Circle Medical billing me for exams that never happened?

I was a patient of Circle Medical (app based virtual visits) for about 8 months and loved how easy it was. I see an LPN once a month for about 6 minutes to discuss symptoms/treatment and renew my prescription.The charges were consistent, but my most recent visit was double what it normally costs and weird charges had been added (no insurance changes) . There was a $200 charge for “after hours visit” when all my appointments had been around 11am. They also listed things like “checked range of motion in shoulders and knees” despite this woman only seeing my face. My bills always said I saw an MD by a completely different name and they would bill for 3 hours of her time when my appointments were always under 10 minutes. Conveniently the time they needed to “consult with my insurance company” was just long enough that I can no longer dispute the (autopay) charge with my bank. I plan to call my insurance company, I’m just not sure if the full costs of the visit would fall on me if they decide the charges by Circle are incorrect/fraudulent? Very inexperienced in the health insurance field and anywhere I can report this or even what to call it would be appreciated.
