EOD-Extension--Lung: For a left upper lobe lung tumor that extends across the fissure into the left lower lobe, should this field be coded to 10 [Tumor confined to one lung] or 77 [Separate tumor nodules in different lobe]?
For cases diagnosed 1998-2003: Assign EOD extension code 10 [Tumor confined to one lung]. EOD extension code 10 applies to a single tumor within one lung, even one that crosses over a fissure into another lobe. EOD extension code 10 is not correct if the tumor extends to the pleura, or if there is atelectasis, obstructive pneumonitis or malignant pleural effusion. Code 77 is incorrect because that is a separate tumor nodule in a different lobe.
EOD-Extension--Colon: How is this field coded for an appendical primary when the appendix has ruptured and intrapentoneal fluid is positive?
For cases diagnosed 1998-2003: Code EOD extension as 85 [Metastasis]. Positive intraperitoneal fluid is equivalent to distant metastasis (implantation) for colon, including appendix, primaries.
EOD-Lymph Nodes--Lung: Are positive "neck nodes" coded to 7 [Distant lymph nodes, other than above (including cervical lymph nodes)] in this field because we do not have a specific lymph node chain named or are they coded to 6 [Contra lateral hilar or mediastinal (incl. bilateral); supraclavicular (transverse cervical), ipsilateral or contralateral; scalene, ipsilateral or contralateral] because this code represents the lowest possible code for involved neck nodes?
For cases diagnosed 1998-2003: Code EOD-Lymph Nodes as 7 [Distant lymph nodes, other than above (incl. cervical neck nodes)]. Lymph nodes in the "neck" are distant, rather than regional, for lung.
EOD-Extension--Corpus Uteri: How is this field coded for a stage III A endometrial primary with positive pelvic washings, involvement of the omental serosa, and negative lymph nodes?
For cases diagnosed 1998-2003: Code EOD-extension as 85 [Metastasis]. According to our TNM consultant, Omental metastasis is M1, Stage IVB [EOD 85].
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.
Site is stated to be "left tonsil" and was coded to site C099. "The lesion is admixed in tonsillar tissue." No surrounding structures are stated to be involved. Is it logical to assume that since code C099 includes the palantine tonsils and the palatine tonsils are on the lateral wall and since no other areas are stated to be involved that extension code 10 [confined to one lateral wall] would be more appropriate than code 30 [localized NOS]?
For cases diagnosed 1998-2003: Code EOD-extension for the case example to 10 [Invasive tumor confined to one of the following subsites: anterior wall, one lateral wall, posterior wall]. The tonsil lies in a pocket on the wall (tonsillar fossa), so you know it is confined to the wall.
EOD-Extension--Corpus uteri: How should EOD extension be coded when the pathology report shows adenocarcinoma arising in the endometrium with the statement "no invasive carcinoma identified?"
For cases diagnosed 1998-2003: Code endometrial cancer with no invasion to EOD extension code 11 [Confined to endometrium (stroma)]. "No invasion" most likely means no invasion of the myometrium.
EOD-Extension--Kidney: How would this field be coded when the pathology report shows a 20 mm surface neoplasm with smaller yellow metastatic implants on the surface of the kidney?"
For cases diagnosed 1998-2003: Code extension as 10 [Invasive cancer confined to kidney cortex]. Tumor involves the cortical surface of the kidney with separate surface lesions, but does not extend beyond cortex.
EOD-Size of Primary Tumor--Breast: How would this field be coded, using the revised and expanded breast code, for a lesion described as "1.3 cm infiltrating ductal carcinoma, associated DCIS?"
For cases diagnosed 1998-2003: Code size of primary tumor as 013. The phrasing suggests that the infiltrating ductal carcinoma measures 1.3 cm. DCIS is also present, but no size mentioned.
EOD-Clinical Extension/EOD-Lymph Nodes--Prostate: How do you code clinical extension and lymph nodes for path only prostate cases treated with a TURP? Would clinical extension be coded to unknown or localized, NOS?
For cases diagnosed 1998-2003: Code the EOD-Clinical Extension field to 30 [localized, NOS] and the EOD-Lymph Nodes field to 0 [no lymph node involvement]. Per Note 7: Use code 30 when there is insufficient information as to whether the tumor is clinically apparent or inapparent but the tumor is confined to the prostate. This is an example of a case where there is insufficient information as to whether the tumor is clinically apparent or inapparent. Assume the tumor is confined to the prostate.
EOD-Pathology Extension--Prostate: Is extracapsular extension implied by the phrase, "involvement of periurethral or urethral margins"? See Description.
The prostatectomy final pathology diagnosis states that the tumor involves the periurethral margin. The microscopic describes involvement of the urethral margin.
For cases diagnosed 1998-2003: Code the EOD-Extension field in the 20-34 range, which implies no extension beyond the prostate. Disregard involvement of periurethral margin or urethral margin, NOS, unless the pathologist or surgeon specifically mentions "extraprostatic urethra" involvement.
