Part C coverage information
Understand how a coverage decision is handled or request a prior authorization.
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 policy types and descriptions.
Visit CMS.gov for more information on the CMS NCD.
Organization determination (coverage decision) for Part C
A coverage decision is a decision we make about your benefits and coverage or about the amount we will pay for your medical services or drugs. In some cases, we might decide a service or drug is not covered or is no longer covered by Medicare for you. If you disagree with this coverage decision, you can make an appeal. You, your physician, or your representative may make a written standard appeal request or oral or written expedited appeal request. When we give you our decision, we will use the standard deadlines unless we have agreed to use the expedited deadlines. A standard coverage decision means we will give you an answer within 7 days after we receive your doctor's statement. An expedited coverage decision means we will answer within 72 hours after we receive your doctor's statement. If the coverage decision is for a Part B drug (covered by your medical insurance not your drug coverage) and expedited, we will make a decision within 24 hours of us receiving the request, and if standard, we will make a decision within 72 hours of us receiving the request.
