Hospitalist in Facility A treats inpatient for several days then determines pt needs to be transferred to Facility B (these 2 facilities are related / part of the same health system). On the day of transfer, only 1 subsequent visit E&M code can be billed. The question is, who gets to bill for the service? Is it billed under the transferring hospitalist or the receiving hospitalist? Facility A can not bill a discharge E&M and Facility B can not bill an admit E&M. Only 1 of these facilities can bill the subsequent visit code. Which one is it? I have reviewed the CMS E&M manual and can not find any specific guideline as to which facility gets to bill, only that 1 subsequent code can be billed and to combine the services of both facilities to determine the highest level.
