Last week I made an appointment to have my blood drawn on Saturday June 6th. My doctor submitted the order electronically to Quest. I asked the Quest rep who was helping me to verify that the lab order was in the system. She confirmed that it was. I went Saturday morning and waited and when I was finally called up the person behind the counter said that...

Quest Diagnostics Lab billing

Hello, I received a lab invoice dated 11/26/2019 from Quest Diagnostics. Called them the following day to verify they had my correct insurance info. They confirmed they did. Now they have sent it to a collection agency, because they submitted the wrong group number (per the collection agency). Quest Diagnostics will not help me, because they have already sent to collection. I told Collection I could not pay the 850.40, and they said it will go on my credit report. This is so unfair for Quest Diagnostics and Credit Collection Services to not correct this error. It was not my fault.

Quest Diagnostics Covid-19 test

Do not use Quest because if there is a problem, it will be impossible to talk to a human. Quest is dedicated to refusing to allow you to connect to human to fix problems. My test results are not available 4 days after Quest sent me an email saying the results were available at my on-line My Quest account. Not visible at my account or my doctor's office. When I try to email them, I get nothing back. When I finally find the customer service number it refuses to connect me to a person and hangs up on me (3 times). Now, I am trying the Quest chat bot. Once again no connection to a human. It has been telling me for 20 minutes that it is connecting me to an agent. Have you ever heard of this? I do not believe it will connect me to an agent

Quest Diagnostics Treatment of autistic individual

On April 29th, 2020 I went to get my blood drawn (it was a time sensitive test) and was not wearing a mask. I was then told that I must wear a mask or that I will not be allowed to get my blood drawn. I then went to explain I have autism and they said it doesn't matter that I still have to wear one. Being autistic makes me unable to wear a mask but they didn't care and told me and my dad to leave. I am very upset over this matter and was very disappointed at the care I received.

Quest Diagnostics Customer service

I have my blood drawn at least 2-4 times per year. I waited about 5-10 minutes although I was the only person there. Usually staff is friendly and try to put you at ease and always use a butterfly needle. Yesterday, a larger needle was used. The woman (Ronda I believe) argued with me when I told her it hurt and she accused me of jerking my arm before she inserted the needle thus causing my pain. That argument is not even logical. She stated it was my responsibility to ask for a butterfly needle, yet since that is what the other ladies do, how would I know that. Her tone was disrespectful and argumentative. I don't believe the customer is always right, but I have a big, red, bruised bloody mark on my arm due to her incompetence. She needs re-training.

Quest Diagnostics Billing

Complaint/Grevenice against Quest Diagnostics Billing
INVOICE# [protected]
I am so frustrated that Quest would have such poor due diligence and poor customer service-billing department.
My insurance company confirmed that I owe ZERO nothing, Fact: Tricare is under CONTRACT AMOUNTS with Quest Diagnostics, Fact: I am In-Network coverage, Fact: I have $0 copay, Fact Insurance has sent Quest several policies and regulations, EOB letters, Fact: The insurance company sent several requests for a letter of explanation or LOA was billed improperly the test(s) performed did not match the diagnosis on bill and is waiting on Quest Diagnostics.
LINE #12: 81270, LINE #13: 81403, LINE # 15: 81402, LINE # 16: 81479 LINE # 19: 81256- 81256
This is why it was simi-rejected.
TRICARE coverage of certain limited benefits is subject to specific clinical criteria. A letter of attestation (LOA) can be submitted, in lieu of additional clinical documentation, when requesting authorization from Health Net Federal Services, LLC (HNFS) for these services.
My Tricare insurance representative was extremely helpful and reached out to Quest to try and resolve this issue and Quest doesn't take action to resolve anything.
I have called Quest multiple times and everytime Quest agreed that they will get the information for my insurance company and would place a 30 day hold on the bill and everytime, Stated they would get it resolved. Well, Now it's been 13 Months-on going and nothing has been sent to my insurance company and Quest is threatening me to a collection company.

DOS: JANUARY 22, 2019
AMOUNT: $4, 099.24
ADJUSTED: $1, 664.16
INS PAID: $200.77
TOTAL IN DISPUTE: $2, 234.31

Quest billing Dept will not respond to my requests and just ignored the issues, in hopes I go away or to collections! This demonstrates bad business practices on their part and a clear indication that they were unwilling to help resolve a billing issues. A year has past and they could have referred us back to the doctor's office to get this correct but they chose to just ignore the issue and continued to bill a incorrect- fraudulent bill and send me to collections.
Quest has a financial gain to do this.
My insurance company has explained to me how this works!
A provider like Quest will get a contract with an insurance company. The insurance company will monitor billing amounts not allowing over inflated bills, by a list of what they are allowed to charge under the contract. If provider like Quest does anything fraudulent, Quest could/will lose the insurance contract.
My insurance company Tricare - Health Net Federal Services, LLC (HNFS) is well aware of this, have reported this "Balance Billed" problem to the Tricare contracts department for a full complaint review. My insurance company advised me to make a grievance report to Quest Quest Diagnostics.

I have Anthem Blue Cross PPO insurance provided by my former employer. Yesterday, 10-26-2022, I received a letter from a debt collector, Radius Global Solutions, LLC stating I owe/should pay $236.67 for "serivces April 21, 2021...I was never notifed of this by anyone. Amarillo Heart uses Quest. Billing has been a problem before, but LAUSD was able to help the company with billing...I have had to phone LAUSD to initiate help...Being retired for some 25+ years, I cannot afford to pay this; the fact is the price, $236.67 is "inflated" from what my Anthem Blue Cross PPO would pay.

Quest Diagnostics blood test

My husband an I have been going to you Bethpage facility for years. Today I had a appointment which I make on line as usual and today I was accused of lying by one of your employees. She was taking people ahead of me after my appointment time. She was very nasty and let me walk out with the rubber tie still attached to my arm. I strongly considering of finding a new facility.

Quest Diagnostics reckless driver

I was following behind a driver from quest and they were swerving in and out of traffic at about 60 mph. The speed limit is 45 and it's a construction zone. The driver never used turn signals, was tailgating a vehicle and then cut in front of another vehicle with barely enough room to do so. I believe the number on the car was 31030. It was in Yulee, Fl.

Good afternoon, As a Corporate credit manager for over 37 years, I really did not want to give a credit or debit card out when having blood drawn today. Especially since I pay my bills. I really think Corporate should be made aware that customers do not like having their credit cards out there. I can see if there is a balance due, but for heaven sake...

Quest Diagnostics reckless quest diagnostics vehicle driver

As I was pulling out of my work, mosaic in Riverview FL, a quest vehicle sped past me in the turning lane only to cut me off in my lane almost running me into oncoming traffic in the middle of an intersection so that he did not miss the light. I am assuming he did not notice he was in the turning lane to turn right and swerved right in front of me screeching his tires. Completely reckless and almost caused me to have an accident. The vehicle number is 78453 and the tag number of the vehicle is KUBY98 and this occurred around 4:30pm on Thursday November 14th at the intersection of US Highway 41 and Riverview Drive In Riverview Fl. Not to mention he was tailing me pulling out of the plant when the speed limit is 14mph. I am completely appalled. I do have a picture of the tag of the vehicle as well.
