 unit count associated with accommodation revenue center
 code 021x (all six subcategories) from all claim
 records included in the stay.
  
 SOURCE         : NCH
  
 LIMITATIONS :
 There is approximately a 20% error rate in the revenue
 center code category 0214 due to coders misunderstanding
 the term 'post ccu' as including any day after a ccu
 stay rather than just days in a step-down/lower case
 version of a ccu.  'Post' was removed from the
 revenue center code 0214 description, effective
 10/1/96 (12/96 MEDPAR update).  0214 Is now defined
 as 'intermediate ccu'.
