Reportability/Histology--Heme & Lymphoid Neoplasms: Is a physician statement that a patient has a malignant histiocytic disorder best described as Erdheim-Chester disease reportable? If reportable, should histology be coded to 9751/3? See Discussion.
Casefinding--Heme & Lymphoid Neoplasms: Is the 2010 casefinding code of 289.6 (Familial Polycythemia) addressed anywhere in the Hematopoietic Database? See Discussion.
Surgery of Primary Site/Scope Regional LN Surgery--Breast: How are these fields coded for breast cases diagnosed 2011 and later when the patient has a simple mastectomy with removal of seven sentinel lymph nodes? See Discussion.
MP/H Rules/Histology--Head & Neck: Please clarify rule H3. The first statement is "Do not code terms that do not appear in the histology description". The second statement is "Do not code...unless the words...appear in the final diagnosis"
One of our pathology labs frequently will state "keratinizing squamous cell" in the microscopic description (histologic description), but only state "squamous cell carcinoma" in the final diagnosis. May we code from the histologic description if it's not in the final diagnosis?
Reportability--Melanoma: Please explain how a CTR is to interpret the guideline in the MP/H rules (Cutaneous Melanoma): Evolving melanoma (borderline evolving melanoma): Evolving melanoma are tumors of uncertain biologic behavior. Histological changes of borderline evolving melanoma are too subtle for a definitive diagnosis of melanoma in situ. Is this to mean that evolving melanoma in situ is not reportable? Or should we follow the guidelines in SEER Question 20130022 that states the reportability terms for melanoma and melanoma in situ.
Histology--Heme & Lymphoid Neoplasms: Is there an inconsistency between the histologies listed as deleted in the ICD-O-3.2 Implementation Guidelines and the obsolete histologies in the Hematopoietic and Lymphoid Neoplasms Database (Heme DB)? See Discussion.
