Description
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 publication39, which are listed on pages 3-5 of the NAACCR 2010 Implementation Guidelines. http://www.naaccr.org/StandardsandRegistryOperations/ImplementationGuidelines.aspx.

Note: See Histology (92-00) ICD-O-2 [420] for ICD-O-2 codes. 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. http://www.naaccr.org/LinkClick.aspx?fileticket=U-3o31G2Lik%3d&tabid=126&mid=466

Clarification of Required Status
This data item is required by all standard-setting organizations for tumors diagnosed on or after January 1, 2001, and recommended (by conversion from ICD-O-2 codes when conversion algorithms and tables are available) for tumors diagnosed before 2001.

When the histologic type is coded according to ICD-O-3, the histology code must be reported in Histologic Type ICD-O-3 [522], with behavior coded in Behavior Code ICD-O-3 [523].

For information on required status for related data items for histologic type and behavior when coded according to ICD-O-2, see Histology (92-00) ICD-O-2 [420] and Behavior (92-00) ICD-O-2 [430].
