Annotation Calculate the percentage of duals missing a Medicare Beneficiary Identifier
Specification STEP 1: Enrolled on the last day of DQ report month

Define the eligible population from segment ENROLLMENT-TIME-SPAN-ELG00021 by keeping active records that satisfy the following criteria:

1. ENROLLMENT-EFF-DATE <= last day of the DQ report month

2. ENROLLMENT-END-DATE >= last day of the DQ report month OR missing

3. MSIS-IDENTIFICATION-NUM is not missing



STEP 2: Eligibility determinants on the last day of DQ report month

Using the MSIS IDs that meet the criteria from STEP 1, join to segment ELIGIBILITY-DETERMINANTS-ELG00005 by keeping records that satisfy the following criteria:

1. PRIMARY-ELIGIBILITY-GROUP-IND = 1

2a. ELIGIBILITY-DETERMINANT-EFF-DATE <= last day of the DQ report month

3a. ELIGIBILITY-DETERMINANT-END-DATE >= last day of the DQ report month OR missing

OR

2b. ELIGIBILITY-DETERMINANT-EFF-DATE is missing

3b. ELIGIBILITY-DETERMINANT-END-DATE is missing



STEP 3: Dual eligibles

Of the MSIS IDs which meet the criteria from STEP 2, restrict to dual eligibles:

1. DUAL-ELIGIBLE-CODE equals ("01" or "02" or "03" or "04" or "05" or "06" or "08" or "09" or "10")



STEP 4: Variable demographics on the last day of DQ report month

Using the MSIS IDs that meet the criteria from STEP 3, join to segment VARIABLE-DEMOGRAPHIC-ELG00003 by keeping records that satisfy the following criteria:

1a. VARIABLE-DEMOGRAPHIC-ELEMENT-EFF-DATE <= last day of the DQ report month

2a. VARIABLE-DEMOGRAPHIC-ELEMENT-END-DATE >= last day of the DQ report month OR missing

OR

1b. VARIABLE-DEMOGRAPHIC-ELEMENT-EFF-DATE is missing

2b. VARIABLE-DEMOGRAPHIC-ELEMENT-END-DATE is missing



STEP 5: Medicare Beneficiary Identifier is missing

Of the MSIS IDs that meet the criteria from STEP 4, further refine the population by keeping MSIS IDs where:

1. MEDICARE-BENEFICIARY-IDENTIFIER is missing



STEP 6: Calculate percentage

Divide the count of unique MSIS IDs from STEP 5 by the count of unique MSIS IDs from STEP 4
