Revision History

05/1998 - Added two new covered uses for these studies: acute leukemia (lymphoid, myeloid, and unclassified) and myelodysplasia. Effective date 07/16/1998. (TN 105)

03/2013 - CMS translated the information for this policy from ICD-9-CM/PCS to ICD-10-CM/PCS according to HIPAA standard medical data code set requirements and updated any necessary and related coding infrastructure. These updates do not expand, restrict, or alter existing coverage policy. Implementation date: 10/07/2013 Effective date: 10/1/2015. (TN 1199) (TN 1199) (CR 8197)

08/2016 - This change request (CR) is the 9th maintenance update of ICD-10 conversions and other coding updates specific to national coverage determinations (NCDs). The majority of the NCDs included are a result of feedback received from previous ICD-10 NCD CR7818, CR8109, CR8197, CR8691, CR9087, CR9252, CR9540, and CR9631. Some are the result of revisions required to other NCD-related CRs released separately.
Edits to ICD-10 and other coding updates specific to NCDs will be included in subsequent, quarterly releases as needed. No policy-related changes are included with these updates. Any policy-related changes to NCDs continue to be implemented via the current, long-standing NCD process. (TN 1708) (CR9751)
