Excellus BlueCross BlueShield is looking for owners of "unclaimed funds."

More than 12,000 individuals and companies in New York state have not cashed over $2.6 million in checks issued by Excellus Health Plan.

Every year, the state requires insurers like Excellus BCBS to make a list of unclaimed checks that are at least three years old.

“This is money that was paid for claims or refunded premiums. If the money remains unclaimed it will go to the state,” said Christopher Booth, president and chief executive officer. “It rightfully belongs to our members or providers and we want to make sure they have one more chance to claim it before it goes to the state.”

A list of the names of people and companies with checks to claim can be found on the Excellus website.
