Will this hold up in court and what should I do?

I took an ambulance ride after going to the hospital. I had to be transported for 2 hours to another hospital and the bill came out to $3,000. The insurance company sent my wife a check in the mail because she is head of the insurance or was at the time. She cashed the check and blew it all. Now 5 months later I get a letter in the mail for a summons to court for felony theft by fail to make req disp funds because by the ambulance company. I have 4 days to make it 1000 miles because I just got the letter. What should I do?
