Diagnostic confirmation--Heme and Lymphoid Neoplasms--Lymphoma: Is Diagnostic Confirmation "5" for Hematopoietic Neoplasms appropriate for this case? There appears to be no conclusive histologic diagnosis (Neoplasm, suggestive of lymphoma) and only the IHC/flow cytometry issued a conclusive diagnosis. See Discussion.

Reportability: Is ASIN-H (high-grade anal squamous intraepithelial neoplasia) equivalent to anal intraepithelial neoplasia, III (AIN III)?

Histology--Head & Neck:  Why is 8070 not listed as a valid histology for ill-defined sites as squamous cell carcinoma arises in the head and neck sites. See Discussion.

Reportability/Histology--Vulva: Is Extramammary Paget neoplasm (intraepithelial glandular neoplasm) reportable? See Discussion.
 

Tumor Size--Clinical--Breast: Does information from any type of biopsy take precedence over an imaging report? See Discussion.

Solid Tumor Rules (2018)/Histology--Brain and CNS:  How are histology and primary site coded when a resection of a spine, designated intramedullary lesion, shows primary intramedullary melanocytoma? See Discussion.

Solid Tumor Rules (2018)/Multiple primaries--Colon: Solid Tumor Rules 2018, Colon Rule M7, bullet 3 indicates that (if neither bullet 1 or 2 apply) a new tumor at the anastomotic site must be stated to arise in the mucosa (confirmed in SINQ 20190096) to qualify as a new primary. However, there is often no clear statement of tumor arising from or involving mucosa (unless the new tumor is limited to the mucosa) noted by pathologists in our region. Do any of the following examples imply a new tumor arising in mucosa per Rule M7, bullet 3?  See Discussion.
 

Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned for a patient diagnosed with myelodysplastic syndrome (MDS) with ring sideroblasts in 2005, and stated to have progressed to high risk disease/early evolving acute myeloid leukemia (AML) in 09/2019? See Discussion.

Race: How should race information from linkages be incorporated into the coding of Race? See Discussion.

 

Solid Tumor Rules (2018)/Histology--Head & Neck: How is histology coded for a glossotonsillar sulcus tumor with both squamous cell carcinoma and mucoepidermoid carcinoma? See Discussion.
