The Mississippi Division of Medicaid (DOM)’s Office of Third Party Recovery is charged with the task of identifying and recovering funds by means of collections from third persons by either assignment or subrogation. DOM has contracted with Health Management Systems (HMS) to act as its collection vendor to facilitate and enforce the agency’s statutory right to recovery. HMS manages all case and lien valuations for DOM’s fee-for-service casualty cases.

Pursuant to federal and state law, DOM must seek the recovery of funds spent on any Mississippi Medicaid beneficiary’s medical care whenever there is a responsible third party.  Mississippi law creates an automatic right of recovery and outlines the distribution method for any funds recovered in a personal injury or casualty case. See Miss. Code Ann. § 43-13-125.
