(1) This rule applies to services provided from January 1, 2008, through November 30, 2008.

(2) Any overall rate change adopted by a hospital shall be reported to the department on a department-approved form before the effective date of the rate change. The department may in its discretion conduct audits of any hospital's financial records to determine proper reporting of rate change filings.

(3) Insurers shall make timely payments of hospital bills. In cases where there is no dispute over liability the insurer shall, within 30 days of receipt of a hospital's charges, either pay the charges according to the rates established by these rules, or notify the hospital that additional information is requested, and specify that information. The insurer shall then pay the charges within 30 days of receipt of the requested information.
