Accurate coding is an important function of neurologic practice. This section of CONTINUUM, contributed by members of the AAN Medical Economics and Management Committee, includes a table of helpful coding information related to the issue topic. The table may include diagnosis coding, Evaluation and Management (E/M) coding, procedure coding, or a combination, depending on which is most useful for the subject area of the issue.

Below is a list of diagnosis codes commonly used for encounters with patients with multiple sclerosis. This list is not all-inclusive, and reference to a full volume of the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) is recommended for helpful subterms, instructions, and coding of other conditions that may be causative or affect the presenting illness. For a full set of rules regarding diagnosis coding, see the Official ICD-9-CM Guidelines for Coding and Reporting, which may be found at
