Benign neoplasm of unspecified kidney

This code signifies the presence of a non-cancerous growth or tumor originating in the kidney, where the specific side (left or right) is not documented. These benign neoplasms are typically slow-growing and do not metastasize to other parts of the body.

Assign this code when medical record documentation clearly identifies a benign renal neoplasm but lacks laterality. This is appropriate for pathology reports confirming a benign tumor without specifying the affected kidney, or imaging reports describing a mass consistent with a benign neoplasm where the side is not explicitly stated.

• Do not use this code if the documentation specifies the laterality of the benign renal neoplasm; instead, use D30.01 or D30.02.
• Ensure the pathology report or imaging study explicitly states "benign" to differentiate from malignant or uncertain behavior.
• If the documentation is ambiguous regarding benign vs. malignant, query the provider for clarification before assigning this code.
