Update: Insurance company covering office visit under surgical benefits

Earlier this year I went to an ENT and had an unplanned endoscopy. My insurance processed the office visit portion of the bill to my surgical benefits (coinsurance/ded) instead of office visit benefits ($75 copay).

Can anyone help me understand why this office visit is billed as coinsurance and not a copay? My specialist benefits say "$75 copay, deductible does not apply."

I spoke with 4 different provider services reps with my doctor’s office most who understood the issue but couldn’t help.

My state’s insurance commissioner was of absolutely zero help, they told me that they reviewed the insurance company’s internal policy and that everything was processed correctly. I’m still kind of pissed about this.

The health system told me that I was out of options beyond being granted financial assistance, or making a claim in court. Then out of the blue I got a new (4th time reprocessed) EOB stating that everything would be covered (including the diagnostic procedure CPT) under my $75 office visit copay.
