Code of Federal Regulations Title 42. Public Health § 42.412.154 Payment adjustments under the Hospital Readmissions Reduction Program

(1) General. To account for excess readmissions, except as provided for in paragraph (d) of this section, an applicable hospital's base operating DRG payment amount is adjusted for each discharge occurring during the fiscal year. The payment adjustment for each discharge is determined by subtracting the product of the base operating DRG payment amount (as defined in § 412.152) for such discharge by the hospital's readmission payment adjustment factor for the fiscal year (determined under paragraph (c) of this section) from the base operating DRG payment amount for such discharge.

(2) Special treatment for sole community hospitals. In the case of a sole community hospital that receives payments under § 412.92(d) based on the hospital-specific rate, the difference between the hospital-specific rate payment and the Federal rate payment determined under subpart D of this part is not affected by this payment adjustment.

(1) Ratio. The ratio is equal to 1 minus the ratio of the aggregate payments for excess readmissions as defined in § 412.152 and the aggregate payments for all discharges as defined in § 412.152.

(2) Floor adjustment factor. The floor adjustment factor is:

(1) The determination of base operating DRG payment amounts.

(2) The methodology for determining the adjustment factor under paragraph (c) of this section, including the excess readmissions ratio, aggregate payments for excess readmissions, and aggregate payments for all discharges.

(3) The applicable period.

(4) The neutrality modifier.

(5) The proportion of dual-eligibles.

(6) The applicable conditions.

(1) To ensure that an applicable hospital has the opportunity to review and submit corrections for its excess readmission ratios for the applicable conditions for a fiscal year that are used to determine its readmissions payment adjustment factor under paragraph (c) of this section, CMS will provide each applicable hospital with confidential hospital-specific reports and discharge level information used in the calculation of its excess readmission ratios.

(2) Applicable hospitals will have a period of 30 days after receipt of the information provided in paragraph (f)(1) of this section to review and submit corrections for the excess readmission ratios for each applicable condition that are used to calculate the readmissions payment adjustment factor under paragraph (c) of this section for the fiscal year.

(3) The administrative claims data used to calculate an applicable hospital's excess readmission ratios for the applicable conditions for a fiscal year are not subject to review and correction under paragraph (f)(1) of this section.

(4) CMS will post the excess readmission ratios for the applicable conditions for a fiscal year for each applicable hospital on the Hospital Compare Web site.

(4) CMS posts the excess readmission ratios for the applicable conditions for a fiscal year for each applicable hospital on the Hospital Compare website or successor website(s).
