Malignant neoplasm of pancreas, part unspecified

This code signifies a cancerous tumor originating in the pancreas, where the specific anatomical location within the organ (e.g., head, body, tail) is not documented. It indicates a primary malignancy of pancreatic tissue.

Apply this code when the medical record clearly states a diagnosis of pancreatic cancer but lacks further specification regarding the precise site within the pancreas. This is appropriate when pathology reports confirm malignancy but do not localize the tumor, or when imaging reports identify a mass consistent with cancer without further anatomical detail.

• Avoid using this code if documentation specifies the tumor's location within the pancreas (e.g., head, body, tail); use a more specific code from category 157.x.
• Always seek clarification from the provider if the documentation is ambiguous regarding the tumor's exact site.
• This code is for primary pancreatic malignancy; do not use for metastatic cancer to the pancreas.
