[Hockenberry]

A resident had a qualifying hospital stay and admittted to an SNF; after 65 days D/C to hosp (D/C return anticipated); for short stay (no new 3 day hospital stay); then admitted to a different SNF. Resident is still needs skilled care. May resident resume Medicare to use remaining days??OR is the resident no longer eligible for Medicare and why? Thanks!
