For services provided on or after October 1, 2015, Medicare requires that healthcare providers must use valid ICD-10 Codes. The transition to ICD-10 is required for everyone covered by the Health Insurance Portability Accountability Act (HIPAA). Please note, the change to ICD-10 does not affect CPT coding for outpatient procedures and physician services. The Commission encourages healthcare providers and payers to engage in a dialogue as to implementation timeframes. For additional details and assistance, please visit:
