When we talk about health insurance, it’s usually in the context of a complaint. While it’s true that insurance companies often fight tooth and nail to keep their financial exposure limited, they’re also making moves to offer benefits beyond standard health care—and you might not even know about these perks.

A prime example is the recent trend for companies to offer a discount savings card on groceries. United Healthcare, Humana, and Medica are just a few of the insurers who have issued cards that can be used for an instant price reduction when checking out at participating stores. The catch? The programs typically cover healthy or organic foods. Along with discounted gym memberships, the benefit is an effort to keep policy holders fit and—at least theoretically—to reduce the need for medical interventions.

If you’re surprised to hear about it, you’re not alone. Here are some other programs offered by the nation's largest insurance companies that you might be missing out on. (Bear in mind that each company has various tiers of coverage and not all perks may apply to all levels.)

UNITED HEALTHCARE

The company’s Healthy Savings program for groceries allows shoppers to save on select items that change on a weekly basis. Each Sunday, the cards will recognize between $40 and $50 in deals on healthier grocery options. It’s only good at participating retailers, including Shop ‘n’ Save, Giant, and others. You can search for locations on their website.

Through UnitedHealth Allies, the company also offers discounts on weight loss programs like NutriSystem and Jenny Craig, as well as gym memberships and even active footwear [PDF].

CIGNA

The Northeast-based insurance company provides an umbrella discount service, Healthy Rewards, that offers savings on eye exams and up to 25 percent off alternative health therapies like acupuncture, chiropractic, and massage appointments [PDF]. They also offer fitness membership discounts. More information can be found at MyCigna.com.

AETNA

It’s hard to know what the pending acquisition of Aetna by pharmacy giant CVS will mean for health care perks moving forward. Currently, the company offers discounted memberships and trial passes to more than 10,000 gyms nationally, as well as discounts on home fitness equipment like treadmills [PDF]. You can also find discounts on meal home delivery subscriptions. Logged-in members can go to the Aetna website and select “Health Programs” then “Discounts” to determine your eligibility.

ANTHEM BLUECROSS

In addition to savings on groceries, gym memberships, and weight loss programs, Anthem BlueCross offers savings for members on DNA ancestry kits, pet insurance, and even baby-proofing.

HUMANA

Humana offers an impressive array of “lifestyle discounts” that range from basic wellness perks to teeth whitening, identity theft services, and 15 percent off in-network LASIK procedures. They also offer discounts on over-the-counter medications like Claritin and Advil. You can register at MyHumana.com to find out more.
