  • Switch to a different Marketplace plan. If you switch to a new health plan that does not cover your current medications, treatments or doctor, ask for an exception to maintain temporary coverage of them to avoid interruptions in care.   
Decisions should be based on the current law and plans currently available; change can take time.

About Multiple Sclerosis

Multiple sclerosis is an unpredictable, often disabling disease of the central nervous system that disrupts the flow of information within the brain, and between the brain and body. Symptoms range from numbness and tingling to blindness and paralysis. The progress, severity and specific symptoms of MS in any one person cannot yet be predicted, but advances in research and treatment are leading to better understanding and moving us closer to a world free of MS. Most people with MS are diagnosed between the ages of 20 and 50, with at least two to three times more women than men being diagnosed with the disease. MS affects more than 2.3 million people worldwide.
