According to Insuranceopedia…
“Ancillary benefits are additions to a health insurance plan provided by an employer to his or her employees. These additions to the health plan are often the following: vision care, dental care, and life insurance. The employer can subsidize this plan and might ask the employees to contribute to it. These benefits are then added to already existing group health insurance.”
“Don’t forget short-term and long-term disability!”
Ancillary benefits typically add onto a major medical offering to round out and increase employee protection options.
