Summary & Overview
CPT 93595: Left-Sided Diagnostic Cardiac Catheterization for Congenital Heart Defect
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.

Billing Code Overview
CPT code 93595 describes a diagnostic cardiac catheterization procedure performed in patients born with one or more congenital heart defects. During the procedure, the clinician navigates a catheter through the vascular system to the heart and places the catheter into the left side of the heart for targeted evaluation. The description indicates invasive cardiac access and direct assessment of left-sided cardiac structures.
Service type: Diagnostic cardiac catheterization, left-sided access for congenital heart disease evaluation
Typical site of service: Cardiac catheterization laboratory or specialized interventional cardiology suite
Clinical & Coding Specifications
Clinical Context
A typical patient is a neonate or infant born with congenital heart disease (for example, ventricular septal defect, transposition of the great arteries, or suspected left-sided obstructive lesion) who requires diagnostic left heart catheterization to define intracardiac anatomy, measure pressures, and assess pulmonary and systemic blood flow. The clinical workflow includes pre-procedure evaluation (history, focused cardiology physical exam, echocardiography review, labs and informed consent), transport to the cardiac catheterization laboratory, general anesthesia or sedation per pediatric anesthesia, vascular access (typically femoral arterial and venous access), catheter navigation across the aortic valve or via retrograde arterial approach into the left heart chambers, hemodynamic pressure measurements, angiography as indicated, removal of catheters and hemostasis, and post-procedure monitoring in a pediatric recovery or cardiac ICU setting. Typical site of service is the hospital cardiac catheterization laboratory or pediatric cardiac catheterization suite. The service type is an interventional diagnostic cardiac catheterization targeted to the left heart for congenital heart defect evaluation.
