Wellpoint STAR+PLUS MMP (Medicare-Medicaid Plan)

Members have access to most national pharmacy chains and many independent retail pharmacies that are contracted with us. Members may obtain their medications at any network pharmacy.

Clinical pharmacy policies

Drug coverage policies are based on medical necessity considerations subject to applicable benefits. These policies assist with medical necessity coverage decisions, may include state-specific guidance regarding coverage and do not constitute medical advice. Benefit determination is based on the applicable contract language and/or state requirements.

These policies are not a guarantee of coverage. Contract language or state requirements will prevail when there are conflicts with any medication coverage policy. In all cases, Medicaid contracts or CMS requirements supersede policy criteria.
