Malignant neoplasm of pancreatic duct

This code signifies a primary cancerous tumor originating within the ducts of the pancreas. This malignancy is a type of pancreatic adenocarcinoma, specifically identifying its ductal origin. It represents a serious and often aggressive form of pancreatic cancer.

This code is appropriate for confirmed diagnoses of malignant neoplasms arising from the pancreatic ducts. Documentation should clearly state "pancreatic ductal adenocarcinoma," "carcinoma of the pancreatic duct," or similar pathology findings. It is used when the primary site of the malignancy is definitively identified as the pancreatic duct.

• Differentiate from other pancreatic malignancies, such as those of the islet cells or other specified/unspecified parts of the pancreas.
• Ensure documentation specifies "duct" to avoid coding to a more general pancreatic malignancy.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter, followed by any relevant secondary diagnoses or complications.
