Malignant neoplasm of tail of pancreas

This code signifies a primary cancerous tumor originating in the distal portion of the pancreas, specifically the tail. This malignancy involves uncontrolled growth of abnormal cells within the pancreatic tissue located in the tail region.

Use this code when documentation clearly identifies a primary malignant neoplasm located in the tail of the pancreas. This diagnosis is typically confirmed through imaging studies (e.g., CT, MRI) and biopsy results. It should be applied when the physician explicitly states the tumor's origin in the pancreatic tail.

• Ensure the documentation specifies "tail of pancreas" to differentiate from other pancreatic regions.
• Do not use this code for secondary or metastatic pancreatic cancer; use the appropriate secondary malignancy code.
• Sequence this code as the primary diagnosis when it is the reason for the encounter or treatment.
