EOD-Size of Primary Tumor: Can you code the known size of the residual tumor in a further resected specimen if the size of the tumor in a prior excisional biopsy is unknown? See discussion.
EOD-Extension--Bladder: Both papillary transitional cell ca in situ and sessile (flat) transitional cell ca in situ are diagnosed simultaneously in the bladder. We code the higher histology (8130/2). For extension, do we use the code that corresponds to the histology (01), or to the higher extension code (06)?
Histology (Pre-2007): What codes are used to represent the histology "mucinous adenocarcinoma arising in a villous adenoma" and "mucinous adenocarcinoma arising in a villous glandular polyp"? See discussion.
EOD-Lymph Nodes--Breast: Are lymph nodes described as being either "keratin positive" or "keratin positive for metastasis" to be coded as involved lymph nodes?
Scope of Regional Lymph Node Surgery: Should this field be coded to "unknown or not applicable" for all hematopoietic morphologies, brain primaries and unknown primaries?
Histology (Pre-2007)/EOD-Lymph Nodes/SEER Summary Stage 2000--Breast: What codes are used to represent these fields for a breast case with a diagnosis of ductal carcinoma in situ and a positive regional lymph node?
