Depending on what you are trying to get - insurance for a 1/2 unit pen versus a whole unit pen should not be a very hard thing to get. I think the pens cost about the same, so it should not matter to the insurance company, the cost is roughly the same. This should not be a difficult one to win.
If you need a 1/2 unit pen, you need to specify that you need more granularity in your dosing. State that whole units do not give you enough adjustability, and 1/2 unit dosing provides more scalablity and precision. State that you are unable to fine-tune your dosing with whole units. Not being able to scale in 1/2 units increases your risk of both hypoglycemia and hyperglycemia, and increases the risk of complications.
So for 1/2 unit pens, lets say the “magic words” are:
- increased risk of complications
A few more points. The NovoLog Echo pen (NovoPen Echo, is I think what they call it) has the memory function as well as the 1/2 unit dosing. The memory lets you know the time of the last dose, which can help you calculate your IOB, etc. So I think that would be a good thing to mention.
Furthermore, the Echo pen has replaceable cartridges, so the cost might actually be very comparable.
Here is a quick guide:
