Benchmarking Comparison and Performance Analysis (B-CAPA) Reports

NAACOS is pleased to provide complimentary B-CAPA Reports for members. The B-CAPA reports feature individual ACO performance relative to various aggregate “peer groups” for areas such as demographics, per beneficiary expenditures, and utilization. The reports are available for both Medicare Shared Savings Program (MSSP) and Next Generation ACOs (BCAPA-NG). Below is more information on the BCAPA reports, available supporting materials, and instructions on how to access the reports.

In Spring 2019, NAACOS released the newest B-CAPA Report, version 1.5, for MSSP members. The B-CAPA 1.5 Report compares data in the 2016 performance year and includes several changes from previous reports, including:

  • New Data Source: B-CAPA 1.5 uses 2016 data from the extensive NAACOS claim database which allows for more granular analysis.
  • New Measures: B-CAPA 1.5 includes the Berenson-Eggers Type of Service (BETOS) clinical categories for Part B expenditures along with institutional spending. This includes information on evaluation and management, tests, imaging, procedures, durable medical equipment, other and exception services rendered by clinicians or other Part B providers. More on the BETOS categories and codes can be found here
  • New Sub-groups: B-CAPA 1.5 includes break outs of all measures for beneficiaries who are Disabled, Aged Dual, Aged-Non-Dual or those with end-stage renal disease (ESRD). 

Other important features include:

  • Timing: The last B-CAPA report was based on 2017 Public Use Files (PUF) which contain aggregated data and do not permit detailed analysis.  We are switching to detailed Medicare claims data to provide more information and producing the first report with 2016 claims data.
  • Comparison group: right now, the reports include a regional comparison group made up of ACOs in your region.

New B-CAPA report for Next Gen ACOs

  • Data for Performance Year 2018
  • Multiple peer groups for comparison including ACOs with similar: CMS Hierarchical Condition Categories (CMS-HCC) risk score, network structure, proportion end-stage renal disease (ESRD) beneficiaries, Per-beneficiary-per-year (PBPY) expenditures, CMS Region, and all other NextGen ACOs.

Enhancements are already underway and feedback from ACOs are encouraged!
