Maura, we apologize you feel as though you were not heard in your office visit. We understand the high cost medications can have and the medication you were prescribed was the best choice for your care. Dr Lewis and our team expedited an appeal to your insurance company to help lower the cost and while an appeal doesn't always work we were successful in doing so in your case. If you have questions, please feel free to contact our office at 303-788-8888. Thank You, South Denver Gastroenterology
