CPT code 75825 denotes the supervision and interpretation of venography of the inferior vena cava with serialography — an invasive diagnostic imaging procedure using contrast to detect and localize venous thrombus. This service is clinically important for diagnosing suspected deep venous thrombosis involving the inferior vena cava, pre-procedural planning, and assessment when noninvasive imaging is inconclusive. Nationally, accurate coding and interpretation affect episode care decisions and utilization of advanced imaging resources.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of where this service is typically provided, common billing contexts, and benchmarking considerations for utilization and coverage. The publication also summarizes clinical context for use of invasive venography versus noninvasive alternatives, common modifiers associated with interpretation and technical components, and considerations for documentation and claim submission.
