99217?
You cannot bill two ED codes for the reevaluation of the same condition on a single day. For the second service you need a different Dx. Code 99217 reports observation care discharge day management services when the patient is discharged on a date subsequent to the observation date. You have not mentioned if the patient was under observation and then discharged on a different date. So 99217 is not the right code here.
IF THE PATIENT WAS ADMITTED BY THE REEVALUATION FOR ANOTHER DR (NOT FOR SAME INITIAL DR EVALUATION)WHAT CODE I NEED TO USE?
Per your question: 1) Pt. was admitted (so, I assume that you're talking about Inpt. condition & not about under observation status / ER room status).
2)Pt. was seen in ER previously by a doc. and now Pt. is admitted by another doc. for re-evaluation.
If these are correct, then you should code 99221 - AI, for the initial evaluation (it could be re-evaluation of the Pt.'s condition, but now done in the Inpt. set up) done by the new admitting doc., in the Inpt. set-up. You need to append AI modifier to show that the service was provided by the admitting doc.
