Hi Fisher,
Sorry to hear about your setback. Definitely file for an appeal, it doesn't hurt.
As for the co-morbidity issue... I noted that your BMI is under 40. Depending on your insurance, a co-morbidity may be a requirement if you don't meet the minimum BMI (my insurance was 40). Some co-morbidities like sleep Apnea, Diabetes, heart disease etc are imminent diseases that are life threatening. Additionally, these diseases cost insurance companies far more in the long run than the LB procedure. However, other co-morbidities such as elevated blood pressure and cholesterol is questionable and not always obesity related. First, how elevated are your labs and are there any sign of disease from these elevated levels. Have you been previously diagnosed and treated for these conditions, has your treatment been successful in managing these levels. If there is not a extremely high level, the insurance company may disregard it and not associate the obesity as having any negative impact on your body (yet).
Garbage, I know. But it's the game we all play
