# 484.370 Process for determining and applying the value-based payment adjustment under the Expanded Home Health Value-Based Purchasing (HHVBP) Model.
(a) *General.* Competing home health agencies are ranked within the larger-volume and smaller-volume cohorts nationwide based on the performance standards in this part that apply to the expanded HHVBP Model, and CMS makes value-based payment adjustments to the competing HHAs as specified in this section.
(b) *Calculation of the value-based payment adjustment amount.* The value-based payment adjustment amount is calculated by multiplying the home health prospective payment final claim payment amount as calculated in accordance with § 484.205 by the payment adjustment percentage.
(c) *Calculation of the payment adjustment percentage.* The payment adjustment percentage is calculated as the product of all of the following:
(1) The applicable percent as defined in § 484.345.
(2) The competing HHA's Total Performance Score divided by 100.
(3) The linear exchange function slope.
