Vt. Stat. Ann. tit. 33, § 1907

To the extent that payment for covered expenses has been made under the Medicaid program or through any State agency administering health benefits or a health benefit plan for which Medicaid is a source of funding for health care items or services furnished to an individual, in any case where a third party has a legal liability to make payments, the State is considered to have acquired the rights of the individual to payment by any other party for those health care items or services. An insurer shall accept the Agency’s right to recovery and the assignment to the Agency of any right of a person to payment from the third party for medical services for which the Agency has made payment under this chapter.
