State High Risk Pool Funding Extension Act of 2005

State High Risk Pool Funding Extension Act of 2005 - (Sec. 2) Amends the Public Health Service Act to reauthorize funds for grants to each state that has not created a qualified high risk pool for the state's cost to create and initially operate such a pool.

Increases the maximum allowable premium charged under a qualified high risk pool to 200% of the premium for applicable standard risk rates. Defines "standard risk rate" as a rate that: (1) is determined under the state high risk pool by considering the premiums charged by other health insurers in the same market; (2) is established using reasonable actuarial techniques; and (3) reflects anticipated claims experience and expenses.

Permits grants awarded by the Secretary of Health and Human Services to states with existing qualified high risk pools to cover operating losses to be made to entities that operate such a pool under applicable state law. Changes the allocation of such grants to give 40% to eligible states equally, 30% based on the number of uninsured individuals in a state relative to all states, and 30% based on the number of enrollees in a state's qualified high risk pool relative to all states. (Currently, all funds are allotted based solely on the number of uninsured individuals in the state.)

Requires a state which charges premiums that exceed 150% of the premium for applicable standard risk to use at least 50% of the grant amount to reduce premiums for enrollees.

Limits the maximum grant amount allotted to territories.

Requires the Secretary to award grants to states with qualified high risk pools for the provision of supplemental consumer benefits, which must include one or more of the following: (1) low-income premium subsidies; (2) a reduction in premium trends, actual premiums, or other cost-sharing requirements; (3) an expansion or broadening of the pool of individuals eligible for coverage; (4) less stringent rules or additional waiver authority with respect to coverage of preexisting conditions; (5) increased benefits; or (6) establishment of disease management programs. Limits to 10% of appropriated funds the amount that any state may be allotted.

Authorizes appropriations for FY2006-FY2010 and appropriates funds for FY 2006.

Sets forth reporting requirements.

Revises the definition of "qualified high risk pool" to allow a state to elect to meet the requirement to provide all eligible individuals with health insurance coverage by utilizing an acceptable alternative mechanism that includes a high risk pool as a component.
