Medical Loss Ratio
A metric that measures the percentage of premium revenue that health insurance companies spend on medical care and quality improvement activities versus administrative costs and profits. Under the Affordable Care Act, insurers must spend at least 80% (individual/small group) or 85% (large group) of premiums on medical care or provide rebates to policyholders.
Example
“The insurance company's medical loss ratio of 82% meant they spent $82 of every $100 in premiums on actual medical care for their policyholders.”
Memory Tip
MLR = Medical money Lost to Ratio - it measures how much premium money is 'lost' to actual medical care (which is good for consumers).
Why It Matters
Medical loss ratios protect consumers by ensuring insurance companies spend most of their premium income on actual healthcare rather than executive salaries and profits. If your insurer's MLR is too low, you may receive a rebate check, putting money back in your pocket.
Common Misconception
People often think a high medical loss ratio is bad for the insurance company's financial health and will lead to higher premiums. While it does limit profits, the ACA's MLR requirements actually promote efficiency and competitive pricing while ensuring adequate coverage for consumers.
In Practice
Blue Cross collected $100 million in premiums last year but only spent $78 million on medical claims and quality improvements, achieving a 78% MLR. Since this falls below the required 80% threshold for individual plans, they must refund $2 million to policyholders. A customer who paid $4,800 annually would receive approximately a $96 rebate check.
Etymology
The term emerged from insurance regulation terminology, combining 'medical' referring to healthcare costs, 'loss' from insurance parlance meaning claims paid out, and 'ratio' from Latin 'ratio' meaning calculation or proportion.
