A more thorough explanation:

A qualified medical child-support order (QMCSO) is a court order that allows a non-employee custodial parent to enroll their child in the employee parent's group health plan without the employee parent's consent. The employee parent is responsible for paying the expenses related to the child's healthcare coverage.

For example, if a divorced couple has a child and the custodial parent is not employed, they can obtain a QMCSO to enroll the child in the non-custodial parent's group health plan. The non-custodial parent will be responsible for paying the premiums and other healthcare expenses related to the child's coverage.

The QMCSO must meet the requirements established by the Employee Retirement Income Security Act (ERISA) to be considered valid. The group health plan administrator must review and approve the QMCSO before the non-employee custodial parent can enroll the child in the plan.
