What is Premier Endocrinology?
Premier Endocrinology is an endocrinology practice, so its main work is treating hormone, thyroid, diabetes and metabolic conditions. It has offices in St. Cloud and Kissimmee, Florida, and its phone number is 407-593-2910. The practice mentions three Florida locations, but it names two offices, one in each of those towns.
The clinicians it names are Theresa Fynn, MD, who practices in St. Cloud, and Kwame Ntim, MD, who practices in Kissimmee. Also listed are Mustafa Kinaan, MD, Dionardo Medina Encarnacion, MD, and Yolanda Palmero, ARNP. The practice lists eight services: osteoporosis, diabetes, low testosterone and PCOS, adrenal disorders, obesity, pituitary disorders, thyroid diseases and lipid disorders. Its material on low testosterone and obesity describes hormone replacement therapy as one possible part of a treatment plan. The PCOS material names birth control pills, progestin therapy and insulin-improving medications. The diabetes material mentions insulin pumps and continuous glucose monitors. In its own words: "They offer the most advanced care available, including the use of insulin pumps, continuous glucose monitors, modern prescription medication and hormone replacement therapy, and downloadable glucose meters, to name a few."
This listing is for its Kissimmee office at 505 W Oak St Ste 102.
What does it cost?
It does not publish prices, a consultation fee or membership terms. It does not say whether medication is included in any charge. It also does not mention financing or HSA payment.
The practice accepts insurance, and it says so plainly: "Many major insurance plans are accepted, please call our office to verify your plan's coverage." The networks it lists include Aetna, Blue Cross Blue Shield, Cigna, Humana, Medicare, Medicaid and United Health Care, among others. A copay is due at each visit. The office takes cash, check, Visa, Master and Discover cards.
What should you ask before you book?
Ask which clinician writes and renews any prescription, and who handles your follow-up visits. If you plan to pay without insurance, ask for the full price of a first visit and whether it includes labs. Ask what follow-up visits and lab work cost.
If a medication is prescribed, ask whether it is brand name or compounded, and what it costs each month. If you are considering the obesity care, ask whether a GLP-1 weight loss medication is prescribed at this practice, since the practice does not say. Ask whether any membership or recurring charge applies, and how to cancel it. Also ask whether telehealth visits are available and what the office hours are at each location, because neither is listed.
Who is it a good fit for?
This is a good fit if you have one of the listed insurance plans and want an endocrinologist to look into a hormone, thyroid, diabetes or weight concern, with the visit billed through your insurance. It is a weaker fit if you want a cash-pay weight loss program with a posted monthly price, since none is published.
