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.
