Re: My takeaway from this..
Just guessing, but my first thought was that it's not so much "riding a hoverboard" as "filming and sharing the video" that's the real crime here.
Looking at the complaint, it seems that the actual crime was "unnecessarily sedating the patient and billing Medicaid for it". Trust Alaska to reduce the whole thing to "unlawful billing". Presumably if you want to play silly buggers with a patient in this way, sedation becomes... more desirable.
