Key Takeaways
- MLR is the medical loss ratio. ACA rules require individual and small group insurers to spend at least 80 percent of premium dollars on medical claims and quality improvement, or issue rebates to policyholders.
- Large group plans face an 85 percent MLR threshold. When issuers miss the target, they mail rebate checks or premium credits to employers and individuals. Rebates are taxable in some situations depending on how the client paid premiums.
- MLR does not mean a specific plan is high quality. It is a financial reporting rule about premium use, not network breadth or customer service.
- Brokers occasionally field MLR rebate questions in late summer when CMS publishes rebate data. The answer is plan and year specific, not a universal client refund.

FAQ
Common broker questions about this term.
Do MLR rebates go to brokers?
No. Rebates go to policyholders or employers. Brokers may help clients understand the notice but do not receive MLR payments.
Does a low premium plan mean better MLR?
Not necessarily. MLR compares claims paid to premiums collected across the issuer's block, not a single plan's value for one client.
Should brokers recommend plans based on MLR?
MLR is a regulatory accounting metric. Plan fit should still be driven by network, drugs, total cost, and client utilization.
