About 33948: Venovenous ECMO daily management
Report this service for a physician’s ongoing daily management of venovenous ECMO supporting a patient with severe respiratory failure.
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.

33948 billing questions
How does 33948 differ from 33946?
33946 describes initiation of venovenous ECMO/ECLS. Use 33948 for the physician’s ongoing daily management after support has been initiated.
When should 33949 be used instead?
33949 is for daily management of arterial ECMO/ECLS. Select 33948 when the support configuration is venovenous.
Does 33948 include cannula placement?
No. The daily management service concerns ongoing physician oversight; cannula insertion is described by separate cannulation codes when that procedure is performed.
How often is 33948 reported?
It represents daily management, so documentation should support the physician’s work for the date reported rather than counting individual circuit adjustments as separate services.
What documentation supports 33948?
Document the venovenous configuration, date of management, patient and circuit assessment, and the physician’s decisions or direction regarding ongoing ECMO support.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
