Date of Diagnosis/Histology (Pre-2007)/Behavior--Melanoma: How are these fields coded when the first shave biopsy finds "what appears to be the top of a melanoma" and a subsequent shave biopsy finds "features consistent with lentigo maligna?"
Laterality/Multiple Primaries (Pre-2007)--Ovary: Are ovarian primaries with bilateral involvement always coded to laterality 4 (bilateral)? See Description.
Ambiguous Terminology/Histology (Pre-2007): How do we code histology when there is a difference between the histology mentioned on a suspicious cytology and the clinical diagnosis by the treating physician? See Description.
EOD-Size of Primary Tumor: Can size be coded from a needle bx that removes all of the invasive tumor and just leaves a "focus of in situ"? See Description.
Histology (Pre-2007)--Breast: Should the histology "non-invasive papillary carcinoma" along with the comment "solid intraductal papillary proliferation includes cytologically atypical cells with scattered mitotic figures" be coded to 8503/2 [intraductal papillary carcinoma] or 8050/2 [papillary carcinoma in situ]?
EOD-Systemic Symptoms at Diagnosis--Lymphoma: Would the description, "three days of typical cold symptoms including congestion, sneezing, chills and advanced difficulty breathing and some fever" qualify as B-Symptoms?
Reason No Cancer-Directed Surgery--Hematopoietic, NOS: Is this field always coded to 1 [not performed, not part of first course] for leukemias & other hematopoietic diseases?
EOD-Size of Primary Tumor--Breast: How do we code this field when there is a difference between the size of the tumor mentioned in the gross (i.e., macroscopic description) and the comment sections of a pathology report? See Description.
EOD-Extension--Head & Neck: Is this field coded 10 [Invasive tumor confined to one of the following subsites: interior wall, one lateral wall, posterior wall] or 30 [Localized, NOS] for tonsillar primary when there is no mention of involvement of surrounding structures? See Description.
