EOD Primary Tumor

Notes

**Note 1:** In case of multifocal non-invasive and in situ tumors, code 050. **Note 2:** Tumor involving both renal pelvis and ureter (unifocal or multifocal) is classified by the depth of greatest invasion in either organ. **Note 3:** Direct invasion of the bladder by a ureteral tumor is classified by the depth of greatest invasion of the bladder or ureter.
