If the telemedicine app can geolocate your IP address it can independently determine what state you are in.
Sure, if something looks fishy you could then go through the appropriate legal channels to get a more exact location from the ISP, but false positives are going to happen so often, eventually everyone involved might get a bit cranky.
* Only the likes of Google have the scale and requisite information to keep more accurate and up-to-date databases, and even those are fallible.
You can't trust even that. There's an ISP which shares the IP pool between its child companies (? or some similar arrangement) in Crimea and Poland. We found out when Polish subscribers got affected by sanctions on business with Crimea.
Don't trust it for anything important ever.
