There are two codes for ventilator management for inpatient services: 94002 and 94003.  One is for the day when the physician initiates vent management and the second is for a subsequent day. They are mutually exclusive codes in the CCI edits and may not be billed together on the same day.   See the CPT® book for the complete description of these two codes.

Both are active codes, and have total RVUs of 2.43 and 1.76 respectively.

These codes should be used when ventilator management is the service provided by the physician.  If the physician is also providing other critical care services, bill only for the critical care.  These codes are bundled into 99291 and may not be reported (and will not be paid) separately.

Ventilator management is also bundled into the other hospital E/M  codes: the physician may not report and will not be paid for vent management and initial or subsequent hospital visits on the same day.
