Ala. Code § 27-21B-9: Garnishment of Wages.

(a) The Alabama Medicaid Agency may garnish the wages, salary, or other employment income of any person who is required by a court or administrative order to provide coverage of the costs of health services to a child who is eligible for medical assistance and has received payment from a third party for the cost of services for the child but has not used the payments to reimburse the other parent or guardian of the child, the provider of services, or the Alabama Medicaid Agency for its payments made. Current or past due child support shall have priority over claims for the costs of the services.

(b) In addition to the powers granted in subsection (a), the Alabama Medicaid Agency may notify the State Department of Revenue of any amounts due under this section. Upon proper and timely notice, the department shall withhold any amount from any state tax refund due to the above-described person.
