The Texas Health and Human Services Commission contracts with an independent mortality review organization pursuant to Texas Government Code Chapter 546, Subchapter O. A state supported living center (SSLC) must report the death of a person with an intellectual or developmental disability who, at the time of the person's death or at any time during the 24-hour period before the person's death, resided in or received services from the SSLC. The death must be reported to the independent mortality review organization within 72 hours after the pronouncement of death.
