A large health insurer is introducing mini medical plans aimed at employers in Colorado and New Mexico.

UnitedHealthcare, a unit of UnitedHealth Group Inc., Minnetonka, Minn., says its new UnitedHealth Basics plans will offer access to the parent company’s heavily discounted provider network.

Plan members also will get access to a 24-hour nurseline, UnitedHealthcare says.

Typical mini medical plan premiums will be 60% to 75% lower than premiums for traditional, fully insured health coverage, and employers must pay 25% to 50% of the cost, the company says.
