Codes for the histologic type of the tumor being reported using ICD-O-3. NAACCR adopted ICD-O-3 as the standard coding system for tumors diagnosed in 2001 and later, and recommended that prior tumors be converted from ICD-O-2. Effective with 2010 diagnoses, this item also includes histology codes as per the 2008 WHO Hematopoietic/Lymphoid publication 39, which are listed on pages 3-5 of the NAACCR 2010 Implementation Guidelines.
