Office of Workers' Compensation Programs (OWCP)
On October 1, 2015, on a schedule aligned with the Centers for Medicare & Medicaid Services (CMS), the Office of Workers' Compensation Programs (OWCP) implemented the International Classification of Diseases, 10th Edition, Clinical Modification/Procedure Coding System (ICD-10-CM/PCS) code set. For services provided on, or after, October 1, 2015, OWCP will require all providers to use only the ICD-10 code sets. For services provided prior to October 1, 2015, only ICD-9 codes will be accepted. OWCP will not convert current claimant ICD-9 accepted conditions to ICD-10 codes. Claimants will only be given ICD-10 codes for accepted conditions filed on or after 10/1/2015. Providers should submit bills with an ICD-10 diagnosis code(s) that is reflective of the condition(s) being treated.
