MEDICAL LOSS RATIO (MLR)

Back to Glossary

Definition

The share of premium dollars spent on claims and quality improvement versus administration and profit; rebates may apply if thresholds aren’t met.


Summary

Medical Loss Ratio (MLR) is a key financial metric in health insurance that measures how much of every premium dollar collected by an insurer is actually spent on healthcare services and quality improvements for patients, versus administrative costs and profits. Think of it as a 'value gauge' - a higher MLR means more of your premium money goes toward actual medical care rather than overhead. Under the Affordable Care Act, insurers must meet minimum MLR thresholds (80% for individual/small group markets, 85% for large group markets) or provide rebates to policyholders.

Usage Context

Critical when studying health insurance regulation, consumer protections under the ACA, insurance company financial performance, and understanding how premium dollars are allocated between patient care and business operations.

Common Confusions

  • Thinking MLR applies to all types of insurance (it's specific to health insurance)
  • Confusing MLR with profit margins or thinking higher MLR means higher profits
  • Not understanding that quality improvement activities count toward the numerator
  • Assuming MLR requirements are the same for all market segments
  • Thinking rebates are penalties rather than consumer protections
