H.B. No. 1819 aims to amend the Government Code to establish a grant program that supports community mental health initiatives for veterans and their families. The bill modifies the matching grant conditions for single and multiple counties, specifically changing the required non-state funding contributions for community mental health programs. For counties with populations of 250,000 or more, the required matching funds will now be 75 percent of the grant amount, a reduction from the previous requirement of 100 percent. This adjustment applies to both single-county and multi-county programs.

The bill stipulates that the changes will only apply to grants awarded on or after the effective date of September 1, 2025, and grants awarded prior will continue to follow the existing law. Additionally, the implementation of these changes by the Health and Human Services Commission is contingent upon the legislature appropriating sufficient funds specifically for this purpose. If such funding is not provided, the commission may choose to implement the changes using other available resources.
