HI 00401.275 Christian Science Sanatorium
   
   
   
   A Christian Science sanatorium operated or listed and certified by the First Church
      of Christ, Scientist, Boston, Mass., qualifies as both a hospital and SNF. Sanatorium
      services are considered to be furnished by a sanatorium in its capacity as a hospital
      unless the individual elects to have them treated as sanatorium extended care services.
      Inpatient care in such an institution whether as hospital services or extended care
      services can begin or prolong a “spell of illness” (benefit period, see HI 00401.340).
   
   
   Payment may not be made in the same benefit period for both sanatorium extended care
      and extended care services in a qualified SNF other than a Christian Science sanatorium.
      This limitation does not apply to hospital services. Payment for sanatorium extended
      care services is limited to 30 days in each benefit period.
