CS Extension

Notes

**Note 1**: AJCC considers "in situ carcinoma of the adrenal gland" an impossible diagnosis. Any case so coded is mapped to TX for AJCC stage and in situ Summary Stage. **Note 2**: The assignment of T1 and T2 categories for tumors limited to the adrenal gland 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 codes 200, 250, 400, or 810 as appropriate to code CS Extension based on a statement of T when no other extension information is available. **Note 3**: Use code 300 (Localized, NOS) when no further information is available to assign code 100, 200, or 250.

- For CS Extension codes 100-300 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.
