§ 412.331 Determining hospital-specific rates in cases of hospital merger, consolidation, or dissolution.
(a) New hospital merger or consolidation. If, after a new hospital accepts its first patient but before the end of its base year, it merges with one or more existing hospitals, and two or more separately located hospital campuses are maintained, the hospital-specific rate and payment determination for the merged entity are determined as follows—
(1) Post-merger base year payment methodology. The new campus is paid based on reasonable costs until the end of its base year. The existing campus remains on its previous payment methodology until the end of the new campus' base year. Effective with the first cost reporting period beginning after the end of the new campus' base year, the intermediary determines a hospital-specific rate applicable to the new campus in accordance with § 412.328, and then determines a revised hospital-specific rate for the merged entity in accordance with paragraph (a)(2) of this section.
(2) Revised hospital-specific rate. Using each hospital's base period data, the intermediary determines a combined average discharge-weighted hospital-specific rate.
