hospital observation

Patient is all of different dates ... Observation admith level 3, observation subsequent level 3, observation discharge ... Do I bill 99220, 99233, 99217 ... Is this correct... Or how do I bill these charges?

observation

The "Observation" codes are outpatient codes, can only be billed once on day of admission. The admitting physician bills appropriate level based on medical necessity (99218-99220). If patient is in multiple days before discharge, code using 99212-99215, as documented. The day of discharge to home is code 99217.

Also note...

that middle day would rarely be a high level visit (use office visit codes not hospital codes as Nancy pointed out) since this is a patient who is unlikely to require high level decision making when they are being observed for response to therapy. And since you are held to outpatient standards, it is unlikely the doc will record the full 9 ROS or the full PE. So a 99214 would be the highest code I could envision.
