The U.S. Department of Health and Human Services (HHS) issued a rule finalizing October 1, 2015, as the new compliance date for health care providers, health plans, and health care clearinghouses to transition to ICD-10, the tenth revision of the International Classification of Diseases.
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.
