Don't give up my insurance denied me three times. Hey I have nothing but my whole life to wait so every time they denied me I wrote an appeal letter to the insurance. Well they gave up the fight and approved me. You have to explain to then how getting this done will benefit your health and MOST important insurances want to save money. Explain to them how getting the done will save then cost in diabetes care etc I have sleep apnea so I told them at my age, they are looking at more in Cpap machines pulmonary care and sleep test. Well that adds up over the years so they looked at the obligation picture. They just need you to map or outline it out for then that way when you appeal it will go before a panel of usually nurses that can see past the first line. Try it. It sure help me
