Volunteer Protection Act of 1993 - Prescribes circumstances under which volunteers working for nonprofit organizations or government entities shall be immune from personal financial liability for acts on behalf of the organization or entity. Sets forth exceptions and conditions that a State may impose on the granting of such immunity. Requires the Secretary of Health and Human Services to increase by one percent the fiscal year allotment which would otherwise be made to a State to carry out the Social Services Block Grant Program under title XX of the Social Security Act if such State has, within two years, certified to the Secretary that it has enacted a State law which provides such immunity. Provides for the continuation of such increase based on an annual recertification.
