STATE CONTRIBUTION.

(a) For each plan enrollee, from the state contribution that would otherwise be made for basic coverage for the enrollee, the state shall contribute annually to a high deductible health plan under this subchapter the amount that is necessary to pay the cost of coverage under the high deductible health plan and does not exceed the amount the state annually contributes for a full-time or part-time employee, as applicable, who is covered by the basic coverage.

(b) For each plan enrollee's dependent covered under this subchapter, from the state contribution that would otherwise be made for basic coverage for the dependent, the state shall contribute annually to the high deductible health plan under this subchapter the same percentage of the cost of coverage under the high deductible health plan as the state annually contributes for dependent coverage in the basic coverage.

(c) Before each plan year, the board of trustees may determine the amount of allocation of the state's contribution, if any, to an enrollee's health savings account that would otherwise be made for basic coverage for the enrollee and that remains after payment for coverage under Subsection (a) or (b).

(d) For a calendar year, the amount of any allocations made under Subsection (c) and Section 1551.455(c)(2), in the aggregate, may not exceed the sum of the monthly limitations imposed by federal law for health savings accounts.
