MSIS-IDENTIFICATION-NUM is situational in the FTX00003 segment because some of the covered lives on a commercial individual market health insurance policy may not be eligible for Medicaid or CHIP, although at least one member of the policy must be eligible for Medicaid or CHIP.
There should be one FTX00003 segment for each person covered under the commercial individual market policy for which the premium assistance payment is being paid, regardless of whether that particular person is eligible for and enrolled in Medicaid or CHIP. |
