# §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](/cfr/42/484.205.md) 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](/cfr/42/484.345.md).
  - (2) **The competing HHA's Total Performance Score divided by 100.**
  - (3) **The linear exchange function slope.**
