Dr. Marc Lyle Kozam, MD

I had a very positive experience with Dr. Kozam. I was able to get all appointments within two weeks of calling. In each appointment, he took the time to explain the process or discuss the outcome. He was friendly, professional and timely every time. The whole experience was the best I could have expected and I highly recommend Dr. Kozam.

Funny that some other reviewer said why so much hate. Because Dr Kozam is the WORST DOCTOR EVER. Arrogant, impatient, smug, and just a general hack. There is no conspiracy regarding this guy. He is the worst. All the bad reviews are true (and there are many).

Not competent and talks to patients like dogs. This is the only doctor I have seen doing a diagnosis based on one symptom.

Dr Kozam was not very professional about the correct billing. He charged my insurance for an office visit that he did not perform. He just gave me results from the procedure and billed me for an office visit that he could have given me the results post op in recovery as my wife was with me or over the phone. No need for an additional appointment just to say no polyps, everything is negative and you don’t need to come back for ten years. That should hav been done over the phone or in recovery. He charged me an additional office visit for a ten minute meeting, which really should have been done over the phone or via email.

I tried to speak with Gina on several dates about resubmitting to my insurance with the correct codes so the insurance could reimburse him for the results of the procedure as my insurance informed me that they will pay at 100% as this is considered preventative and Gina just sent my account into collections. I found this office to be extremely unprofessional… and I do not recommend this practice. I would use and will use another office in the future.

I've been a patient since 2013. Dr. Kozman has been patient, friendly bedside manner and explains in detail the diagnosis and recommendations for after care. He has even referred me to another physician for further treatment.

He is known well at Rockville Surgery Center. He does follow-up appointments very well. Medical skills are excellent.

Easy to make an appointment with dr Kozam, my experience in his office was excellent from the beginning, the dr staff really friendly and he helped me to understand my problem and to take care of it. Thanks dr Kozam my life is way better now.

I was having some difficulties so I consulted with Dr. Kozam and he performed an endoscopy. From the consultation to the follow up, he was excellent. Very informative, kind & appropriate bedside manner, no issues with the procedure or the Rockville surgery center or staff. It's very apparent he has tons of experience and knowledge. Scheduling was easy and the office staff very helpful, friendly and informative. I would highly recommend Dr. Kozam!
