If you’re a patient and need his help, he would probably let you die unless you hand him the payment first. A low-life, unethical, so-not-professional«specialist» who doesn’t know how the American health care works! I got a doctor referral to see a specialist for my carpal tunnel symptoms. I made double sure to call my insurance company to verify this Qun Xu MD is within the network and that my claim will be covered. I went to this doctor when everything was verified and good to go. Arrived at the place at 4pm, the front desk lady Emily saw my insurance card and told me she never heard of the network. I told her to call my PCP and call Healthnet but she only called my PCP. My PCP confirmed the coverage and eligibility. The Qun Xu «doctor» still refused to accept that fact and asked me to pay $ 125 up front! I told Emily to call the insurance directly if they were so worried of the eligibility but she refused and told me to use my personal mobile to cal(how rude), which I eventually did. I let the insurance rep to talk to Emily directly and confirmed that my claim will be paid. Still the moron doctor kept insisting me to pay $ 125 up front! What the!!! No treatment was given to me after one hour of struggle at this moron’s office. Since I still have the insurance rep on the phone I told her to fax all the eligibility documents right away to the moron doctor. She did and still the low-life moron, heartless doctor refused to see me unless I pay $ 125!
