Kasey's neck surgery

We are in need of help to fund a disk replacement surgery in Kasey's neck. We have been fighting the insurance for the past 4+ months but they have denied it claiming that it is an experiential procedure. Kasey has been fighting neck and back pain for many years and it finally became too much for him to take. After going to the back surgeon an MRI was done and he has 4 bulged discs in his neck alone amongst other issues. For him to be able to get the replacement instead of the fusion we will have to finance it ourselves. The discs are  the best option for Kasey because he will get all of his range of motion back and they will not put strain on the other discs in his neck. Plus we will have 10 to 12 years until we will have to fix the other two discs. The fusion will limit his motion, put strain on the upper and lower discs and will maybe give us 5 years until we have to fix the other two discs . Kasey is only 32 years old. We don't want him to have to do surgery after surgery just for him to have to retire early and have to live on pain meds just to function. We are also already in medical debt from an emergency surgery. Kasey was hospitalized earlier this year for an infection is his leg that spread into his blood that required surgery. Kasey is a loving  husband and father. We are fighting for the best life we can get. So that we can enjoy our kids and somday grandkids.  At this point we are asking for any help that you are able to give. Thank you.
