If i go to a doctor because of lumpy painful wrist syndrome and I think it's carpal bossing but idk, but also I injured my wrist like an idiot 7 years ago when i was uninsured, do I need to play dumb about that injury or else insurance will deny me or something because it's pre-existing and then i'll have to pay a million dollars to have a working hand? My natural inclination is to not lie about shit and it's relevant but also i don't have a million dollars if being like "so yeah i think i fucked up my wrist half a decade ago" is gonna fuck me on insurance?
I don't think you need to lie to her doctor about your wrist injury. Usually, doctors are slightly more on your side than insurances and will work with you to find something a treatment that is covered.
That's a shame. I don't know enough about the American healthcare industry to give you any good advice but in lieu of someone coming along with that I'd play dumb and deny that anything happened and say that you started noticing problems during the period of coverage.
