ICD-10: Quick Facts and Resource Reminders

Jul. 21, 2015

The U.S. Department of Health and Human Services (HHS) published a final ruling in early August 2014, confirming an Oct. 1, 2015, mandated transition to ICD-10. As of this compliance deadline, all Health Insurance Portability and Accountability Act (HIPAA) covered entities must use ICD-10 on claims and other health care transactions.

  • ICD-10-CM will replace ICD-9-CM for diagnosis coding in all health care settings. ICD-10-PCS will replace ICD-9-CM for inpatient procedure coding.
  • Outpatient and professional ICD-10 coding is based on date of service; inpatient institutional ICD-10 coding is based on date of discharge.
  • Outpatient and professional claims will need to be split if services dates span the compliance date.
  • Use of other codes, such as Current Procedural Terminology (CPT®), HCPCS and Revenue Codes will not be impacted by the transition to ICD-10.

There are many industry resources available to assist providers with making the transition to ICD-10. The Centers for Medicare & Medicaid Services (CMS) offers training modules for Continuing Education Units (CEUs) and helpful resources for small and medium provider practices, such as the Road to 10  and new Quick Start Guide .
