Just in time for fitness resolutions in the new year, UnitedHealthcare announced Tuesday the expansion of a 'wearable wellness' program that offers dollars to subscribers who meet certain walking goals.

Minnetonka-based United, which is the nation's largest health insurer, first partnered last year on the program with technology giant Qualcomm.

Initially offered to certain UnitedHealthcare customers in 12 states, the program now will be available in 40 states, according to an announcement Tuesday at International Consumer Electronics Show 2017 in Las Vegas.

The program has adopted a "bring-your-own-device" model, whereas initial participants were limited to devices offered by the companies. People who use the Fitbit Charge 2, for example, can now participate.

In the 40 states where the program is available, wearable wellness is an option in self-funded employer plans with five or more eligible employees, plus companies with fully-insured health plans with 101 or more eligible workers.

Employees earn up to $4 per day in deductible credits when they meet frequency, intensity and tenacity goals for their walking routines.
