Is it appropriate to charge 94150 for ventilator weans? If not, what should be charged?
Weaning parameters or weaning procedures are inherent in ventilation management. There is not a separately billable CPT® code for weaning the patient. The cost for ventilation management is captured in the daily charge that is represented by the following initial day and subsequent day CPT codes:
In addition to the American Medical Association’s CPT code definitions, a hospital would refer to the American Hospital Association (AHA) guidelines that address the definition of time associated with mechanical ventilation, which state the following:
|94002||Ventilation assist and management, initiation of pressure or volume preset ventilators for assisted or controlled breathing; hospital inpatient/observation, initial day|
|94003||each subsequent day|
“Mechanical ventilation start time, duration, and end time is specifically defined in the official coding guidelines. Mechanical ventilation duration includes the time the patient is on the ventilator and the weaning period. Review the guidelines for various examples of when mechanical ventilation start time occurs. Stop time occurs when the mechanical ventilation is turned off and the weaning period is complete.” (AHA Coding Clinic on ICD-9-CM, Fourth Quarter 1992, pages 16–21, Third Quarter 2010, pages 3 and 4)
