ICD-O-3 Update

CDC is following the NAACCR Guidelines for ICD-O-3 Update Implementation (published 12/2015). It has now been determined that the new reportable histology codes originally intended for implementation with 2015 diagnoses will continue to be postponed and will NOT be implemented for 2016 diagnoses.

In 2014 and 2015, SEER added new reportable histology codes to their Program and Coding Manual. These terms had not been included in any IDC-O-3 errata or implementation guide and therefore were not addressed throughout the cancer surveillance community.

CDC has reviewed the terms and made the following decisions:

1. Non-invasive mucinous cystic neoplasm of the pancreas with high-grade dysplasia replaces mucinous cystadenocarcinoma, non-invasive (8470/2) and is REPORTABLE.
2. Solid pseudopapillary neoplasm of the pancreas (845/3) is synonymous with solid pseudopapillary carcinoma (C25._) and is REPORTABLE.
3. Based on expert pathologist consultation, metastases have been reported in some CPEN cases. With all other pancreatic endocrine tumors now considered malignant, CPEN will also be considered malignant, until proven otherwise. Most CPEN cases are non-functioning and are REPORTABLE as 8150/3, unless the tumor is specified as a neuroendocrine tumor, grade 1 (assign code 8240/3) or neuroendocrine tumor, grade 2 (assign code 8249/3).
4. Laryngeal intraepithelial neoplasia, grade III (LINIII) (8077/2) (C320-C329) is REPORTABLE.
5. Squamous intraepithelial neoplasia, grade III (SINIII) (8077/2), except Cervix and Skin IS REPORTABLE.
6. Mature teratoma of the testes in adults is malignant and reportable 9080/3, but continues to be non-reportable in prepubescent children (9080/0). The following provides additional guidance:

• Adult is defined as post-puberty
• Pubescence can take place over a number of years
• Do not rely solely on age to indicate pre- or post-puberty status. Review all information (physical, history, etc.) for documentation of pubertal status. When testicular teratomas occur in adult males, pubescent status is likely to be stated in the medical record because it is an important factor of the diagnosis.
• Do not report if unknown whether patient is pre- or post-pubescence. When testicular teratoma occurs in a male and there is no mention of pubescence, it is likely that the patient is a child, or pre-pubescent, and the tumor is benign.

VCR strongly recommends adding these to your ICD-O-3 Manual or purchase the ICD-O-3 Manual, First Revision from the WHO.
