Summary & Overview
CPT 42600: Surgical Management of Salivary Fistula
CPT code 42600 denotes the surgical management of a salivary fistula, a clinical complication that can arise from trauma, infection, or prior procedures affecting salivary glands or ducts. Nationally, accurate coding for these procedures is important for clinical documentation, utilization tracking, and payer adjudication because salivary fistulae often require operative repair and possible multidisciplinary care.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, an outline of typical sites of service, and an explanation of why correct CPT coding matters for billing and claims processing. The publication also summarizes common modifiers associated with surgical services and identifies where gaps in input data exist.
This summary provides a practical reference for clinicians, coding professionals, and billing teams who need a clear depiction of the procedure represented by CPT code 42600, its typical care setting, and the national payer landscape relevant to reimbursement and claims review.
Billing Code Overview
CPT code 42600 describes management of a salivary fistula, a pathological connection between a salivary gland or duct and the skin or an internal mucosal surface that can result from injury or infection. The procedure addresses persistent abnormal saliva drainage that may require surgical intervention to close the tract and restore normal salivary flow.
Service type: Surgical management of salivary fistula
Typical site of service: Operative suite or ambulatory surgical center

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult who presents with a persistent salivary fistula after traumatic injury to the parotid or submandibular gland, or as a complication of infection or prior surgery in the parotid region. The patient often reports continuous clear or serous drainage from a cutaneous opening on the cheek or neck that increases with salivation or eating, associated intermittent swelling or discomfort, and occasional cellulitis of adjacent skin.
Initial clinical workflow includes history and targeted head and neck physical exam, documentation of drainage characteristics and fistula location, and assessment for active infection. Imaging such as ultrasound or CT with contrast, or fistulography, may be obtained to define the tract and gland involvement. After conservative measures (pressure dressings, anticholinergic medication, needle aspiration of collections, or botulinum toxin injection) fail or are contraindicated, surgical exploration and repair of the fistula is planned. The operative procedure typically involves identification of the fistulous tract, excision or debridement of epithelialized tract, reapproximation or diversion of salivary duct flow, possible gland excision if gland is diseased, layered closure of skin, and consideration of drain placement. Postoperative management includes wound care, short course antibiotics if infected, sialogogues avoidance, and follow-up for wound healing and recurrence assessment. Documentation required for coding includes operative note with 42600 procedure descriptor, laterality and approach, presence of gland excision if performed, intraoperative findings, estimated blood loss, and any concomitant procedures or modifiers applied.
