Masking Algorithm Version Code

1) If M0150 CPAY MCARE FFS = 0 and M0150 CPAY MCARE HMO = 0 and M0150 CPAY MCAID FFS = 0 and M0150 CPAY MCAID HMO = 0, then the patient's care is not paid by Medicare or Medicaid and MASK VERSION CD must be completed. The only valid value for MASK VERSION CD is 'FIPS SHA-1 V1.00' (left justified, blank filled). 2) If M0150 CPAY MCARE FFS = 1 or M0150 CPAY MCARE HMO = 1, or M0150 CPAY MCAID FFS = 1 or M0150 CPAY MCAID HMO = 1 then the patient's care is paid by Medicare or Medicaid and MASK VERSION CD must be blank. 3) If MASK VERSION CD is not blank, then the following non-blank fields must be masked: M0020 PAT ID, M0040 PAT FNAME, M0040 PAT LNAME, M0063 MEDICARE NUM, M0064 SSN, and M0065 MEDICAID NUM. If any of these fields is blank, then do not mask the field -- submit blanks for that field instead. Do not mask an entirely blank field. 4) If MASK VERSION CD is blank, then no filed in the record is to be masked.
