Kentucky sometimes failed to ensure that all consumers who signed up for insurance on the state’s health exchange were eligible for coverage, the latest federal audit found.

The audit, released Thursday by the inspector general for the Department of Health and Human Services, found that some of the Kentucky exchange’s controls for confirming consumers’ eligibility weren’t effective. Earlier audits also identified deficiencies in the federal exchange, Healthcare.gov, as well as state-run exchanges in California, Connecticut and New York.
