Can Mrs. Chou enroll in a stand-alone prescription drug plan if she is in a Private Fee-for-Service (PFFS) plan?

In the context of Medicare, Mrs. Chou can indeed enroll in a stand-alone prescription drug plan (PDP) while being a member of a Private Fee-for-Service (PFFS) plan. This is because PFFS plans operate under Medicare Advantage but do not inherently include drug coverage. If the PFFS plan does not offer prescription drug coverage or if Mrs. Chou desires additional benefits, she has the flexibility to enroll in a PDP without restrictions.

It is important to note that having both a PFFS plan and a stand-alone PDP is permissible as long as Mrs. Chou meets the eligibility requirements for the PDP. Therefore, the option suggesting that she can enroll in both correctly represents the choices available to her under Medicare policies.
