Part C coverage information
Understanding your health plan is very important. Review the information below to learn about your plan’s coverage and administration to make the best use of your benefits. To find out more about the benefits in your plan, simply log in at amerihealth.com/login.
Centers for Medicare and Medicaid Services (CMS) National Coverage Determinations (NCD)
The Company primarily relies on national coverage determinations (NCDs), local coverage determinations (LCDs), and other coverage guidance from the Centers for Medicare and Medicaid Services (CMS) and local Medicare contractors in the development of its Medicare Advantage medical policies. When Medicare coverage criteria are not fully established in applicable Medicare statutes, regulations, NCDs or LCDs, CMS allows Medicare Advantage plans to develop publicly accessible internal coverage criteria. The internal coverage criteria are based on current evidence in widely used treatment guidelines or clinical literature. Current, widely used treatment guidelines are those developed by organizations representing clinical medical specialties, and refers to guidelines for the treatment of specific diseases or conditions. Acceptable clinical literature includes large, randomized controlled trials or prospective cohort studies with clear results, published in a peer-reviewed journal, and specifically designed to answer the relevant clinical question, or large systematic reviews or meta-analyses summarizing the literature of the specific clinical question. For more information please see policies and guidelines.
Visit CMS.gov for more information on the CMS NCD.
