my question is-if a patient is here for Inpatient admission, we bill POS 21. If he leaves our facility to go to Dr.s office (different Tax ID POS 11) for services we can not provide. How does the Dr.s bill Medicare to receive payment and not denied as POS invalid. Im reading an MLN Matters # MM7631, and I am getting that POS should be billed as POS 21 as well. even if services were in office location. Under CR7631 tere is a section SPECIAL CONSIDERATIONS FOR SERVICES FURNISHED TO REGISTERED INPATIENTS.

Could someone please verify if im reading correctly, or explain if im not? thank you
