CMS has provided an Addendum to this User’s Manual.  The information in the Addendum is effective October 1, 2020 to coincide with the implementation of the MDS 3.0 Item Set, version 1.17.2.   It’s a .zip file so this is what you’ll see when you open it:

The Skilled Nursing Facility Quality Reporting Program Measure Calculations and Reporting User’s Manual Version 3.0 Risk Adjustment Appendix File contains current and historical intercept values, coefficient values, and the risk-adjustment schedule for each risk-adjusted quality measure reported under the SNF QRP. 

The Skilled Nursing Facility Quality Reporting Program Measure Calculations and Reporting User’s Manual Version 3.0.1 Addendum File provides measure-related changes specified in a change table format in lieu of a complete update to the overall manual.  This document is 25-pages of those Change Tables.

The full manual (v3.0) – 106 pages provides the detailed specifications for the SNF QRP assessment and claims-based QRP measures. You will need to adjust what you find in the full manual with the Addendum.
