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 is characterized by uncontrolled cell growth and has the potential to invade surrounding tissues and metastasize to distant sites.

Apply this code when documentation explicitly states a malignant neoplasm located in the tail of the pancreas. This diagnosis is typically confirmed through imaging studies (e.g., CT, MRI) and biopsy results. Use for initial diagnosis and active treatment phases of the primary tumor.

• Ensure the documentation clearly specifies "tail of pancreas" to differentiate from other pancreatic regions.
• Do not use for secondary (metastatic) malignancies to the pancreatic tail; use appropriate secondary neoplasm codes.
• Consider sequencing this code as the primary diagnosis when it is the reason for the encounter, followed by any associated symptoms or complications.
