Summary & Overview
CPT 42505: Secondary or Complicated Repair of Salivary Gland
CPT code 42505 denotes a secondary or complicated surgical repair of an infected or damaged salivary gland. This code captures operative care for patients who require reoperation or complex reconstruction due to infection, prior failed repair, or significant glandular injury. Nationally, accurate use of this code is important for procedure-level reporting, resource planning in surgical specialties (otolaryngology, maxillofacial surgery), and claims adjudication where complexity and secondary intervention affect reimbursement and utilization metrics.
Key payers in typical analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for the procedure, typical sites of service, and expected documentation elements tied to complexity and secondary intervention. The publication also summarizes common modifiers and payer considerations, benchmark patterns where available, and policy implications for coding audits and medical necessity review. Clinical context covers indications for secondary repair, potential perioperative considerations, and the distinction between primary and secondary operative approaches.
This content is intended for national audiences including coding professionals, surgical clinicians, revenue cycle staff, and policy analysts seeking a clear reference for CPT code 42505 and its role in procedural reporting, coverage reviews, and operational planning.
Billing Code Overview
CPT code 42505 describes a secondary or complicated repair of an infected or damaged salivary gland. This procedure involves operative intervention to address persistent infection, structural damage, or functional compromise of a salivary gland after prior treatment or in the setting of complex pathology.
-
Service type: Surgical repair of a salivary gland, secondary or complicated
-
Typical site of service: Hospital operating room or ambulatory surgical center where operative management of infected or damaged salivary glands is performed
Clinical & Coding Specifications
Clinical Context
A 48-year-old male presents to the otolaryngology clinic with a chronic, recurrently infected right submandibular salivary gland following prior trauma and an earlier unsuccessful primary repair. He reports persistent swelling, pain with meals, intermittent purulent drainage, and periodic fever. Examination and imaging (ultrasound and contrast CT) demonstrate an irregular, partially necrotic submandibular gland with ductal stricture and abscess formation. The surgical team schedules a secondary or complicated repair of the salivary gland to excise infected tissue, repair or reconstruct the ductal anatomy as feasible, drain abscesses, and obtain cultures. The procedure typically occurs in an ambulatory surgery center or hospital OR under general anesthesia with intraoperative antibiotic administration, possible placement of a drain, and short postoperative observation. Postoperative workflow includes wound care instructions, culture-directed antibiotics, outpatient follow-up for drain removal and assessment of salivary function, and documentation of operative findings, complexity of prior surgery or infection, and any unplanned intraoperative events for coding and billing accuracy.
