Medicaid needs a letter of representation from the attorney. The claim adjuster may send a written request. Requestors must also send a HIPAA Authorization signed by the recipient, parent, or legal guardian if a minor, permitting the release of information. These statements may be faxed or mailed to the Department of Health Care Finance, Third Party Liability Section, Suite 1000S, 441 4th Street, NW, Washington, DC 20001, fax (202) 727-5645.
