]> C18.1 Appendix Note: Carcinoid tumor and neuroendocrine carcinoma (histology codes 8153, 8240-8242, 8246, 8249) of the appendix are included in the "CarcinoidAppendix" schema. CS Tumor Size Code Description 000 No mass/tumor found 001-988 989 989 mm or larger 990 Microscopic focus or foci only and no size of focus given 991 Described as "less than 1 cm" 992 Described as "less than 2 cm," or "greater than 1 cm," or "between 1 cm and 2 cm" 993 Described as "less than 3 cm," or "greater than 2 cm," or "between 2 cm and 3 cm" 994 Described as "less than 4 cm," or "greater than 3 cm," or "between 3 cm and 4 cm" 995 Described as "less than 5 cm," or "greater than 4 cm," or "between 4 cm and 5 cm" 998 999 CS Extension Note 1: Ignore intraluminal extension to adjacent segment(s) of colon; code depth of invasion or extracolonic spread as indicated. Note 2: Mucinous tumors are identified by morphology codes 8480, 8481, and 8490. Note 3: One or more malignant satellite peritumoral nodules or tumor deposits (TD) in the periappendiceal adipose tissue of a primary carcinoma without histologic evidence of residual lymph node in the nodule may represent discontinuous spread, venous invasion with extravascular spread, or a totally replaced lymph node. Replaced nodes are counted as positive nodes and coded in CS Lymph Nodes. TD representing discontinuous spread or venous invasion are coded in CS Extension, code 450, and the number of TD representing discontinuous spread or venous invasion is coded in CS Site-Specific Factor 4. Note 4: Tumor that is adherent to other organs or structures, macroscopically, is classified cT4b. If tumor is present in adhesion(s) upon microscopic examination, the tumor is classified as pT4b. Use code 565 for macroscopic adhesions if no pathologic confirmation, and for pathologically confirmed tumor in adhesions. However, if no tumor is present in adhesion(s) upon microscopic examination, the classification is based upon extent of tumor invasion into or through the wall; use codes 000-160, 200, 400, 450, 500-550 as appropriate to describe the microscopically confirmed depth of tumor invasion for these cases. Use codes 600-650, 665, 700-810 to code invasion of underlying structures from the adherent tumor. Note 5: Codes 600-650 and 700-750are used for contiguous extension from the site of origin. Except for intraperitoneal metastases limited to the right lower quadrant (RLQ) of the abdomen for mucinous tumors, discontinuous involvement is coded in CS Mets at DX. Note 6: High-grade dysplasia is not always collected by cancer registries but, if collected, it should be coded 000 or 050.

Replaced nodes are counted as positive nodes and coded in CS Lymph Nodes. TD representing discontinuous spread or venous invasion are coded in CS Extension, and the number of TD representing discontinuous spread or venous invasion is coded in CS Site-Specific Factor 4. Note 3: Superior and inferior mesenteric nodes are coded in CS Mets at DX. Mesenteric nodes, NOS are coded in CS Lymph Nodes. Note 4: The number of positive regional nodes is required to calculate the correct N category for this schema. Use codes 400 and 450 a when the pathology report assigns an N1 or N2 category but the specific information about number of nodes involved is not available. Use codes 100 - 300 rather than codes 400 or 450 when information about the number of positive nodes is available, or when nodes are clinically positive but not removed for examination.

Do not include information on regional lymph nodes that is based on surgical observation or diagnostic lymph node biopsy. Note 2: In the rare instance that the number of clinically positive nodes is stated but a clinical N category is not stated, code 1-3 nodes as 100 (N1), and 4 or more nodes as 200 (N2). Note 3: If there is no diagnostic work-up to assess regional lymph nodes, use code 999. Do not apply the inaccessible nodes rule that presumes unmentioned nodes to be negative.

It is considered to be of particular importance for mucinous carcinomas (morphology codes 8480, 8481, and 8490). Note 2: Select the code for the highest grade from the most representative sample of primary tumor tissue as described on the pathology report. Note 3: The term "undifferentiated" should not apply to mucinous tumors because a tumor that makes mucin is, by definition, differentiated into mucin-producing tumor cells.

Note 2: Record to the nearest tenth in Unit/milliliter (U/mL) the highest CA 19-9 lab value documented in the medical record prior to treatment. For example, code a pre-treatment CA 19-9 value of 60 U/mL as 600. Note 3: Code 000 is reserved for exactly 0.0 U/mL (no measurable amount of CA 19-9). Do not round tiny values down to 0.0 U/mL; any measured value less than or equal to 0.1 U/mL should be coded 001. For code 001, also round 0.11-0.14 U/mL down to 0.1 U/mL. For codes 002-980, round values to the nearest tenth of a U/ml. Note 4: Use code 997 if an interpretation is documented but the actual lab value is not available in the record.
