At a meeting on September 14, 2011, the ICD-9-CM Coordination and Maintenance (C&M) Committee implemented a partial freeze of the ICD-9-CM and ICD-10 (ICD-10-CM and ICD-10-PCS) codes prior to the implementation of ICD-10, which would end one year after the implementation of ICD-10. The implementation of ICD-10 was delayed from October 1, 2014, to October 1, 2015, by final rule CMS-0043-F issued on July 31, 2014.
