1. What is Medical Loss Ratio?

Medical Loss Ratio (MLR) is a key metric used in the health insurance industry under the Affordable Care Act (ACA) that measures the percentage of premium dollars spent on medical care and quality improvement activities versus administrative costs and profits.

2. How Does the Calculator Work?

The calculator uses the ACA MLR formula:

Where:

• \( Medical\ Costs \) — Total medical expenses paid for enrollees
• \( Quality \) — Expenses for activities that improve health care quality
• \( Premiums \) — Total premium revenue collected

Explanation: The MLR represents the proportion of premium dollars spent on patient care and quality improvement versus administrative expenses and profits.

3. Importance of MLR Calculation

Details: The ACA requires health insurers to maintain minimum MLR standards (80% for individual/small group, 85% for large group). Insurers failing to meet these standards must provide rebates to consumers.

4. Using the Calculator

Tips: Enter all amounts in the same currency unit. Medical costs and quality expenses must be non-negative, while premiums must be greater than zero for valid calculation.

5. Frequently Asked Questions (FAQ)

Q1: What are the ACA MLR requirements?
A: Health insurers must spend at least 80% of premium dollars on medical care and quality improvement for individual and small group markets, and 85% for large group markets.

Q4: How is MLR reported and enforced?
A: Insurers must report MLR data annually to state and federal regulators, who monitor compliance and ensure rebates are paid when required.

Q5: Are there any exemptions to MLR requirements?
A: Some states may receive adjustments for individual market instability, and very small insurers may have different reporting requirements.
