ICD-10

ALERT!  ICD-9 codes can no longer be reported after October 1, 2015.

The International Classification of Diseases, 10th Edition, Clinical Modification/Procedure Coding System (ICD-10 CM/PCS) will fully replace the International Classification of Diseases, 9th Edition, Clinical Modification/Procedure Coding System (ICD-9) on October 1, 2015. Providers may no longer bill with ICD-9 codes after this date. Therefore, it is important to take the time to educate oneself about ICD-10 and determine what impact it will have on your practice. ASCO staff has provided resources to get you ready for the transition. Any questions regarding ICD-10 can be sent to ASCO staff at billingandcoding@asco.org.
