Insurance giant State Farm has filed a federal lawsuit against a Tampa chiropractor and his doctor-lawyer referral service.

State Farm has alleged a fraud scheme against chiropractor Gary Kompothecras and his 1-800-ASK-GARY referral service.

The insurance company is suing over $19 million in no-fault medical claims they say they paid out to the physicians group and clinics that Kompothecras founded.

The lawsuit says those claims were part of a "massive fraud scheme" and that the insurance group was not responsible for covering all of those claims.

State Farm officials say they've identified at least $480,000 in such illegal claims. The 52-page complaint, filed Friday, also seeks punitive damages.
