An administrative law judge recommended that the state Agency for Health Care Administration toss aside agreements it signed for treatment of Medicaid beneficiaries with HIV and AIDS in three South Florida counties.

In an 80-page ruling, Judge John Newton said the Agency for Health Care Administration did not follow rules it included in an initial request for vendors in the Medicaid managed-care program. As a result, Newton said the state should reject all responses submitted by managed-care plans for HIV and AIDS treatment in the counties and renew the contracting ­process.
