11/20/2025	4.0.22	EL-3-009-5	UPDATE	Specification	STEP 1: Enrolled on the last day of DQ report monthDefine 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 missing3. MSIS-IDENTIFICATION-NUM is not missingSTEP 2: Eligibility determinants on the last day of DQ report monthUsing 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 = 12a. ELIGIBILITY-DETERMINANT-EFF-DATE <= last day of the DQ report month 3a. ELIGIBILITY-DETERMINANT-END-DATE >= last day of the DQ report month OR missingOR2b. ELIGIBILITY-DETERMINANT-EFF-DATE is missing3b. ELIGIBILITY-DETERMINANT-END-DATE is missingSTEP 3: Unique foster care enrolleesOf the MSIS IDs that meet the criteria from STEP 2, select foster care enrollees:1. ELIGIBILITY-GROUP = "08" or "09" or "30"2. Remove any duplicates, so each MSIS-ID only appears once.STEP 4: Primary demographics on the last day of DQ report monthUsing the MSIS IDs that meet the criteria from STEP 3, join to segment PRIMARY-DEMOGRAPHICS-ELG00002 by keeping records that satisfy the following criteria:1a. PRIMARY-DEMOGRAPHIC-ELEMENT-EFF-DATE <= last day of the DQ report month 2a. PRIMARY-DEMOGRAPHIC-ELEMENT-END-DATE >= last day of the DQ report month OR missingOR1b. PRIMARY-DEMOGRAPHIC-ELEMENT-EFF-DATE is missing2b. PRIMARY-DEMOGRAPHIC-ELEMENT-END-DATE is missingSTEP 5: Calculate ageOf the MSIS IDs that meet the criteria from STEP 4, calculate age:1a. If DATE-OF-DEATH is non-missing and occurs before the last day of the DQ report month, Age is equal to the years between DATE-OF-DEATH and DATE-OF-BIRTH.1b. Otherwise, Age is equal to the years between the last day of the DQ report month and DATE-OF-BIRTH. Note: perform calculations to count full years (e.g., 5/1/2015 – 8/1/1950 = 64)STEP 6: Foster care enrollees aged < 26Merge the MSIS IDs from STEP 3 and 5 and only keep the matches and make sure there is still only one observation per MSIS-ID. Then, select foster care enrollees with Age < 26.STEP 7: Calculate percentage for measureDivide the count of MSIS IDs from STEP 6 by the count of MSIS IDs from STEP 3	N/A
