Myofunctional therapy (coded as Speech Therapy) being coded as two treatments despite a single short visit with the same person leading to copay AND coinsurance/deductible. Seems wrong

My son needed myofunctional therapy to go along with oral surgery. When we first spoke with the therapist, they advised it would be $50 per visit from us, which is our specialist copay rate.

Now, roughly eight weeks later, we find out it was only the first visit that was like that. It turns out they are filing it under two different treatment codes leading to elevated out of pocket: $50 copay and a $26 coinsurance cost (basically the total cost of the second treatment after insurance discounts).

First, isn’t the point of copayment to cover the services render from one visit outside of things like imaging or surgery? Why is BCBSTX doing this? I can’t seem to get a clear definition of what a copayment should cover.

Second, is it appropriate for the therapist to file like this? We visit a single person who basically walks through a set of exercises for the tongue. We visit them every week. My son does these exercises three times a day. We have no real documentation of the therapy except a worksheet to track the what he’s doing. And the treatment seems focused on the at home practices during our brief 20 minute visits. They use treatment codes 92526 (swallowing treatment) and 97535 (home therapy training). I saw mention of Medicaid/care not wanting 97000 codes used with 92000 codes.
