Path fx in neopltc dis, unsp ulna & rad, 7thP

This code signifies a fracture of an unspecified ulna and radius that occurred due to an underlying neoplastic (cancerous) process, which has subsequently healed incorrectly (malunion). The patient is in a follow-up phase of care for this specific fracture complication.

Apply this code for patients presenting with a malunited pathological fracture of the ulna and/or radius, where the original fracture was caused by a tumor, and they are receiving ongoing treatment or evaluation for this malunion. Documentation should clearly state "pathological fracture," "neoplastic disease," "ulna and/or radius," and "malunion" in a subsequent encounter.

• Requires documentation of a causal link between the neoplastic disease and the fracture.
• Confirm the encounter type is "subsequent" for the fracture care, not initial or sequela.
• Always sequence the underlying neoplasm code first, followed by this code.
