The International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM), is based on the official version of the World Health Organization's Ninth Revision.

ICD-9 codes are to be used on Medicare professional (Part B and DME) claims for dates of service before October 1, 2015. When submitting a data span, the "from" date (not the "to" date) determines whether an ICD-9 or ICD-10 diagnosis code should be on the claim. For claims with "from" dates before October 1, 2015, submit an ICD-9 diagnosis code.
