Path fx in neopltc dis, left radius, subs for fx w nonunion

This code describes a fracture of the left radius that occurred due to an underlying neoplastic (cancerous) process, which has subsequently failed to heal properly (nonunion). It indicates that the patient is receiving ongoing care for this unhealed pathological fracture.

Use this code for a patient presenting for follow-up treatment of a left radial fracture caused by a tumor, where the fracture has not united. Documentation should clearly state "pathological fracture," "left radius," "nonunion," and indicate that this is not the initial treatment encounter.

• Always sequence the underlying neoplasm code first, followed by this code.
• Ensure documentation specifies "nonunion" for the fracture; if it's healing normally, a different subsequent encounter code would be appropriate.
• Verify laterality (left vs. right) and bone involved (radius) are explicitly documented to avoid miscoding.
