CPT code 33300 designates surgical repair of a wound to the heart performed without cardiopulmonary bypass. This procedure is used to control bleeding or close myocardial lacerations when CPB is not required or feasible. Nationally, the code captures an acute cardiac operative service with implications for inpatient surgical workflows, coding specificity, and emergent cardiac care capacity.

Key payers covered in typical analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. These payers commonly influence coverage policies, prior authorization pathways, and payment determinations for high-acuity cardiac procedures.

Readers will find concise clinical context for when the code is used, typical sites of service, and the service type. The publication also outlines the scope of benchmarking and policy elements typically associated with cardiac operative codes: payer coverage considerations, documentation and coding precision required for emergent cardiac repairs, and how this code fits in with related cardiac surgery procedure coding.
