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 are lists of diagnosis and procedure codes commonly used for encounters with patients with epilepsy. 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 other conditions that may be causative or affecting 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: www.cdc.gov/nchs/data/icd9/icdguide09.pdf.

For ICD-9-CM (diagnosis codes) note that most require a determination of whether or not the patient is intractable and we now have several synonyms for intractable listed in the index portion of ICD-9-CM. These include:

The CPT (procedure codes) indicated are for the technical component of the charge. These should be followed by -26 for billing the professional component.
