CPT code 33289 covers the permanent implantation of a wireless sensor in the pulmonary artery during catheterization, including calibration and, when performed, right heart catheterization and pulmonary arteriography with radiological supervision and interpretation. This intervention enables continuous or intermittent hemodynamic monitoring of pulmonary artery pressures and has implications for chronic management of conditions such as heart failure and pulmonary hypertension. Nationally, the code matters because it captures an advanced implantable diagnostic service that intersects cardiology, interventional cardiology, and remote monitoring programs.

Key payers included in this overview are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise review of what the code represents clinically, an outline of typical service settings, and the payer landscape covered. The publication provides benchmarks and comparative coverage context, summaries of relevant policy and reimbursement considerations, and clinical context for when the service is typically used. Data elements not provided in the input—such as associated taxonomies, specific ICD-10 diagnoses, and related procedure codes—are noted as unavailable in the input. The content is intended for national audiences including clinicians, coding professionals, and policy analysts seeking a clear summary of CPT code 33289 and its role in monitoring pulmonary artery pressures.
