Inpatient Stay During Which Enrollment Ends

10.2.1 – Inpatient Stay During Which Enrollment Ends (Rev. 120, Issued: 01-16-15, Effective: 01-01-15, Implementation: 01-01-15) MAOs must continue to cover, through discharge, inpatient services of a non-plan enrollee if the individual was an enrollee at the beginning of the inpatient stay. Note that incurred non-inpatient services are paid by original Medicare or the new MAO the enrollee joined as of the effective date of the new coverage. Enrollee cost-sharing for the inpatient hospital stay is based on the cost-sharing amounts as of the entry date into the hospital. If the enrollee is in a SNF in December and in an MAO that does not require a prior qualifying 3-day hospital stay and then joins original Medicare on January 1, the stay continues to be considered a covered stay (if medically required).
