CPT code 93595 represents a diagnostic cardiac catheterization in which a catheter is navigated through blood vessels and advanced into the left side of the heart to evaluate congenital heart defects. This procedure is a key tool for defining left-sided anatomy and hemodynamics in patients born with structural heart anomalies and informs both medical management and procedural planning. Nationally, accurate coding and clinical documentation for left-sided cardiac catheterization affect claims processing, utilization tracking, and quality measurement for congenital heart disease care.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for the procedure, expected sites of service, and the typical service classification. The publication also outlines benchmarking and reimbursement context where available, common billing modifiers associated with interventional procedures, and potential coding considerations relevant to congenital heart disease evaluation. This material is written for clinicians, coding professionals, and policy analysts who need a concise reference to CPT code 93595, its clinical purpose, and implications for national billing and coverage practices.
