Some Excellus BlueCross BlueShield customers are receiving refund checks because they were either overcharged or had their claims denied.
A computer glitch last year impacted people on high-deductible plans.
Excellus has been sending out refund checks and will continue to send out more.
They include an additional amount of money – an interest payment for customers.
“We broke it. We own it. We fixed it and we were cleaning it up to make sure everyone who may have been impacted is made whole,” said Excellus spokesman Jim Redmond.
Excellus would not say how many people were receiving checks.
Some people who talked to 13WHAM last year said they were forced to pay their health care bills when the insurance plan should have picked up the costs.
