Louisiana’s health insurance market for individuals has been plagued in recent years by insurers fleeing the market and double-digit rate increases — prompting a proposed fix that would tack a fee on policies across the state to create a safety net against insurers’ losses and hold the line on runaway premiums.

The state Department of Insurance is pushing a bill through the Legislature that it says would lower premiums in the individual market by an average of 15 percent next year. The bill would put a roughly $1.25-a-month fee on every health-insured life in the state. That money, which one critic labeled a tax on business disguised as a fee, would go into what is called a reinsurance pool designed to protect insurers against high-cost patients.
