Summary & Overview
CPT 42450: Sublingual Gland Excision
CPT code 42450 denotes the surgical excision of the sublingual gland, a procedure used to treat chronic salivary gland disease, obstructive sialadenitis, or neoplasms involving the sublingual space. As a defined procedural code in the CPT system, 42450 is important for accurate clinical documentation, coding, and national reporting of head and neck surgical services. Proper use of this code affects hospital and ambulatory surgery center billing, claims adjudication, and aggregate procedure utilization metrics across payers. Key payers in national analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. This publication provides: an operational summary of the procedure and typical sites of service; payment and utilization benchmarks across major payers; common billing and documentation considerations tied to procedure coding; and clinical context explaining indications and care settings. Readers will gain clarity on where 42450 fits within surgical service lines, how it is reported in claims, and what typical care settings look like for patients undergoing sublingual gland excision. Data not available in the input where specific payer rates, ICD-10 links, or related code mappings would normally appear.
Billing Code Overview
CPT code 42450 describes the surgical removal of the sublingual gland. This procedure is typically performed by an otolaryngologist, oral and maxillofacial surgeon, or head and neck surgeon.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult presenting with persistent sublingual swelling, recurrent mucous retention (ranula), chronic infection, or painful mass beneath the tongue that has failed conservative management. The workflow begins with an otolaryngology or oral and maxillofacial surgery clinic evaluation including history, oral exam, and imaging (ultrasound or CT/MRI) to assess gland size, ductal obstruction, and relation to surrounding structures. Preoperative counseling addresses anesthesia (local with sedation or general), risks (bleeding, infection, nerve injury), and alternatives. On the day of service the patient is prepared in an ambulatory surgical center or hospital outpatient operating room; regional or general anesthesia is administered. The surgeon performs an intraoral approach to excise the sublingual gland, achieves hemostasis, inspects for adjacent duct or nerve injury, and closes mucosal incisions. Postoperative care includes short-term oral antibiotics as indicated, analgesia, instructions for oral hygiene, and a follow-up visit to assess healing and remove sutures if needed. Typical sites of service are the ambulatory surgical center or hospital outpatient department. Common clinical scenarios include symptomatic ranula excision, recurrent sialadenitis of the sublingual gland, or space-occupying lesions requiring removal.
