Summary & Overview
CPT 42120: Resection of Palatal Lesion, Wide Area
CPT code 42120 denotes surgical resection of a lesion over a wide area of the palate, a procedure typically undertaken for malignant neoplasms of the oral cavity. This code captures complex head and neck oncologic surgery with implications for operative planning, postoperative care, and hospital resource utilization. Nationally, accurate coding of palatal resections affects payment, quality reporting, and case-mix measurement for facilities and surgeons who treat head and neck cancers.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for palatal resection, typical settings of care, and the reimbursement and documentation considerations that commonly arise with this type of head and neck oncologic surgery. The publication covers benchmarked payment considerations across major payers, coding and billing nuances that influence claim acceptance, and operational impacts such as site-of-service designation and facility resource use. Where specific input data are not provided, the text notes that information is unavailable.
This summary is intended for health system coding leaders, surgical oncologists, reimbursement analysts, and policy staff who need a national-level briefing on the coding and clinical implications of CPT code 42120.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult referred to an otolaryngologist or oral/maxillofacial surgeon for resection of a suspected or confirmed malignant lesion of the hard or soft palate. The patient often presents with progressively enlarging palatal mass, ulceration, pain, bleeding, or difficulty with swallowing/speech. Preoperative workup includes head and neck examination, flexible nasopharyngoscopy, imaging (contrast-enhanced CT or MRI of the head and neck), and biopsy confirming malignancy (for example, squamous cell carcinoma). The clinical workflow: initial evaluation and biopsy by the surgeon or ENT, staging with imaging and possible dental/oral oncology consultation, preoperative medical clearance, operative resection of the lesion and involved palate with appropriate margins under general anesthesia, intraoperative frozen section evaluation as needed, reconstruction (local flap, free flap, or obturator) often performed in the same setting or staged, postoperative monitoring in PACU and inpatient setting, pathology review for margin status, and coordination of adjuvant radiation or chemoradiation with medical/radiation oncology if indicated. Typical site of service is an ambulatory surgery center or hospital operating room. Service type is major surgical resection of oral cavity/palatal malignant lesion under general anesthesia.
