On Oct. 1, 2015, physicians were required to start reporting patient diagnoses and submitting claims using the ICD-10 code set. Physician practices, hospitals, Medicare, Medicaid, private payers, and clearinghouses are all required to use this code set.

Failure to use the new code set will result in significant financial disruption because, after Oct. 1, 2015, claims filed using ICD-9 after will be denied as unprocessable. 

CMS announced that for 12 months following the Oct. 1, 2015, implementation deadline, Medicare claims will not be denied if providers use the wrong ICD-10 code, as long as the code is in the right category. Learn more about CMS' leniency policy.
