U.S. Moves to ICD-10 Coding System

October 2015

On Thursday of this week, physicians and other providers across the country switched from ICD-9 to ICD-10 coding.  Starting October 1st, any claim submitted using ICD-9 will be rejected by Medicare and other payers.

To help ATS members understand the new ICD-10 coding system, the ATS held a series of webinars to educate ATS members on ICD-10 coding for pulmonary, critical and sleep medicine.  Recordings of the webinars are available on the ATS website.

CMS has also provided several resources to help physicians and their staffs with the new ICD-10 system.  The ICD10 ombusman email address is ICD10_Ombudsman@cms.hhs.gov. Physicians can also contact their Medicare Administrative Contractor (MAC) or monitor their MAC's website for information on problems with ICD-10 including:

Selected commercial payers have also created their own ICD-10 resources, including UnitedHealth Group (ICD10questions@uhc.com) and  Humana (ICD10Inquiries@humana.com).  For other commercial payers, please check payer website for additional resources.

Questions can also be submitted to the ATS at codingquestions@thoracic.org.
