Relapsing-remitting multiple sclerosis

This code represents the most common form of multiple sclerosis, characterized by clearly defined attacks (relapses) of new or worsening neurological symptoms, followed by periods of partial or complete recovery (remissions). During remissions, symptoms may disappear or remain mild, and there is no apparent progression of the disease.

This code is appropriate when documentation explicitly states a diagnosis of relapsing-remitting multiple sclerosis. It should be used for patients experiencing active relapses, as well as those in remission from this specific MS subtype. Documentation should clearly distinguish this form from other MS types.

• Do not use this code for other forms of MS, such as primary progressive or secondary progressive MS, which have distinct codes.
• Ensure documentation specifies "relapsing-remitting" to support the use of this highly specific code.
• Consider sequencing this code as the primary diagnosis when it is the reason for the encounter, especially during relapse management.
