"notes" : "**Note 1**: High-grade squamous intraepithelial lesions (HSIL) and anal intraepithelial neoplasia (AIN) grade II III are not normally collected by cancer registries. AIN II III or AIN III is reportable to standard-setters (except the Commission on Cancer). If your registry collects any of these, use code 000.\n\n**Note 2**: The assignment of T1, T2 , and T3 categories for tumors of the anus is based on tumor size. A physician's statement of the T category may be used to code CS Tumor Size and/or CS Extension if this is the only information in the medical record regarding one or both of these fields. However the two fields are coded independently: for example the record may document size but not extension, other than the physician's statement of the T category. Use code 310, 320, 330, or 850 as appropriate to code CS Extension based on a statement of T when no other extension information is available.\n\n**Note 3**: Code incidental finding of malignancy in hemorrhoid according to greatest extension of tumor into wall of anus. Code as Localized, NOS if extension not specified.\n\n**Note 4**: Codes 400-750 are used for contiguous extension from the site of origin. Discontinuous involvement is coded in CS Mets at DX.",
"footnotes" : "- For CS Extension codes 100-400 ONLY, the T category for AJCC 7 staging is assigned based on the value of CS Tumor Size, as shown in the Extension Size Table for this schema.\n- For CS Extension codes 100-400 ONLY, the T category for AJCC 6 staging is assigned based on the value of CS Tumor Size, as shown in the Extension Size Table for this schema.",
