Official Description

Assembly and operation of pump with oxygenator or heat exchanger (with or without ECG and/or pressure monitoring); each hour

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 99190 refers to the assembly and operation of a pump that is equipped with either an oxygenator or a heat exchanger. This procedure is typically performed by a physician and is crucial in various medical settings, particularly in situations requiring extracorporeal circulation, such as during certain surgical procedures or in critical care environments. The code encompasses the entire process of setting up and managing the pump, which may include monitoring the patient's heart activity through an electrocardiogram (ECG) and/or measuring blood pressure, although these monitoring functions are not mandatory for the procedure to be coded under 99190. It is important to note that this code is billed for each hour of service provided. For shorter durations of treatment, there are specific codes available: CPT® Code 99191 is used for treatment lasting three-quarters of an hour, while CPT® Code 99192 is designated for treatment lasting half an hour. This structured approach to coding ensures that healthcare providers are accurately reimbursed for the time and resources dedicated to patient care during these complex procedures.

1. Indications

The assembly and operation of a pump with an oxygenator or heat exchanger, as described by CPT® Code 99190, is indicated in various clinical scenarios where extracorporeal circulation is necessary. This may include, but is not limited to, the following conditions:

  • Cardiac Surgery Procedures that require temporary support of the heart and lungs during surgery.
  • Respiratory Failure Situations where patients need assistance with oxygenation and carbon dioxide removal.
  • Severe Trauma Cases where immediate circulatory support is required to stabilize the patient.

2. Procedure

The procedure for the assembly and operation of the pump with an oxygenator or heat exchanger involves several critical steps to ensure patient safety and effective treatment. Each step is essential for the successful implementation of the procedure:

  • Step 1: Preparation The physician prepares the necessary equipment, including the pump, oxygenator, or heat exchanger, ensuring that all components are sterile and functioning properly before use.
  • Step 2: Assembly The physician assembles the pump system, connecting the oxygenator or heat exchanger as required. This step may involve configuring the device to monitor ECG and blood pressure, depending on the clinical needs of the patient.
  • Step 3: Initiation Once assembled, the physician initiates the pump operation, carefully monitoring the patient’s vital signs and ensuring that the system is functioning correctly to provide adequate support.
  • Step 4: Monitoring Throughout the operation, the physician continuously monitors the patient’s condition, adjusting the pump settings as necessary to maintain optimal oxygenation and circulation.
  • Step 5: Documentation The physician documents the procedure, including the duration of pump operation and any relevant observations or adjustments made during the treatment.

3. Post-Procedure

After the assembly and operation of the pump with an oxygenator or heat exchanger, the physician must ensure proper post-procedure care. This includes monitoring the patient for any adverse reactions or complications that may arise from the use of the pump. The physician should assess the patient's vital signs and overall stability, providing additional support as needed. Documentation of the procedure and any follow-up care instructions is essential for continuity of care and for billing purposes. The expected recovery will depend on the underlying condition being treated and the duration of pump operation, with close observation required during the initial recovery phase.
