Association Between a Capitated, Low-cost, County-Based Public Health Insurance Option and Affordable Care Act Premium Growth in California.

ABSTRACT:

Importance

Empirical evidence is needed on how a capitated, risk-based county plan performs as a viable public option in the Affordable Care Act (ACA) Marketplace in California.

Objective

To estimate whether LA Care-a capitated, county-based public option and California's largest public insurer-was associated with health insurance premium growth in the Los Angeles (LA) regions of Covered California (CC), the ACA exchange in California.

Design, setting, and participants

This economic evaluation used ACA silver plan premium data within the 19 CC regions. Difference-in-differences and event study models used data on plan-level premiums from Health Insurance Exchange Compare for years 2014 to 2022 to estimate the association between LA Care and ACA premium growth in LA.
