NCQA will remove the RAND table from the Guidelines for Calculations and Sampling with the release of the HEDIS MY 2025 Technical Update on March 31, 2025. Future releases of the HEDIS Volume 2: Technical Specifications for Health Plans publication will not contain a RAND table.
Beginning MY 2025, NCQA will use an alternative timeline and approach to distribute RAND numbers for HEDIS reporting. This information will be released in the NCQA store for purchasers of HEDIS Volume 2 in the November before production of systematic samples for hybrid reporting (e.g., November 2025, for MY 2025).
Organizations participating in NCQA’s Measure Certification program will receive separate guidance on how NCQA will accommodate this change for certification of systematic sampling logic.
