Notes
**Note 1:** If there are multiple metastatic sites, code based on the largest metastasis.
**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.”
