2230.0404.08 - Stepparents in Home (MFAM)
When there are two legally married stepparents in the home and neither is an SSI, OSS, or ICP recipient and each has children who are eligible for 1931 Medicaid (nonmutual children), two standard filing units (SFU’s) must be set up.
If there is a mutual child and one or both parents are incapacitated or one parent is an unemployed principal earner or an SSI, OSS, or ICP recipient, one SFU must be set up. The children’s needs and the needs of the incapacitated or PE parent(s) must be included in the SFU.
When a parent and a stepparent are in the home, the parent's needs are included in the assistance group with the child. Stepparents who have no eligible children of their own may not be included in the AG under any circumstance.
