Well first question to my mind is does a CPM actually help? There's a lot of waste in American Healthcare on expensive but fairly useless treatments.
My guess was that a CPM might fall into this category (I did PhD research in bio mechanics in MatSci). So I googled it and it returned a quote:
> Do doctors still use CPM machines? > The machines are no longer widely used because of the multiple studies that found CPM following knee replacement surgery has minimal benefits. However, some surgeons still recommend CPM following knee surgery when the limited pros outweigh the cons in a particular case. (1)
From an insurers perspective it makes sense not to cover a marginally useful piece of equipment. The better use of resources would probably be covering PT where there's movement and weight on the joint.

Fair enough. It was still prescribed by the doctor and I would rather have not paid for it.
Even if its benefits are marginal, they’re probably still more tangible than acupuncture and chiropractic, both of which are apparently covered by my insurance, and the CPM machine probably doesn’t cause a stroke like chiropractic does.
