Only to have my tonsils already cut 6/7 appointments, now it appears that ZH not contracted with my health insurance company I already have to pay 300 in addition to my deductible. There will still be a big bill. Have not received any notification from the ZH that they are not contracted with my health insurance company. Isn't it difficult to give a report?
