Hello- I'm looking for information on Critical Access Hospitals billing for E/M codes. A patient is seen in the ER and an ER E/M is billed on the UB form. Is the code subject to being included in services that have a global period (surgical services) much like the physician claim if services are billed on a 1500 form? CAH services are paid a little differently and I have seen some ER E/M services billed with a 25 modifier which makes me suspect that the E/M could be bundled into a surgical service or something with a global period. Finding specific information or guidance on this has been an issue. Any thoughts are much appreciated!
