I have a patient who was admitted for a procedure with global (000). The E/M is generally included on day of procedure for global 000 but subsequent days can be billed. For this encounter I only billed the procedure. The patient was discharged the next day by the physician who did the procedure so I can bill for that physician since there is no global period. My question is can I use a discharge code since this was a discharge note even though I have no admit code to precede the discharge code?
