If a patient becomes critical during an inpatient stay, physician wise, critical care and hospital codes can be charged on the same date of service correct? example - patient with pneumonia vs malignancy develops significant hypoxia with O2 titrating from 4 to 15 liters with non-re-breather. This occured on inpatient day 2, thoracentesis was performed, and patient was ultimately transferred to higher level of care elsewhere.

What about charging for critical care for the facility? Can this be seperately charged in the inpatient setting as well? or can you only charge the room rate even if the patient becomes critically ill requiring extensive care from nursing/ancillary staff?
