Key Measures

MIPS impacts the payment adjustment applied to the physician fee schedule. The ACO gets one overall MIPS score. This score translates to a payment adjustment that will be applied to claims, two years after the reporting year (e.g., 2024 program year, submitted in 2025, impacts 2026 payments.) Practices that participate in the ACO's MSSP contract are automatically enrolled in a special MIPS payment model created for ACO participants called the MIPS APM. Because the ACO reports some categories of data on behalf of its participants, this model places a reduced reporting burden on practices, compared to those enrolled in Traditional MIPS. Specifically, the ACO reports Quality data for MIPS and MSSP, Cost is not scored, and MIPS APM participants receive full credit for Improvement Activities.

Promoting Interoperability (PI) - Each ACO participant TIN (tax ID number) is required to report for the Promoting Interoperability (PI) category unless they have an exemption or do not meet the low volume threshold. Providers that do not meet the low volume threshold may be eligible to opt-in and report to receive the ACO’s payment adjustment. Beginning in 2022 the Small Practice exception became an automatic exception (no application required). Definition of small practice is practice or clinician with 15 or fewer clinicians billing under the practice’s TIN. For the 2024 reporting period MIPS reporters must have CEHRT functionality that meets ONC’s certification criteria in 45 CFR 170.315  functionality must be in place by the first day of your MIPS reporting period and functionality must be in place by the last day of the MIPS reporting period. We Will also need to provide your EHR’s CMS identification code from the Certified Health IT Product List (CHPL), available here when you submit your data. We suggest working directly with your HIT / EHR vendor to ensure their compliance plans.

What’s new in 2024:

  1. Updated the CEHRT definition to align with the Office of the National Coordinator for Health IT (ONC)’s regulations 45 CFR 170.315
  2. The only clinician type that now receives automatic exemption is clinician social worker. Discontinued automatic reweighting for physical therapists, occupational therapists, qualified speech-language pathologists, qualified audiologists, clinical psychologists, and registered dietitians or nutrition professionals for the Promoting Interoperability performance.
  3. Increased the performance period to a minimum of 180 continuous days within the calendar year.
  4. Modified the second exclusion for the Query of Prescription Drug Monitoring Program (PDMP) measure beginning with the 2024 performance period so that it reads as follows:
    Any MIPS eligible clinician who does not electronically prescribe any Schedule II opioids or Schedule III or IV drugs during the performance period.
  5. Require a “yes” response for the Safety Assurance Factors for Electronic Health Record (EHR) Resilience (SAFER) Guide measure beginning with the 2024 performance period.
