Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 33948 covers

This service covers a physician’s ongoing management of venovenous extracorporeal membrane oxygenation or extracorporeal life support. Venovenous support drains blood from and returns it to the venous circulation, typically to provide oxygenation and carbon dioxide removal in severe respiratory failure. Intensivists, cardiothoracic surgeons, and other physicians directing ECMO care may perform this work in an intensive care setting. Management may include assessing the patient’s response, reviewing circuit function and relevant clinical data, and directing changes to support settings or treatment.

Report 33948 for a date on which the physician provides daily management while venovenous support is ongoing; it is not the code for starting support or placing cannulas. Documentation should identify the venovenous configuration and date, and describe the physician’s management work, such as assessment of the patient and circuit and decisions about continued support or adjustments. The service is distinct in purpose from the initial setup and cannulation procedures.
