EOD Primary Tumor
This input is used for staging
Notes
**Note 1:** When both the Federation Internationale de Gynecologie et d'Obstetrique (FIGO) stage and extension information on the primary tumor are available, use the extension information to assign the code in preference to a statement of FIGO stage. **Note 2:** Tumors in codes 100-250 with malignant ascites are coded 300. * Ascites, NOS is negative **Note 3:** Both extension to and/or discontinuous metastasis to any of the following pelvic organs are included in code 450 - Bladder and bladder serosa - Broad ligament (mesovarium) - Cul de sac - Parametrium - Pelvic peritoneum - Pelvic wall - Rectosigmoid - Rectum - Sigmoid colon - Sigmoid mesentery - Ureter, pelvic **Note 4:** Peritoneal implants may also be called seeding, salting, talcum powder appearance, or studding **Note 5:** If implants are mentioned, determine whether they are in the pelvis or in the abdomen and code appropriately. If the location of the implants is not specified, code 750. **Note 6:** Both extension to and/or discontinuous metastasis to any of the following abdominal organs by way of peritoneal seeding or implants are included in codes 600-750 - Abdominal mesentery - Diaphragm - Gallbladder - Intestine, large (except rectum) - Kidneys - Liver (peritoneal surface) - Omentum (infracolic, NOS) - Pancreas - Pericolic gutter - Peritoneum, NOS - Rectosigmoid - Sigmoid colon - Small intestine - Spleen (capsular involvement only) - Stomach - Ureters (outside pelvis) **Note 7:** Direct extension and/or metastasis to the liver or splenic parenchyma are coded in EOD Mets. **Note 8:** In some registries benign/borderline ovarian tumors are reportable by agreement. * If the tumor being reported is benign or borderline, code 999.Default
