Path fx in neopltc disease, r foot, subs for fx w nonunion

This code signifies a fracture of the right foot that occurred due to an underlying neoplastic (cancerous) process, and the fracture has failed to heal properly (nonunion). This specific code is used for follow-up encounters after initial treatment, where the nonunion is still being addressed.

Apply this code for patients presenting for ongoing management of a right foot fracture complicated by nonunion, where the fracture was caused by a tumor. Documentation should clearly state the neoplastic etiology of the fracture, the anatomical site (right foot), the presence of nonunion, and that this is a subsequent encounter for care.

• Always sequence the underlying neoplasm code first, followed by this code.
• Distinguish carefully between initial, subsequent, and sequela encounters based on the "K" seventh character.
• Ensure documentation explicitly states "nonunion" and the neoplastic origin of the fracture to support this specific code.
