Tim Hoyt has scary medical bills

This GoFundMe.com story is about my brother Tim Hoyt.  A routine test in 2016 led doctor to suspect prostate cancer.  So the doctors explored with more tests:  CT scans, 3 MRI's, biopsy and numerous blood tests.  The good news is that the biopsy was benign.  The bad news is that Tim was overloaded with a bunch of bills for copays and other things that insurance didn't cover.  Tim and his wife Cathy are on a limited budget, especially after Cathy's recent surgeries and time off work.  I'm asking for your help in getting those obnoxious bills covered.  Please help with what you can.  

Background:  Tim is the son of Milo and Jerrye Hoyt from Fremont California.  He attended Irvington High School in Fremont.  He and his wife Cathy and family now reside in Cheney, Kansas.   Tim is 61 years old.
