CPT code 42104 denotes excision of a lesion from the palate or uvula without closure. The code captures a focused, limited soft-tissue surgical procedure in the oropharynx and is used across ambulatory surgical centers, hospital outpatient departments, and some office-based surgical settings. It matters nationally because accurate coding supports appropriate clinical documentation, procedure tracking, and payment for targeted oropharyngeal lesion removal.

Key payers in typical coverage analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. These payers commonly assess medical necessity, place-of-service, and documentation of lesion characteristics to determine coverage and claim adjudication. Common modifiers are listed in the provided input but are not discussed here in detail.

Readers will learn the clinical scope captured by the code, the typical settings where the procedure is performed, and how this code fits into surgical service lines for head and neck procedures. The publication provides benchmarks and policy-relevant context where available, explains documentation elements that affect coding and coverage, and outlines limitations when input data is missing.
