3. COUNTY CODE                  CHAR      3   

	THIS CODE SPECIFIES THE SSA CODE FOR THE
	COUNTY OF RESIDENCE OF THE BENEFICIARY.
	EACH STATE HAS A SERIES OF CODES BEGINNING
	WITH '000' FOR EACH COUNTY WITHIN THAT
	STATE.  CERTAIN CITIES WITHIN THAT STATE
	HAVE THEIR OWN CODE.   COUNTY CODES MUST
	BE COMBINED WITH STATE CODES IN ORDER TO
	LOCATE THE SPECIFIC COUNTY.  THE CODING
	SYSTEM IS THE SSA SYSTEM, NOT THE FEDERAL
	INFORMATION PROCESSING SYSTEM (FIPS).

	SHORT NAME: CNTY_CD
	LONG NAME: BENE_COUNTY_CD

	EDIT-RULES:
	NUMERIC

	LIMITATIONS:
	SOME CODES MAY BE INVALID, UNKNOWN, OR '999'.
	(DIFFERENT FROM FIPS)

	CCW FIELD SOURCE AND DERIVATION:
 	  RIC-O; Field Name: BENE_MLG_CNTCT_CNTY_CD
 	  The residence change date is determined as described 
	  under state_cd.

	  If the state_cd='05' and the cnty_cd='407', 
	  the cnty_cd = '470'.

	  If there is no residence record, the cnty_cd='999'

	  If the state_cd='99' and the cnty_cd is not equal to '000', 
	  the cnty_cd='999'

	CMS DENOMINATOR DIFFERENCE:
	  The SSA county code of residence of a beneficiary is obtained 
	  in the same manner as the beneficiary's state code described above.  

	  If the state_cd='05' and the cnty_cd = '210', the cnty_cd = '200'.

	  If there were no Residence records (RIC-O) found for a beneficiary 
	  on the EDB, or if the county code for the residence is unknown, 
	  then the beneficiary's SSA county code is set to '999'.
