The amount of the premium revenues actually spent on paying for medical services.
The ratio between the cost to deliver medical care and the amount of money that was taken in by a plan. Insurance companies often have a medical loss ratio of 96 percent or more: tightly managed HMOs may have medical loss ratios of 75 percent to 85 percent, although the overhead (or administrative cost ratio) is concomitantly higher.
The amount of revenues from health insurance premiums that is spent to pay for the medical services covered by the plan. Usually referred to by a ratio, such as 0.96--which means that 96% of premiums were spent on purchasing medical services. The goal is to keep this ratio below 1.00--preferably in the 0.80 range, since the MCO's or insurance company's profit comes from premiums. Currently, successful HMOs do have MLRs in the 0.70-0.80 range.
Total health benefits divided by total premium.
