When billing a procedure with a 0 global, can you bill E/M the following day? I seem to remember that these procedures (ie: cystoscopy-52000) have a zero global, but when billing E/M for follow-up care, Medicare will not pay for 10 days. Did I dream this? I know I've read something to this effect, but today I cannot, for the life of me, find it on the CMS site. Anyone know? Thanks.
