I have been an insulin pump user for quite a few years. With this last pump (about 4-5 yrs. old), I just squeeked past with the c-peptides. My new reading was 1.1. Is this too high to qualify for a pump [for Medicare]? I'm hoping I can make it because I can't survive MDIs ... not enough space for all those bruises!
"CMS has determined that fasting C-peptide levels will only be considered valid when a concurrently obtained fasting glucose is ≤ 225 mg/dL. Insulinopenia is defined as a fasting C-peptide level that is less than or equal to 110 percent of the lower limit of normal of the laboratory’s measurement method. Alternatively, for patients with renal insufficiency and a creatinine clearance (actual or calculated from age, gender, weight and serum creatinine) ≤ 50 ml/minute, insulinopenia is defined as a fasting C-peptide level that is less than or equal to 200 percent of the lower limit of normal of the laboratory’s measurement method. Levels only need to be documented once in the medical records."
So whether or not a 1.1 ng/dl qualifies really depends on you lab reference range. My lab (Quest) has a reference range of 1-3 ng/dl, so 1.1 ng/dl may just barely qualify. That being said, it also says that you only need to document it once in the medical records, so you previous test result may also be accepted. Perhaps others will chime in.
Well, despite all the jargon I don't understand, I am encouraged. It looks like I will squeak through again. I did fast for the test and the 1.1 was a result of the lower BG. It also looks like I just might be "grandfathered" in from my last 2 pump approvals. I am hoping they don't give me a raft of s**t in this process! Thanks.
I guess I am ignorant. I have NO idea what all these tests and numbers mean and/or are used for. I just know that I have been approved for a pump twice in the past for a pump. I just hope that this is good enough for all the bureacrats. It seems that this method has been the best way ever used on me.
Maybe I had better figure a way to get my DR to look at that study somebody sent in this message.
