Charged for Dr. looking at cgm data

I got a 350.00$ charge for the doc to look at my CGM data. Not sure if they looked at it more in depth later but when I shared the dexom code she checked it out for about 3 minutes during the 10 minute apt. - this was charged to my insurance as a Lab Diagnostic, CGM eval. on the summary I get from the insurance company.

Never seen this before, is this a new tactic to get more from insurance/me in terms of reimbursement? Seems a little over the top IMO.
