EOD Mets

This input is used for staging

Notes

**Note 1:** Use code 50 only when there are liver metastasis WITH other metastatic involvement. * If there are multiple distant mets but liver is not one of them, code 30. **Note 2:** Use code 70 when the only information is “distant metastasis, NOS,” and there is no documentation regarding the specific metastases. * If there are specific metastasis documented that are not listed in codes 10, 20, or 30, assign code 30 for “other specified distant metastasis.”
