Special Needs Plans (SNPs) can only accept people who fit the specific special needs category they are serving. For example, if you have diabetes, congestive heart failure, or HIV/AIDS you might be able to join a SNP for people with your condition.  Additionally, people who have both Medicare and Medicaid can join a SNP specifically for people who are dual-eligibles (have both Medicare and Medicaid). You must also live in the SNPs service area.

Unlike other types of Medicare Advantage Plans (HMOs and PPOs), Special Needs Plans may enroll people with End-Stage Renal Disease (ESRD) if they choose to serve that population.
