What is New Mexico Bariatric Institute?
New Mexico Bariatric Institute is a physician-led practice at 2100 S. Triviz, Suite G, in Las Cruces, New Mexico. Its main work is bariatric surgery, and it offers medical weight loss care alongside it. The practice was called Memorial Weight Loss Center until a name change in January 2024. Its physicians, staff and location stayed the same.
The prescribing providers are Fermin Fontan, MD, FACS, FASMBS, a board-certified general surgeon; Theresa Jackson, MD; Melissa Livingston, DNP, FNP-BC; Jimmie Hauser, FNP-BC; and Stephanie Giambelluca, CNP, AGPCNP-BC. Medical weight loss may include an evaluation, nutrition and lifestyle support, and prescription weight loss medications when appropriate. Surgical options are sleeve gastrectomy, gastric bypass, SADI-S, revisional bariatric surgery, and gastric band repair or removal. Operations are performed at Memorial Medical Center. The staff is bilingual, and Dr. Fontan speaks English and Spanish.
The office is open Monday through Friday, 8 am to 5 pm. The phone number is 575.556.1849. It has a Google rating of 4.6 from 187 reviews. The clinic does not list hormone therapy, peptide therapy or longevity services.
What does it cost?
It does not publish prices for medical weight loss or surgery, and it does not state a consultation fee. Nothing says whether medication is included in any program fee. On insurance, it puts it this way. In its own words: "Insurance coverage for bariatric surgery and medical weight loss services varies by plan." It does not say which plans it accepts or whether it takes cash pay only.
What should you ask before you book?
Ask who will write your prescription, and whether it will be one of the physicians or one of the nurse practitioners. Ask which medication would be used, if any. The practice supports patients who take GLP-1 medicines, but it does not name one. Ask whether that drug is brand-name or compounded. Ask whether the monthly or program fee includes the medication, and what follow-up visits and lab work cost on their own.
If you are considering surgery, ask whether the clinic accepts your insurance and what you would owe out of pocket. Call the number on your insurance card and ask whether your plan covers weight loss surgery when it is medically necessary. Ask who performs the operation and what follow-up costs after it. Ask whether visits can be done by video, since the clinic does not say whether telehealth is offered. Finally, ask how to cancel a program and whether there is a notice period.
Who is it a good fit for?
This is a good fit if you live near Las Cruces, want a practice led by a surgeon that offers both surgical and nonsurgical weight loss care, and are willing to get prices in writing before you commit. If you need hormone, peptide or longevity care, this clinic does not list those services, so it is not a match for that need.
