilla or mandible that are affected are also excised, and the resulting wound is closed with local tissue flaps. This operation is commonly performed to resect cancerous growths in the oropharyngeal region.

Service type: Surgical resection of oropharyngeal structures with reconstruction using local tissue flaps
Typical site of service: Hospital operating room or ambulatory surgical center, depending on clinical complexity and need for inpatient care

Clinical & Coding Specifications

Clinical Context

A 62-year-old male presents with a biopsy-confirmed squamous cell carcinoma involving the tonsil and adjacent tonsillar pillar with suspected extension toward the retromolar trigone. After staging and multidisciplinary tumor board review, the patient is scheduled for surgical resection under general anesthesia. The planned operation includes wide local excision of the tonsil and involved tonsillar pillar and retromolar trigone, limited resection of involved portions of the mandible, and primary closure using local tissue flaps. Typical preoperative workflow includes imaging (CT/MRI), pre-anesthesia evaluation, informed consent discussing airway management and potential need for tracheostomy, mark-up of surgical margins, coordination with pathology for intraoperative frozen section, and arrangement for postoperative head and neck surgical nursing care and speech/swallow therapy. Typical postoperative workflow includes monitoring for airway compromise, pain control, wound care, nutritional support (enteral feeding as needed), pathology review of margins, and oncology follow-up for adjuvant therapy decisions. Typical site of service is an inpatient hospital operating room; ambulatory surgical center is uncommon for extensive resections with bone involvement. Service type is major head and neck oncologic resection with reconstructive closure using local tissue flaps.
