EOD-Extension--Hematopoietic, NOS: If a solitary plasmacytoma originates in the right tonsil and extends to the left tonsil, vallecula and hypopharynx, is extension still coded to 10 [localized disease, solitary plasmacytoma only]?
EOD-Extension--Cervix: Should this field be coded to 11 [minimal microscopic stromal invasion] or 12 [microinvasion] when there is only a statement of "microinvasion" but no measurements describing the level of involvement given?
EOD-Extension--Corpus Uteri: What code is used to represent this field for a corpus primary (sounding 8 cm or less in length) treated with radiation prior to a hysterectomy that pathologically showed superficial myometrial invasion? Is it possible that the invasion could have been more extensive prior to the radiation treatment?
EOD-Extension--Pancreas: How do you code extension when a mass is described on exploratory laparotomy as compressing the duodenum, arising in the head of the pancreas, "extending around" the superior mesenteric vein and artery, and "encasing" the portahepatis?
EOD-Extension--Small Intestine: How do we interpret a pathology description of "extending through serosa and forming masses in the periserosal tissue" for a jejunum primary?
EOD-Extension/SEER Summary Stage 2000--Kidney/Eye: What codes are used to represent these fields for simultaneous bilateral Wilms tumor or simultaneous bilateral retinoblastoma?
EOD-Extension--Lung: How do you code extension for a lung tumor described on bronchoscopy as "obstructing the RUL and intruding into the right bronchus intermedius. Small tumor nodules distally in midline of anterior trachea wall"?
