This bit Fred, "still investigational and not medical necessary"...

This bit Fred, "still investigational and not medical necessary" this means no silent coverage or approved for use for this policy.
Probably will get reviewed again in May 2025.
It's not about been in guidelines, it's about the advisory committee understanding the science and the benefit to the insurer.





This can also be outsourced to research providers who provide a recommendation using their expert knowledge and passing that onto the committee.

Here is a link to Hayes, I think they advise Humana on policy.

Below is Hayes reasoning for providing investigational & not medical
"Controversy: The electronic devices used to measure BIA are fairly complex and they may not be any more accurate than simple techniques such as water displacement volumetry or arm circumference assessment with a tape measure.":

We know the SOZO is superior in detecting subliminal BCRL, they need time to catch up.
I expect IPD would be targeting their policy change resources depending on priority to get policy change.
