Quest Diagnostics Ca [protected]) blood test paid $146.23, quest didn't receive my check and medicare says I don't have to pay the bill.

Four blood tests on 6/29/2021 before my scheduled surgery. The above was denied by Medicare — I appealed. Medicare first said I had to pay. Mailed check to Quest 10/28/2021 to PO Box 3695 Chicago, IL 60693. After that Medicare informed me that Quest didn't process claim correctly, adjustment to be made, I don't have to pay. Mailed letter to Quest 12/29/2021 to find out why my check hasn't been cashed. No Quest agent could give me any positive answers. No record of receiving check and I keep getting phone text messages to pay this bill. Copied Medicare on all of my correspondence. If Quest has my check #7010, I want it returned to me. Still not cashed. Don't want Quest to send this to a collection agency.

Desired outcome: Get my check returned to me and resolve this situation now

Quest Diagnostics Stool sample

I recently did a stool sample & I did what the instructions said & scooped up a parastic worm but my results came back negative. I do not know where to turn in order to get quest held liable for falsly stating there was a neg result. My life can be at risk with parasites in my body! Aside from that they were very rude & would not help me about my doc order about my blood test. It states on their website that quest can call my doc regarding my blood test order... They told me they could not help me & that happened 3 times & still no help from quest employes, highly unprofessional.

Desired outcome: COMPENSTATION FOR FALSLY STATING THAT MY TEST CAME BACK NEGATIVE.....

Quest Diagnostics My drug test has once again came out with a false results.

My drug test has once again came out with a false result. A few years ago it came out positive for Herion, now it just came o but my doctor out positive for PCP. I have never done any of these drugs in my life. This has cost me my reputation and all my doctors have dropped me from my necessary medical treatment.
Maybe my urine sample got mixed up with somebody else's.
i would not mind taking another to straighten this out, but the clinic has dropped me and won't see me anymore.
The clinic is :Inland Psychiatric Medical Group Inc:

Desired outcome: I would not mind taking another to straighten this out but the clinic has dropped me

Quest Diagnostics Inability to speak with a 'real' person

I was forced to use the automated appointment system for a CDL physical . Nothing on the phone system for the Myerstown (Pennsylvania) Quest Lab said that they cannot do those test there. I drove to the site this morning (1/14/22) only to find that they do NOT perform those tests at that site. Perhaps the website should indicate what testing can be performed at a site?

Desired outcome: I need to know where I can go for the CDL physical that I need for a job I will start in the near future.

Quest Diagnostics Process of wait time

I knew when the appointment app didn't work, I was taking a risk going into the quest office on Binz in Houston. I decided to risk it, especially when I could simply wait in my car to receive a text to come to the waiting room. The issue- inaccurate information on when to come to the waiting room. Their message to "come now" turned into an extra 30 minutes and counting. The system is faulty and demeaning of everyone's time. Good thing they didn't need to take my blood pressure. Also, staff did not ask unmasked clients to wear one. Not good.

Desired outcome: Better serve and better system of call backs

Quest Diagnostics Incorrect billing and application of insurance payments

On March 18th, 2021, I went to the doctor for my wellness check. I received a bill from Quest Diagnostics for over $1000 of preventative labwork. BCBS paid, but the bill was not updated to reflect that payment. The Since then I have been sent to collections even though I have been on the phone with them 3 times a month at least trying to resolve this careless error on their part. They made multiple notes about this conversation, and it did not matter. SUpposedly there is a new billing system that has not been refined yet.

Desired outcome: removed from the collection agency along with the bill reflecting all the payments from the insurance company.

Quest Diagnostics Lab Billing

On Aug 13, 2021 My husband went to Quest to have labs drawn. He is a private pay patient and while our daughter works at the other lab in town, we were told they were less expensive for private pay. We asked their policy when we got there and were told that we would get a private pay discount for paying at the time of service. I have two receipts showing we did this as they separated the labs from the admin fee. The receipt shows a break down of codes and charges for each lab he had drawn. I have called and emailed them regarding this issue at least 5 times. I have been told that they put the wrong "discount code" on the bill and that is why it is not billing correctly, however, they cant fix it and I need to submit an email to the billing department. I have done this 3 times and each time it comes back as daemon mail. I work for a large heath care facility as an administrator and sent this from my work email and once again it was returned unopened. I also faxed the receipts to one of the customer service agents who was trying to help me but it has yet to be resolved.

Desired outcome: Write off the balance bill amount

Quest Diagnostics Service Center - Zip 95608 on Fair Oaks Blvd

I had an appointment today at 8:30am, I was in your lobby at 8:20am, I checked in. At 8:32am I received a text that you are ready for me. At 9:04am I walked out of your Lab without my blood work being done, nobody ever came out to get me. There is NOBODY at your window, there is NOBODY that comes out to check if people with appointments haven't been seen. It is UNACCAPTABLE that you make me make an appointment and you are late without saying ANYTHING to me. Calling your locations is a JOKE! No live person answers any phones, you cannot go up to the window to ask anything because there is no one ever there.. I have given you guys many chances. I have requested for my Dr to transfer all my lab requests to LabCorp. Incase anyone cares to correct anything which I highly doubt, the location is in Carmicheal CA 95608 on Fair Oaks Blvd. Totally incompetent people work here. Nobody has the curtesy to check on ANYONE in the lobby. I will be filing complaints against you guys with everyone and anyone who will listen to me. My husband has 6.3million followers on Instagram, so expect to get a lot of calls in the near future. I will be contacting Local news. Someone needs to launch an investigation into how you guys run a medical business with NO live people, nowhere to turn, a ghost town..

Quest Diagnostics I was charged twice and not refunded

They charged my credit card twice and have not refunded me. I made a payment online and the next day they charged my account a 2nd time. I have called no less than 6 times about this, I have sent in screenshots of the two debits to my account and each time I call, they give me the run around and keep telling me to call back in 10 days. This is absolutely frustrating and I am very dissatisfied that they over charged me and have not refunded my money back to me yet.

Desired outcome: I need to be refunded the $25.96 for the additional payment that was withdrawn from my account unauthorized.

Quest Diagnostics Driver

I'm writing to report an erratic Quest Diagnostics vehicle. While driving to dinner this evening, vehicle #80873, NJ Licencse plate U94-NMU made an illegally turn and nearly hit my car. I was turning into Skyview mall in Flushing, NY when the Nissan vehicle came speeding from the right lane and cut in front of me without any turn signal or warning. I had to veer into opposite traffic to avoid a collision. After I beeped my horn at her letting her know of her wrong-doing, she responded by throwing her middle finger at me. I was extremely appalled by the dangerous situation I was put in and how obscene the driver was. I would hope this is not the standard that you hold your employees to, as it definitely reflected negatively on your brand. Thank you for your time.

Quest Diagnostics Billing

I was charged twice for the same service by Quest Diagnotics. The first was paid by my insurance, which told me I wouldn't owe copay. Later I get a bill for the same amount sent to my provider... I wasn't sure what was happening so I paid the bill (in order to avoid being sent to collections.) I then went and looked at my insurance page and realized I did not in fact owe quest anything. I sent an email to customer service with all the information needed and haven't heard back.

Desired outcome: Refund of money

Quest Diagnostics Appointments

Today, December 16, 2021, I went to the Quest diagnostic center at 19582 Beach Blvd., suite 300 in Huntington Beach, CA. After several people had signed in and waited for over an hour, Isaak came out and announced that Quest no longer accepts walk-ins. Note: Every name on the electronic board said "Walk-in". I pointed this out to Isaak. I asked why my and others names were accepted and given a wait time as a walk-in and was told "I don't know".
My walk-in was for a diabetic check that requires fasting before the test. The time at rejection by Isaak was 12:00 noon. I* had not eaten anything since the evening before - as required for a fasting diabetic blood test. Isaak told me that I should pay better attention to me health as HE isn't responsible. I now check with the Quest web pages and I see where it says an appointment is recommended. I called the location where I was rejected after 30 minutes wait and another elderly gentleman was rejected after one hour (there were only 4 people waiting - all walk-ins). The Quest locations machine informed me that "appointments are recommended" and will be will be taken in order of arrival AFTER people with appointments - THERE WERE NO PEOPLE WITH APPOINTMENTS. I must say that the attitude of Isaak was that of one who deems himself most powerful and will dictate policy as HE sees fit. He told me it was company policy. Why not a sign out front advising people of that policy BEFORE they wait for an hour and then are told to go home. This is unacceptable.

Desired outcome: I want the true policy to be known and visual notice of the policy posted at the testing centers and on web sites and on teloephone appointment sites.

Quest Diagnostics Payment sent to quest in error

On October 3, 2021 I accidentally sent a payment through my dollar bank online banking to quest in air in the amount of $325.81. Dollar bank and I have been trying for two months to get my money returned to me to no avail. I have spoken to several supervisors at quest and they have told me it will take 4 to 6 weeks after the check has been processed. The check was cashed by quest on October 14, and I have still not received my money or any response to my emails. I have sent several emails and every time they just get back to me with a new case number. This is also the second complaint I have filed with you and never received a response. Dollar bank is also trying to get this money returned for me and they haven't had much luck either. I am finding this so unbelievable that I cannot get my money returned to me

Desired outcome: Having my money returned

Quest Diagnostics Driver preforming dangerous driving in unsafe conditions

A driver in a Quest Diagnostics vehicle numbered 15750 was going above the speed limit today 12/6/21 at 1pm. Southbound on division between Wellsey and queen. The driver was driving much too close to other drivers and honking at turning vehicles. The current date is also the first large snow of spokane this year and this is unacceptable. The driver in question almost rear-ended another vehicle due to this irresponsible driving choice in a company vehicle. I hope you can understand how unprofessional this looks towards your employees and business.

Desired outcome: Driver will be told repercussions of driving this way and or be limited to dry weather driving.

Quest Diagnostics Labs

On June 2020, my employer ordered labs . Quest diagnostics had my address incorrect. I have worked for the same doctor for 5 years my address and phone number have not changed. I never received a call or bill for over one year . The only way I knew of this bill was from the collection company that contacted in November of 2021 over a year later . At my employer it is policy that the office covers all lab work after our insurance is billed. However my employer did not recur bill for labs . I now have this negative activity on my credit.
I am a licensed lab technologies and understand how lab work is done . I am truly disappointed that quest never contacted me . The bill is now paid however I will never use quest services again and I will strongly suggest to the doctors I work for to change companies and no longer use quest diagnostic.

Desired outcome: Off credit
