BlueCross BlueShield of Tennessee contributed $10.7 million in charitable giving last year and its employees donated more than 8,000 hours of service to local communities.

The Chattanooga-based health insurer said it gave its biggest contributions last year to a statewide campaign to battle opioid abuse and its support of the new Miller Park in its hometown.

BlueCross, the state's biggest health insurer which helps insure more than 3 million Tennesseans, said the company's annual giving tally included $9 million from the BlueCross BlueShield of Tennessee Health Foundation, $600,000 from the Community Trust and $785,000 in corporate donations.

"We truly are 'of Tennessee,' and we are committed to keeping our neighbors and communities healthy and strong," Roy Vaughn, chief communications officer for BlueCross and executive director of the BlueCross BlueShield of Tennessee Health Foundation, said in a statement today. "In 2017, we provided funding and support to organizations serving people in virtually every corner of the state."

Major charitable investments by BlueCross for 2017 included:

* $1.3 million to the Count It! Lock It! Drop It! statewide campaign to reduce opioid misuse and abuse
