My child has been a patient of Dr. Klausner for six years, and while we've appreciated the care over the years, I am extremely disappointed and frustrated with the way the billing for a PCR test from October 2024 was handled. During a sick visit on 10/25/24, a PCR test was administered. I was required to sign a waiver stating that if the test wasn't covered by insurance, I'd be responsible for the $175 fee. That was understandable. However, things went downhill from there. In December 2024, I received a bill for an annual membership fee, showing a $200 line item but only a $175 total. Since we had recently moved and changed doctors, I called the office and was told to ignore the bill. I was never told about any other outstanding balance. A few months later, I received another bill for the membership fee and was again told to disregard it. Then in June 2025, I received a phone call out of the blue stating I had a $175 balance for the PCR test from October -- the first time I was ever told about this. I was shocked. I requested a copy of the bill and called my insurance. We had a three-way call with Sandra from Dr. Klausner's office. During that call, my insurance confirmed the test was covered, but it was billed incorrectly using CPT code 87631 instead of the correct, covered code 87633. Because their office waited over 90 days to inform me of the bill, it was now too late to resubmit with the correct code. I was never contacted, texted, or emailed about this charge until June 2, 2025 -- far too late for any corrections. I even shared the original bill they sent me to Dr. Klausner's staff showing the yearly fee line item -- which seems to confirm they initially billed the wrong charge entirely. Despite this, the office insisted they had been billing me since November -- which is absolutely untrue. I confirmed with my insurer that they didn't receive communication from Dr. Klausner until 12/31/24 about the PCR test. Unless Dr Klausner's office has a habit of sending patient's bills for covered items before sending them to insurance first, which is also not acceptable. To make matters worse, according to Mary in the office Dr. Klausner claimed she would never use CPT code 87633 because it "isn't for pediatrics" -- something my insurer confirmed is not true, as the code is not age-specific. I finally received my first-ever billing text from the office on July 7, 2025, threatening to send me to collections if I didn't pay the $175 by July 11 -- just a month after I was even made aware of the issue. I paid the bill simply to avoid further stress, not because I believe it was right or fair. Bottom line: This office's billing department is disorganized, uncommunicative, and unwilling to take accountability for their mistakes. If I had been informed earlier, this bill would have been fully covered by my insurance. Instead, I was misled, gaslit, and forced to pay out of pocket due to their error. I write this review so others are aware: If you choose this practice, stay on top of your billing, keep records, and advocate hard for yourself -- because the office certainly won't. read more

Kimberly Klausner, MD - Miss labeled bill - Pediatricians Near Me - Los Angeles, California

We drive from the valley to see Dr. Klausner in the city because we value her care and expertise that much! She confidently and calmly diagnoses any kid sickness or issue we throw her way. My kids love her, and so do dad and I. I trust her guidance for our children's health and feel lucky to have her as our pediatrician! read more

Dr Klausner is a great doctor, but the front desk, especially the "office manager" Nicole is a very difficult person to deal with. Abrasive, argumentative, dismissive, condescending. I've noticed that the same attitude is spreading to other front desk staff. Keep in mind, that when the doctors are around, Nicole et al are the "nicest" employees ever. I wish Dr Klausner and Dr Efron could hear how they talk to the parents over the phone. We are leaving this practice. read more

Dr. Klausner is amazing and can't say enough about her ! unfortunately the receptionist is super rude and disrespectful over the phone every time ! dr klausner gets 5 star and receptionist 1 star ! read more

Amazing, thorough, and very experienced. Dr K spends time and listens to her patients and always offers solid and practical advice. We love coming to see her. read more

Dr. Klausner is knowledgeable, informative, and confident. All things you would expect from your doctor. She is also extremely patient, kind, calm, warm and giving of her time. These are the extras that make you feel comfortable and connected with a doctor. Dr Klausner is not our primary pediatrician, which makes it even more remarkable how patient she is. I never worry if my doctor is not available because I know we are in great hands with Dr Klausner. She spent most of her lunch hour the other day answering questions for us (that weren't even medical). She puts my daughter at ease, and my husband and I as well. I'm very appreciative that she is in our lives! read more

Dr Klausner is nice HOWEVER the staff at this office are so horrible I switched to a new pediatrician. They are unethical as they are constantly double billing the patient. I have contacted the billing office after every single appointment to prove that I already paid for the visit!!!!!! The front desk talks like you owe them something and that they are annoyed to hear your voice. You almost have to apologize for asking a question. Horrible office. Dr. Klausner should move to a different office if she doesn't want the awful staff to ruin her practice. Although.... I'm not sure how much of this behavior she's approving of over there.... read more

I had a very poor experience with Dr Klausner and this office in general. Let's skip over the part where she hit my baby's head during her first visit to us in the hospital and didn't apologize...every appointment and question was treated with annoyance. They repeatedly scheduled appointments for things like shots and when we would show up they'd say oh the dr isn't here today and anyways you can't get those shots yet. The worst however was when my infant was vomiting and I called their after hours number and they NEVER returned my call. To add insult to injury the office staff is rude and unfriendly. So glad I left this practice to find a legitimate doctor instead of this hack. read more

I truly loved Dr Klausner when we first started. Sadly my son had an issue and was repeatedly misdiagnosed. On one visit he in severe pain and vomiting and she said "only thing I can definitely do is rule out appendicitis." And then she gave him Zoltan. It made him much worse. We saw a gastro the next day. She hospitalized my son and he had an emergency appendectomy. DR Klausner then stopped by his hospital room 2 days later. I mistakenly thought it was out of kindness. She then billed me. When I called her about the bill... yes, she billed me!... she humiliated me by saying it was a nominal amount. Sorry I'm not wealthy. She waived the charge and then "fired" us from her practice! Blessing in disguise! On top of all that, well child visits that have always been fully covered by my very good insurance cost me $100 per kid! Now we have a phenomenal pediatrician read more

Dr. Klausner has been our children's pediatrician ever since 2012 when we moved to California from the east coast. She is knowledgeable and up to date with her care and recommendations. My husband and I are both physicians and she was recommended by another colleague. She spends time with each kid and we never feel rushed during their appointments. We definitely recommend her without any reservations for anyone seeking excellent care for their kids. read more

Dr Klausner has been taking care of my kids for almost 18 years now. My soon to be 18 yr old was her first patient from our family and we stuck to her ever since for the rest of our kids. She's very attentive, supportive, and the kids feel comfortable with her. Love that they do have a "call center" in the event that you need something at 8pm. It's a commute for us since we are closer to Long Beach, but when you go in once, maybe twice a year, for the kind of attention you get, it's well worth it! Thanks Dr K for making a difference in care for our kids!!!! read more

Love Dr. Klausner. She's been such a sweet and caring pediatrician for our daughter. Always accessible. From the first day we cold called over a decade ago with a minor head wound, she took us in sight unseen and has been wonderful ever since. Big fan! read more

Dr. Klausner has been my daughter's pediatrician for about 3 years and my son's since birth, 15 months. My husband and I both love Dr. K. Agree with some reviews that she is not warm and fuzzy; she does not coddle you and is very honest and practical in her approach. I appreciate and relate to this kind of attitude. She is smart and knowledgeable. I would not tolerate rudeness and I've never found her to be rude or unprofessional. There are times when the office is running behind (probably due to patient late arrivals) and we've had to wait at most 30 minutes. I think you would have delays at any doctor's office though. As far as Dr. K, we have no complaints. You can even send her a quick email if you have a question which I have done many times and she has always responded within a few hours. Thanks for all you do to care for my kiddos, Dr. K! read more

We've been with Dr. Klausner for five years. She's a very fine doctor and once we found someone good we'll stick with her until our insurance says otherwise but her billing department is a demon from hell. (It's a solitary woman.) I would hesitate to recommend beginning a relationship just because of that. If you use insurance, sometimes problems arise through nobody's fault that need resolution. Not difficult problems, but problems like rebilling under a different code or just talking to someone. Unless you speak demon or enjoy being abused, this won't be fun. However, as soon as billing changes, five stars! read more

Dr. Klausner has been my daughter's pediatrician since birth to now a healthy 12 year old. I have completely trusted her medical guidance and have full faith in her impeccable care and service. She has helped us with simple colds, nagging coughs to more serious anemia problems. It's a 45 minuet drive for us to reach the office, but her professional care is well worth the inconvenient commute. read more

After 5 years we finally made the move to switch offices! As time went by the office staff became ruder and ruder and the wait times became longer and longer (I'm speaking on average an hour - sometimes more, just for a wellness check up). I was not the type of parent to constantly call the doctors office, but the handful of times I did in the several years my daughter was a patient there, I never got a timely response. This last time was the straw that broke the camels back, my daughter was really not feeling well, and instead of them giving me a sick visit, the front office told me they don't have any open slots and to take her to an URGENT care, seriously? I begged them to let me speak to Dr. Klausner and they said she has back to back patients and can call me the next day after all her appointments. Anyone who has little ones knows that is so UNACCEPTABLE. I ended up taking my daughter to urgent care and never once did I get a call back from the office or the doctor. I ended up transferring to another pediatrician and let me tell you, its a world of difference, we are treated so nicely. Fast foward 3 months after switching pediatricians, they made me pay everything in full before transferring my children's records, no problem we did that. All of a sudden I am getting multiple bills in the mail of over 1k (we have in network insurance). I called to try to speak to them, and the front office keeps hanging up on me, telling me my insurance didn't cover it from over 2 years ago!!!! After spending hours and hours with insurance, the office DROPPED THE BALL AND NEVER SUBMITTED THE CLAIMS, now they are out of the window to do it and are trying to back track bills on me for 2 years ago. I would be very careful with this office. After reading the other negative reviews, looks like I am not the first one who is trying to be billed unethically. Luckily insurance has deemed that this is there responsibility, but this is just an example of how this office operates. STAY AWAY! read more

This pediatrician seems to prioritize business over caring for kids, exercised some unprofessional behaviors - will not bring my child to this office again. One of the things that has rubbed me the wrong way was charging insurance for the "office visit" when the child wasn't present and, basically one of the parents just came up for an advice. read more

Dr. Klausner (Dr. K) has been our son's pediatrician since the day he was born twelve years ago. She's amazing. She's incredibly knowledgeable and not an alarmist (which is exactly what I need as a neurotic mom). She has a terrific, easy going rapport with our kid... he never minds going to see Dr. K. She's made it very comfortable for him. And if we've needed a specialist, the people she's referred us to have all been outstanding. Dr. K is caring, thorough, and we trust her guidance implicitly. read more

Dr. Klausner has been my kids doctor since my son was born (2007). Whenever my kids get sick she always comes up with wright diagnosis and treatment. She saved us from going to emergency room so many times. last week, my daughter had insect bite. We treated her with over the counter medication. Over the weekend her bite site got worse. I called office and also I emailed Dr. Klaussner. She emailed me right away, even before the oncall doctor get chance to call us back. She gave us advise what to do. We are so lucky to have her as our kids pediatrician. I recommended her to my cousin, when she was expecting and looking for pediatrician. She is also very happy with care she receives for Dr. Klausner office. read more

Best pediatrician we have seen. Wish we had gone to her for my first kid. I like how smart but down to earth she comes. I feel like it is more of a partnership in making sure my children stay healthily or fix them when they aren't. Phenomenal bedside manner. She also gets what real life is like not what a textbook has said. Truly an asset to any family. read more

I am a health professional , I took both of my daughters to Dr. Klausner for years , so did some of my friends. She is fine doctor but she seems very bored at her job . When my daughter was overweight I asked her how many calories a child her age should have and her response was " I don't do that ! " I would think a better response would be I think this or that but maybe it's best if we refer you to a nutritionist not what she said . After this comment I switched to one of her associates. When I discussed the front desk gum chewing girl and how they answer the phone and their lack of phone etiquette, the associates response was " I just work here ! " I transferred out of this office and so did my friend . My advice from one practitioner to another is care more about your patients and staff etiquette is very important . read more

Dr. Klausner is fantastic and I feel so lucky that we've found her. She's got a terrific bedside manner, she's whip smart, funny, and she is great at easing first time mom worry. She even responds to questions via email which has been enormously helpful for us. One other thing: she won't put up with any BS, which I truly appreciate. So if you have some parenting ideas that have been thoroughly disproven, i.e. about vaccinating, she would likely try to set you straight and then let you know that her practice won't be able to accommodate you (so maybe that's why Heidi gave her such low marks; it's the only thing that makes sense to me). I also really like the fact that she's about my age and very internet savvy, so I know she is always giving me the most up-to-date information. We could not have found a better pediatrician. read more

Fantastic doctor!!!! My favorite Pediatrician in Beverly Hills. She is kind, patient,knowledgeable, and has the best bedside manner of any Pediatrician I have ever had the pleasure of meeting. Her office is clean and the staff is superb. Five stars all the way! Thank you Dr Klausner for all your help. read more

We've been with Dr. Klausner for all 3 of our daughters, starting at her former practice and moving with her when she opened her own. We even stayed with her when our insurance changed briefly and we had to pay out-of-pocket. Dr. Klausner recently caught a serious health issue with our 8-year-old during her annual checkup via a test that for her office is routine, but which other parents have told me their doctors don't do (sorry to be a bit vague here but I'm protecting my privacy). We love Dr. Klausner & her practice. read more

Dr Klausner has treated my son for two years. I am a mom and also a physician and chose her based on her training. She is thorough and clearly cares about her patients. She gives me detailed information when we have any questions and is always available by email. Her office recently stopped accepting individual health insurance plans but I decided to stay on and pay out of pocket for my son to see her because she is thorough, academic, and knows what she's doing. Their insurance manager is quite abrasive but that's not a reflection of her as a doctor. I can't imagine how any child wouldn't like her, she is so sweet! So I have not had the same experiences as some of these reviewers. I would highly recommend her to any of my friends or colleagues. read more

Dr. Klausner has been our pediatrician since my first daughter was born, almost 5 years ago. When I interviewed pediatricians while I was pregnant, I was struck by her down to earth approach, her warmth, and her understanding of my parenting goals. At each well visit, she has us come into her office after the checkup is done and asks, "What questions do you have for me?" And she listens and responds to every single one. She never makes me feel rushed or that I'm wasting her time. She treats my daughters with respect - telling them what will happen, asking them what's wrong, etc., instead of talking over their heads to me. She is warm and caring and reassuring. She is everything you could want in a pediatrician and then some! read more

Dr. Klausner is one of the best pediatricians in LA. She is super-smart and straightforward but also very warm and caring. We never have to wait more than 5 mins and her office staff is very nice and helpful. Couldn't recommend her more highly!!! read more

I will NEVER go to this office again. Not only is her reception staff EXTREMELY RUDE, but they bill you even after you've already made the necessary payments. Their bookkeeping is HORRIBLE. read more

Dr. Klausner is the BEST!!! She has been our family pediatrician for 5+ years and we couldn't be happier with her and the practice. Our son had RSV, pneumonia, etc when he was a baby and Dr K held our hand (and kept us out of the ER) the whole time. She practices cutting-edge medicine but also doesn't get wrapped up in the hype of new practices until they have been shown to be better than the standard recs. My daughter didn't tolerate vaccines well so Dr. K allowed me to make extra visits to spread out her shots. My kids love her and actually like going to the dr! As an aside, I love that they have a separate sick waiting room and Saturday sick hours as we have used both many times! You will always be in good hands with Dr. K! read more

Dr Klausner is the pediatrician you only wish you could have as an adult. Her manner is warm and friendly and never alarmist. While incredibly thorough, she is never the one to order additional tests without cause. In emergency situations, she has even been able to diagnose our kids over the phone or after a picture has been sent to her. Both of our children (girl and boy) adore her and she gives excellent referrals. Nicole in her office is a gem! read more

One extra star because Dr. Klausner is actually a knowledgeable doctor by my understanding and opinions I got from other people. However, her eyes rolling and rudeness ( which I have to agree with the other review) is very unprofessional. I also dread seeing her or even speaking to her, but I had to do it for my child as everybody knows it's a bit difficult to switch baby doctors do to the fact that this particular doctor saw my child since the day he was born. I really wanted to like her, but unfortunately, it did not happen. I do understand dealing with moms every day could drive anybody crazy, but that is her profession. When my child was sick and I saw her at the office, she did not even bother to ask me why I am there seeing another doctor (because it was her day off); her associate. I really did not want to write a bad review about her, but I think I got to the point that I had to voice my opinion to other moms; if you have nothing better to do that take crap from your pediatrician this doctor is for you. read more

When we got the diagnosis that our son had a rare and severe neurological disorder... a diagnosis that was promptly forwarded to her from our gentecists... she didn't even call to check in. That was the final straw after a slew of mishandlings on the part of her and her staff. Could not recommend this practice less. read more

After struggling to figure out what was wrong with my son for months, I kept bringing my child in because he would cry and cry. She told me he was simply fussy. It turned out later he had severe allergies, and seizures. We ended up switching clinics because of the unprofessional manner in which we were treated. We had an emergency one night and needed to talk to her, but the other providing Dr was on call so we talked to him. He was incredibly rude and demeaning. He made us feel like we were a huge inconvenience, and ended up taking our son to the ER after they provided no feedback or help. The front desk girl was great, as well as the nurse. 4 years later I get a call from the billing dept saying we owed them and they were taking us to collections. We had moved and never saw a bill in the first place, and our insurance at the time had incredible 100% coverage. I asked that the bill be forwarded to our new address since it had been so long. They would not provide any help in sending me a receipt or bill and said that if it was not paid NOW they'd send me to collections! It had been 4 years and I had not heard a thing!!! They had my number the whole time, and they waited THAT long! I cannot believe how unkind and rude they had been with us. Yes, they live in a big city with lots of kids, but please be sincere and attentive. I was hopeful after she was recommended by a fellow Dr that she would be able to be a good fit, but unfortunately we found her to be demeaning, rushed, and not very sincere. She was not the right Dr. for our family and as soon as we switched, we were able to find a Dr that listened and my son was headed on the path of recovery. It's just unfortunate that no one listened the first 5 months of his life! read more

Agree with Naomi. I loved Dr. K from the get-go. The right amount of sass and no BS attitude while still being super loving to my daughter and even to me (i am a handful!), not to mention super smart and funny as hell. If you're used to people kissing your a$$ 24/7 I can see how her "to the point" approach may seem rude, but folks, she didn't go to school for half her life to chit chat about gluten-free diet while nursing cause your baby has a rash not caused by gluten at all. It's baby acne, will go away, move on... Thank you Dr. K for always sifting through "new age natural mommy" bullcrap and leaving me with useful,not to mention scientific, information only. You're a breath of fresh air. read more

We see Dr. Klausner for both our daughters, one of whom is quite a handful! They love her (when not getting shots) and so do we. I have the highest regard for Dr. K's care and have referred her to multiple friends, all of whom share the same sentiment. Her personal mannerisms are just fine, I find her honest and unglamorized approach a refreshing change from the mechanized, impersonal approach most doctors utilize these days. That "eye-rolling" someone mentioned isn't judgmental - she has children of her own and has gone through the exact same rollercoaster ride. She's just trying to tell overwrought parents not to worry so much, to relax and assume everything is okay, which apparently isn't what some people want to hear. Me? I find her invaluable - a source of calm inspiration amidst these hyper-polarizing, hyper-dramatic times. She's a keeper. read more

Dr. Klausner has provided our children with excellent medical care for the last fifteen years. She is smart, has an excellent bedside manner and is excellent at explaining the medical details to both parents and children. I would not hesitate to call her for an appointment. read more

We love Dr. K. She is acutely smart which is what you want in someone who is diagnosing. We have been with her for 11 years and she has taken great care, not warm and fuzzy but to the point and always right on. read more

After a year with a pediatrician I did not love, I switched to Dr. Klausner. A friend of mine recommended her. I have been so happy ever since! She is calm and super knowledgeable. My son had this crazy blistery rash and within 2 minutes she knew what it was and what I should do! Her staff is really nice. Her nurse, Yani, is the best (which is really important because she gives the shots!). Thank goodness I switched! She is a mom herself, so I feel like she can relate to me as well as care for my kids. read more

We switched to dr k from a doctor who fit quite a nasty profile... To make a long story short... Everyone has bad days and good days but personally we never had any bad moments with dr Klausner. She has cared for all my kids as if they were her own and her knowledge and experience are very comforting. read more

My husband and I absolutely adore Dr. K, and so do all 3 of my boys. She's ready to listen to every question on my list and provide a well thought-out answer to whatever I throw her way. She tells it like it is, but always with compassion and a sense of humor. I find it invaluable that she responds promptly to emails and voicemails. When I've called the office crying, she's on the phone with me in a matter of seconds asking what was going on, calming me down, and explaining what (unlikely) symptoms to look for, while reassuring me (with facts and stats) that in all likelihood, everything would be fine. It's easy to see that she is passionate about being a pediatrician, and I could trust no one more to be our doctor. Thank you Dr. K! read more
