What is a Medicare Special Needs Plan?

Understanding Special Needs Plans

A Special Needs Plan (SNP) is one kind of Medicare Advantage Plan. These plans deliver tailored health care and support to individuals dealing with serious, long-term illnesses. They also serve people with certain health care needs and people who have both Medicare and Medicaid.

SNPs are designed to help manage complex health situations. They include care coordination services to guide you through your care. Each plan shapes its benefits, its choice of doctors and its drug list around the group it serves.

The Three Types of SNPs

There are three main categories of these plans. The first is the Dual Eligible SNP, or D-SNP. This type is for people who have both Medicare and Medicaid.

The second type is the Chronic Condition SNP, or C-SNP. A C-SNP can limit who joins to people with one chronic condition or a group of related conditions. The third is the Institutional SNP, or I-SNP, which serves people who live in facilities.

Eligibility Requirements

To join an SNP, you need Medicare Part A and Part B. You also need to meet the requirements for one of the three SNP types.

Availability varies by location. The availability of various SNP categories fluctuates annually across different regions of the nation. Insurance companies decide where they will do business, so these plans may not be available everywhere in the U.S.

How Doctors and Drugs Work

All SNPs must provide Medicare drug coverage, known as Part D. However, the specific drugs covered depend on the plan's formulary. You should check if your preferred medications are on the list before joining.

Some SNPs require you to get your care from doctors and facilities in the plan’s network. Emergency care, urgent care while you are away from home, and dialysis while you are away from home are the exceptions. Some plans offer out-of-network coverage, but you will usually pay more for these services.

Costs and Extra Benefits

SNPs include the identical Medicare Part A and Part B benefits found in every Medicare Advantage Plan. They may also add extra benefits for the group they serve. For instance, an SNP might pay for extended hospital stays if you are dealing with a serious illness.

Some plans charge a monthly premium in addition to the Part B premium. If you have both Medicare and Medicaid, most of your costs are usually covered. Contact your Medicaid office for more information about your specific costs.

Staying Enrolled

To stay in an SNP, you have to keep meeting its requirements. If you lose your plan because you no longer meet them, you may get a Special Enrollment Period. This allows you to join another plan.
