	CCW FIELD SOURCE AND DERIVATION:
	  RIC-X; Field Name: BENE_MDCR_STUS_CD

	  This field is determined either by the most recently recorded 
	  Medicare Status Code (MSC) history found for the beneficiary on 
	  the UEDB prior to the end of the reference year or date of death 
	  if the beneficiary died during the reference year, or it is derived 
	  from the Beneficiary Age and ESRD Indicator.  The following ordered 
	  rules determine the value for this field:

	  (1) If there was recorded MSC history, then the MSC of the most 
	      recently recorded history (prior to the end of the reference year 
	      or date of death if the beneficiary died during the reference 
	      year) gives the value for this field
	  (2) If no recorded MSC history was found from the UEDB, then:
   	      (a) If Beneficiary's Age >= 65, then MSC = '10'
	      (b) If Beneficiary's Age < 65, then MSC = '20'
	      (c) If ESRD Indicator = 'Y', then the 2nd digit becomes a '1' 
		  (e.g., '10' becomes '11', '20' becomes '21')
	  (3) If Beneficiary's Age >= 65 and the 1st digit of this field is 	
	      a '2' or '3', then the 1st digit is changed to '1' (e.g., '20' 
	      becomes '10')
	  (4) If Beneficiary's Age < 65 and the 1st digit of this field is a 
	      '1', then the 1st digit is changed to '2' (e.g., '10' becomes 
	      '20', '11' becomes '21')
