Each insurance company has its own set of requirements. Consider yourself extremely lucky! Your new insurance is great. Since I am disabled, I am on Medicare. Medicare's requirements for medical necessity include: (1) BMI > 35, (2) an associated co-morbidity like diabetes, sleep apnea, hypertension, (3) and a documented history of failed attempts at medical weight management. Yet, Medicare does not specify how many attempts and over what time period. It turned out that I could use documentation from 3 years ago.
Also, each insurance company operates at its own pace. I heard back lightning quick. I applied on Dec. 27th, approved electronically, and was told by my provider today. We even scheduled today.
