How HCAI Created This Product#

• The source for this data report is the NCDR CathPCI Registry® from 2019 to 2024. The NCDR is an initiative of the American College of Cardiology Foundation®.
• Health Insurance Payment Sources (HIPS) definitions were created by HCAI based on the following Health Insurance Payment Source categories from the NCDR CathPCI Registry® (Full Specifications Data Dictionary v5.0): Private Health Insurance, Medicare, Medicaid, Military Health Care, State-Specific Plan (non-Medicaid), Indian Health Service, and Non-US Insurance. Because the NCDR CathPCI Registry® allows patients to report multiple types of insurance, HCAI created the following HIPS definitions to account for different combinations of insurance that a patient might report (note that Medicaid is referred to as Medi-Cal in California):
  • Commercia Insurance Only: Only Private Insurance as defined in the NCDR CathPCI Registry®
  • Medicare Plus Commercial Insurance: Medicare and Private Insurance as defined in the NCDR CathPCI Registry®
  • Medicare Plus Other Insurance: Medicare and Military Health Care or Non-US Insurance
  • Medi-Cal Plus Other Insurance: Medi-Cal and Private Insurance as defined in the NCDR CathPCI Registry® or Military Health Care or Non-US Insurance
  • Dual Eligible: Medicare and Medi-Cal; or Medicare and State-Specific Plan (Non-Medi-Cal) or Indian Health Service; or Medi-Cal and State-Specific Plan (Non-Medi-Cal) or Indian Health Service
  • All Other Insurance: State-Specific Plan (Non-Medi-Cal) or Military Health Care or Indian Health Service or Non-US Insurance
