Prescription Drug Plans

Williamson County Medicare beneficiaries who are interested in a private Medicare policy may choose among the following types of plans, depending on their needs and circumstances:

Plan Type	Description
HMO	HMO enrollees typically receive services through in-network providers and must obtain referrals for visits to specialists. However, most plans permit out-of-network care in emergencies or out-of-area dialysis. HMO plans often include prescription drug coverage.
PPO	Members of PPO plans can typically go in or out of network for care, including hospitalization, although visits to non-network providers may cost considerably more. Referrals are usually not needed for visits to specialists, and many PPO plans include prescription drug coverage.
PFFS	Private fee-for-service plans determine how much a doctor or facility will be paid for services, and members may seek care from any in or out-of-network provider that agrees to the plan's terms. Some PFFS plans include prescription drug coverage. Otherwise, members may seek coverage for medications through standalone Medicare drug plans, which are also known as Part D plans.
SNP	Special Needs Plans are designed for individuals with specific conditions or medical characteristics. Benefits such as providers and drug formularies are tailored to members' unique needs, and most care is provided by in-network physicians and facilities. SNPs are required to provide prescription drug coverage.
