Malignant neoplasm of gallbladder

This code signifies the presence of a primary cancerous tumor originating in the gallbladder. This aggressive malignancy often presents with symptoms such as jaundice, abdominal pain, and weight loss, and is typically diagnosed through imaging and biopsy.

Assign this code when documentation confirms a primary malignant neoplasm of the gallbladder. This includes cases of adenocarcinoma, squamous cell carcinoma, or other primary malignant histological types. Supporting documentation should include pathology reports, operative notes, or physician's diagnostic statements.

• Always confirm the primary site; do not use for metastatic disease to the gallbladder.
• Specify laterality if documented, although the gallbladder is a single organ.
• Ensure documentation clearly distinguishes between benign polyps or other non-malignant conditions of the gallbladder.
