What is the BCBS Health Index?

The BCBS Health Index provides a comprehensive measure of health by quantifying how more than 200 health conditions affect the health and well-being of commercially insured Americans. The BCBS Health Index assigns defined populations a health index score between 0 and 1, where 1 represents optimal health and anything less than 1 represents the adverse impact of illness or disease on longevity and quality of life.
