Quest Diagnostics Billing

My husband had a kidney transplant. He has primary health insurance through his employer and secondary through Medicare (yes, it's secondary). He has been going to Quest for his labs, and they correctly bill the primary insurance. They say they are submitting the bills to Medicare also, but Medicare has not received any of the lab bills. Every time we call Quest billing, they say they're working on it. Last month, we called Medicare, and they confirmed they haven't received a bill. We then called Quest again, and the person acknowledged there is no record of Medicare being billed. She said she would put the account on hold again while they bill. However, we are still getting bills and threatened with collections by the lab in Gardner, Massachusetts. The lab in Gardner is now making us pre-pay for testing that we don't even know if we are liable for - this seems illegal as Quest is the one messing things up. We just want to know what we owe so we can pay it. I don't know if this is Quest willfully playing a game because they don't want to deal with Medicare or if they just don't know how to deal with Medicare as a secondary payer. We're tired of living in limbo - we just want to pay what's owed, but until both insurances have been billed, how do we know what's owed?

Desired outcome: For Quest to bill both the primary AND secondary insurance. After billing both, let us know what, if anything, is owed so we can pay it

Quest Diagnostics Quest charged wrong insurance after being told numerous times (now sent bill to collections)

So I was on a program for my addiction and the doctors office and quest had some deal hooked up so that I was forced to go in every week and get a drug test sent to a lab despite multiple requests to not do this as it was a hassle when quest would send out the bill to only ONE of my insurance companies. I have Mass Health and Medicare so I know that one covers the stuff the other won't and I never end up having to pay out of pocket for anything.

Despite this, I recieved not 1 but 8 separate bills all for $120. Reading them you could almost think I only owed $120( Though the collection agency they forwarded it too is trying to ask for $960 ). I obviously called both my doctors and Quest to inform them they must have been charging only one of my insurance carriers, after waiting HOURS on hold I finally was able to talk to someone who said they could fixed the issue and that it would take some time to go through but that it should no longer be a problem(this was in august of 2021). Fast forward to now, I've moved and changed jobs and don't even go to that doctors anymore and yesterday I get brought mail from the person who lives at my last house that says I owe $960 to a collections agency "ARStrat".

Well I know that I shouldn't owe this money simply because of the insurance I carried at the time, the phone calls I had with both my doctors office and Quest, and because I was told BY QUEST that it was all taken care of. So I will be contacting my attorney, my insurance company, news media agencies, my state representatives at the state and federal level to inform them of this disgusting practice. No wonder medicare recently told these kinds of providers that they would only cover 1 visit a month starting this year, because Quest and these offices had some sort of deal worked out forcing me as a patient to go in every single week no matter what so they could fleece me and my insurance companies. I probably never would have noticed or cared if they had just billed my insurances correct but now... This is just disgusting.

Desired outcome: I would like my bill to be clear from collections.

My husband went to Quest Diagnostics today to turn in stool samples. He waited an hour. The practitioner took him back to a room (no apologies for the long wait) and asked for the stool samples, of which there were four. She set them aside and said the samples were a little above the line and threw the samples away. She then gave him new bottles. Now he ha...

Quest Diagnostics Billing

I reached out to Quest Billing Department and was told that I had a balance of $0 and everything had been cleared up. I was informed that the billing codes had been corrected. This occurred last year. On today, I received a bill for the same amount that I was told was cleared up. I contacted my insurance company and was told that they paid the bill and Quest submitted the same claim multiple times. This is a horrible unorganized company.

Desired outcome: I want this $117 bill to be cleared up.

Quest Diagnostics Lab test

I have no other option but Quest Diagnostic because that is what the insurance request (uses). In May 2022, I had a lab work done requested by my physician - there was a billing problem and the bill was resubmitted to my insurance company to revisit and possible cover. During this period it took a few months, I did not hear back until Quest sent me to collections without sending me a final bill. I had no idea that the insurance did not change anything - Quest did not inform me in writing. I contacted them when I received the bill for over $700 to arrange a payment plan, which I started and continue to pay currently. I now have my anual lab due in order for my doctor to renew my prescription - that I must have. I got my order and went into their Palm City location, I was denied the blood work and told If I don't pay up - I cannot have this lab. I need help! I need this medicine to regulate my desease. How can I get them to reconsider their heartless/unethical business practice, I am making monthly payments.

Thank you.

Desired outcome: I would like to have my lab work done.

Quest Diagnostics Routine pre-employment urine Rx screen

Had appt. Arrived & checked in electronically 10 minutes early, as directed. No H2O available in waiting area or in lab. No staff interaction. Tiny, drab waiting area. Persons arriving & checked in after I had done, were received into the tiny, claustrophobia-inducing lab area before I was. Total wait time 40 minutes. Total time in lab, 4.25 min. I'll stick with Labcorp. No contest.

Desired outcome: Compliance w/appointment time or apologize for wait. Common decency, would be appreciated.

Quest Diagnostics Lost six valves of blood

On 3/27/2023, a blood order for a hormone therapy appointment was scheduled for 4/03/2023 appointment with my doctor and rescheduled to 4/06/2023 since the results were not received. Today, I received a call from the doctor's office stating they were still waiting on the results from Quest. I called Quest customer service at [protected] to learn that my blood samples were missing and I would need to submit another sample. I was given this confirmation number, #341795, for reference. Quest has not notified the doctor's office of the samples being lost.

Quest Diagnostics No butterfly needles at many locations.

I have used 3 different places of the Quest locations. I do not have an easy time finding my veins. I am 66 years old . They do not have any butterfly needles at Coral hills: location or Oakland park. Many of the girls have no idea what they are even doing. I am tired of getting stuck 6 times and no one can find a vein. It is beyond scary. In my opinion, every location should have someone that has a lot of experience drawing blood on easy patience and more difficult patience, Many of the girls do not even know what they are doing. It is mind-blowing. This is people's bodies and health. Some girls are very nasty about it too. YOU use to be very good. BUT NOT ANYMORE.. It is pretty scary when one of your employees tells me they don't have butterflies needles there because they are very expensive. This is what your employee said to me. That is just gross. very negligent to your patience. Quest I am sure make enough money to get proper equipment in drawing blood. Shame on you all... Please get your [censored] together. I am going to call my insurance company and hopefully find a new place to go...

Quest Diagnostics Attempting to get blood drawn

This morning at 6:30 AM I presented to Quest for a Vitamin D level. The order was on an appropriate order form from the ordering physician’s office along with contact numbers including a dedicated fax number to send the results back.

The phlebotomist started to refuse to draw the requested blood draw for the test because the Dr’s “NPI” number was not on the form. I would think that Quest would have the doctor’s information and NPI number in their system. It all boils down to the fact that she didn’t want to do the extra work of looking it up. Shameful! This type of nonsense does not need to happen as it causes undue stress on me. It seems every time I go for labs I’m anxious and full of anxiety just waiting for another excuse to not draw my blood. I’m considering taking my business to lab corp.

Desired outcome: I’d appreciate a response and explanation of why not having an NPI number on a lab request is a reason to refuse to draw the sample.

Quest Diagnostics Employee

Kristin Caputo, phlebotomist with Quest diagnostics at Woodland Primary Care takes long, extended and frequent breaks. she is rarely in her designated lab area when patient's need their blood drawn the patients have to wait for her to come back or other employees with RCCHC have to draw the blood. she comes to work late and leaves early numerous times during the week and calls out frequently. She has been seen watching explicit videos at work in the lab area on her cell phone. She has reported to a nurse with RCCHC that she has been using drugs and took a urine drug test herself at work which was positive for cocaine after using from 2:00 am - 6:00 am then reporting to work that same day at 8:00 under the influence. She repeatedly comes to work unclean and unkept. She leaves her trash in areas not designated for trash. Employee is very loud, excitable and disruptive and

Desired outcome: I believe the hiring manager needs to visit the office of the employee and have the employee complete a random drug screen.

Quest Diagnostics Extremely poor service from an employee

My complaint involves one of your technicians who was not only incompetent. She has a very bad attitude. I am an adult white male who went into one of your locations at around 10 a.m. on Thursday, March 2 to have blood drawn for a Tegretol level. I went to the location inside the Tom Thumb store on Firewheel parkway at Pleasant Valley in Garland, Texas. I signed in and set down waiting to be called. I was called into office #2 by the Tech. After verifying my name she told me that she did not have any orders in the Quest system for me. This is when she became very surly towards me. When I said "Poor little snowflake" in response to her hateful attitude toward me. She then told me to leave. Which I did.

So I went back to my doctor's office to get hard copies of the order and the Quest confirmation. When I returned with both documents in hand, she refused to wait on me because in her words "I had been rude to her" after she became nasty towards me. She then locked her office door and left the facility.

So, I sat down and waited for the other tech to wait on me. I then presented her with the same documents. She had no problem whatsoever in finding the original order and the Quest verification. She took care of business and I left with no confrontation whatsoever. We got along quite nicely.

I just did not appreciate the attitude of the first tech. I got the distinct impression because of her attitude toward me that she did not want to wait on me at all because I was a white male. I did not know that was a qualification for service at Quest.

Desired outcome: An apology from the first tech for the way she treated me.
