Annotation

Calculate the percentage of eligibles with SSN and MSIS ID

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: Variable demographics on the last day of DQ report month

Using the MSIS IDs that meet the criteria from STEP 1, join to segment VARIABLE-DEMOGRAPHICS-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 3: Non-missing SSN

Of the MSIS IDs that meet the criteria from STEP 2, further refine the population by keeping records with non-missing SSN

STEP 4: Non-missing MSIS ID

Of the MSIS IDs that meet the criteria from STEP 3, further refine the population by keeping records with non-missing MSIS-IDENTIFICATION-NUM

STEP 5: Calculate percentage for measure

DIVIDE the count of MSIS IDs from STEP 4 by the count of MSIS IDs from STEP 1
