2025 CPT code 99192
(Active) Effective Date: N/A Revision Date: N/A Medicine - Other Medicine Services and Procedures Medicine Services and Procedures Feed
Assembly and operation of a pump with oxygenator or heat exchanger (with or without ECG and/or pressure monitoring); 30 minutes.
Modifiers may apply depending on the circumstances of the service (e.g., 53 - discontinued procedure, 76/77 - repeat procedure). Consult the CPT codebook and payer guidelines for specific modifier application rules.
Medical necessity for code 99192 is established when a patient requires cardiopulmonary bypass (CPB) during a surgical procedure.CPB is medically necessary to support vital functions during procedures that compromise the heart and lungs, such as complex cardiac surgeries or major vascular repairs, when maintaining adequate blood flow and oxygenation is critical for patient survival.
The provider is responsible for the assembly, operation, and management of the pump-oxygenator or heat exchanger system. This includes preparing the equipment, testing its functionality, monitoring the patient's vital signs (if applicable), and ensuring the system operates safely and effectively throughout the procedure. The provider must be knowledgeable about the components and functioning of the system and should be equipped to troubleshoot any issues that arise.
In simple words: The doctor sets up and runs a machine that pumps and adds oxygen to a patient's blood outside their body for 30 minutes. This might include checking their blood pressure and heart rhythm. This machine helps during heart surgery.
The provider assembles and operates a mechanical pump-oxygenator or heat exchanger for the circulation and oxygenation of blood outside the body for 30 minutes. This may include monitoring the patient's blood pressure and performing an electrocardiogram (ECG). The system consists of interconnected devices that replace the heart and lungs, removing oxygen-deprived blood and replacing it with oxygen-rich blood.Key components include a pump (artificial heart), an oxygenator (artificial lungs), and a heat exchanger. The provider prepares, tests, and manages the entire system, ensuring sterility, proper assembly, functionality of all components, and availability of backup supplies.Monitoring of blood pressure, temperature, and ECG may be included.
Example 1: During a complex cardiac surgery, the surgeon requires cardiopulmonary bypass (CPB). The perfusionist (the provider billing 99192) assembles and operates the heart-lung machine (pump-oxygenator), carefully monitoring blood flow, oxygenation, and temperature. The procedure lasts approximately 30 minutes., A patient undergoing a major vascular surgery experiences significant blood loss. The surgical team initiates CPB. The perfusionist manages the CPB circuit for 30 minutes, adjusting flow rates and monitoring the patient's hemodynamics to maintain stable physiological parameters., A patient with congenital heart defects undergoes a complex cardiac repair procedure. The perfusionist assembles and manages the pump-oxygenator system for 30 minutes during the cardiopulmonary bypass phase of the surgery, ensuring optimal blood oxygenation and flow to support the surgical team's work.
Complete documentation should include:
** This code is primarily used by perfusionists.Accurate timing is crucial; if the procedure extends beyond 30 minutes, additional codes may be needed.Payer-specific policies should always be consulted for proper coding and reimbursement guidelines.This code might be used in conjunction with other CPT codes representing the surgical procedure itself.
