Key Differences in Medical Malpractice Insurance

Program Fit

CNA’s brochure names outpatient classes including ambulatory surgery, dialysis, clinics, and home health. Liberty Mutual describes different healthcare professional-liability solutions for hospitals, outpatient providers, and physician groups. Match the exact operating entity and clinical service to a program; neither broad category alone tells you which professions or subsidiaries a specific quote accepts. 4 7

Layering and Policy Terms

CNA describes primary liability options plus separate excess or umbrella towers. Liberty Mutual’s named hospital, outpatient, and physician-group programs call for a class-specific quote. Ask it for the issuing company, policy form, limits, and exclusions; ask CNA to itemize its primary and excess layers for the same covered entities. 4 7

What to Confirm in Medical Malpractice Insurance Quotes

  • Ask Liberty Mutual which named program applies and request limits, deductibles, and policy form. 7
  • Ask CNA to itemize primary and excess limits and list covered professions. 4
