ICD-10 Ombudsman and ICD-10 Coordination Center (ICC)

Welcome to the ICD-10 Coordination Center (ICC) Page.

For the first few months of the ICD-10 implementation, the ICD-10 Coordination Center served as a one-stop shop for provider questions.  Given the success of the implementation, the ICC is now closed.  

Many resources remain to help providers with ICD-10 questions.  We have a step-by-step resource list https://www.cms.gov/Medicare/Coding/ICD10/ICD-10-Provider-Contact-Table.pdf to help you locate important contacts quickly.  

For questions about coding:

The Centers for Medicare & Medicaid Services does not provide specific coding guidance, listed below are several resources that may be able to assist you:

The ICD-10 code lookup tool: https://www.cms.gov/medicare-coverage-database/staticpages/icd-10-code-lookup.aspx 

For specific coding questions: Specific coding questions should be submitted to the American Hospital Association (the official US clearinghouse on medical coding) via http://www.codingclinicadvisor.com/

AHIMA is now also providing coding advice for a fee through their Code Check service. You can learn more information at this link: http://www.ahima.org/topics/codecheck
