Malignant neoplasm of short bones of unspecified upper limb

This code signifies a cancerous tumor originating in the short bones of an upper limb, such as the carpals or phalanges, when the specific side (right or left) is not documented. It indicates a primary malignancy rather than a metastatic lesion.

Apply this code when documentation confirms a primary malignant neoplasm of the short bones of the hand or wrist, and the laterality of the affected limb is unspecified. This is appropriate for pathology reports confirming malignancy in these bones without specifying right or left.

• Do not use this code if the laterality (right or left) of the upper limb is documented; instead, choose a more specific code.
• Ensure the documentation clearly states "malignant neoplasm" and not a benign tumor or a secondary (metastatic) site.
• Sequence this code as the primary diagnosis when the neoplasm is the reason for the encounter, followed by any associated complications or treatments.
