Secondary malignant neoplasm of other urinary organs

This code signifies the presence of a metastatic cancerous tumor that originated from a primary malignancy elsewhere in the body and has spread to urinary organs other than the bladder, kidney, or ureter. This includes secondary neoplasms affecting structures like the urethra, prostate (in males), or other unspecified urinary sites.

Apply this code when documentation clearly indicates a malignant neoplasm in a urinary organ (excluding bladder, kidney, or ureter) that is explicitly stated as metastatic from a primary site. This is typically supported by pathology reports, imaging studies, and physician notes detailing the metastatic nature of the tumor.

• Always sequence the primary malignant neoplasm first, followed by this code for the secondary site.
• Distinguish carefully between primary urinary organ cancers and secondary (metastatic) involvement.
• Ensure the documentation specifies "other urinary organs" to avoid miscoding to bladder, kidney, or ureter.
