Attention: Medicaid Patients

Urgent Notification

August 28, 2024

We are reaching out to inform you of an important change regarding your healthcare coverage at Northeast Endocrinology. Effective December 1, 2024, our practice will no longer be accepting Medicaid insurance.

If you are currently covered by Medicaid, we strongly encourage you to contact your insurance carrier as soon as possible to obtain a list of in-network providers who can continue your care. It is essential to ensure that you have uninterrupted access to the medical services you need.

If you would like to have your medical records forwarded to your new provider or would like to obtain a copy for your personal records, a signed Medical Release form will be required. This document can be easily downloaded from our website at www.neendocrinology.com.

Please complete and return the signed form to our office, and we will promptly process your request.

We understand that this change may be inconvenient, and we are committed to supporting you during this transition. If you have any questions or need assistance, please do not hesitate to contact our office via the patient portal, or you may reach the office at 210-650-3360.

Thank you for allowing us to be a part of your healthcare journey.

“Dr. Guerrero is wonderful! He is very understanding and works with you to get in the best health. He listens and is genuinely caring of his patients concerns.”
“Responsive staff members, great online portal. Convenient location and I’ve been seeing Dr Khowaja for the past 2 years and my experience with him has been outstanding.”
“Excellent service!!! The medical staff was super nice and Dr. Martha was incredibly accurate and knowledgeable, she gave sharp and detailed information, I highly recommend her!!!”
“This is the most efficient, timely, well run, best staffed medical office I have ever been seen at. I’m in and out in 30min, every time. Dr Najera is an incredible doctor I absolutely love him and with his help I’ve lost over a hundred pounds in a year and a half, which has been life changing for me. The staff is so friendly my phone calls are always answered or returned promptly. Other practices it can be like pulling teeth to get prescriptions sent in or refilled but at Northeast Endocrinology I get my medication questions answered and refills called in the same day I inquire about it. I can’t overstate how impressed I am with this establishment and Dr. Najera.”
“I normally do not take the time to give a review but I will for Dr. Guerrero because he does take the time to listen and go over anything that is bothering you. So, if you are looking for a caring, well mannered, informative and 5 Star Personality, make an appointment with Dr. Guerrero. He most likely will give you “homework” but you’ll be better for it. Thanks,”

“Being a type 1 diabetic with thyroid issues I have seen many endocrinologists in the San Antonio area throughout my years and Dr Guerrero is by far the absolute best. He takes time to go over any and all questions without feeling rushed or judged. He is up to date and knows how to use, fine tune & tweak all the updated diabetic technology & tools so I can use it to my advantage. On top of this, his staff is exceptionally nice and caring. I am thrilled to have finally found a doctor who can care for a disease I have revolved my life around and is there to really help me manage it and be my absolute best. I would recommend Dr Guerrero to anyone in need of an endocrinologist.”
“Dr. Ameer Ali Khowaja has been wonderful! He has gone above and beyond in managing my resolving subacute thyroiditis. On several occasions, he diligently followed up my laboratory test results and adjusted my levothyroxine dosage accordingly. He answered all of my questions and allayed my fear of going off the levothyroxine entirely. He is very dedicated and caring!”
“Dr. Bilbatua and the NE Endocrinology office in San Antonio have been exceptional care givers! Collaborating with Dr. Bilbatua on enhancing my diabetes management has been truly rewarding, and I deeply appreciate her attentive approach. The office staff is consistently friendly and incredibly accommodating. I look forward to continuing as a patient for the long term.”

“There are not enough words to describe the care I had been provided from Dr Omar Najera since 2016. He had under control my Graves’s disease, diabetes and other health issues that have been threatening my life for decades. With his knowledge, professionalism, compassion. dedication, persistent work with pharmaceutical companies, battling health insurance companies to provided me with the right medication every single month for years. His compassion and dedication is not seen in many physician. He is on top of advance and new treatments to provide the best care available for his patients. His attention of every detail while communicating with patients is second to none. His humility, simple way to explain complex medical approaches make him an over the top physician. His manners speaks of how respectful he always treat his patients. My experience as his patients pass way far my expectations. Dr. Najera is the doctor I’m lucky to have. For that and many more…I’m eternally grateful.”
