Path fx in neopltc disease, l ulna, subs for fx w delay heal

This code signifies a fracture of the left ulna that occurred due to an underlying neoplastic (cancerous) process, rather than trauma. The "subsequent encounter" indicates the patient is receiving routine care during the healing phase of the fracture, and "delayed healing" specifies that the fracture is not progressing to union at the expected rate.

Use this code for follow-up encounters when a patient is being managed for a pathological fracture of the left ulna caused by cancer, and the fracture is demonstrating delayed healing. Documentation should clearly state the pathological nature of the fracture, its location, and the ongoing management for delayed healing.

• Always sequence the underlying neoplasm code first, followed by this code.
• Ensure documentation explicitly states "delayed healing" for the fracture; otherwise, a code for routine healing would be more appropriate.
• Verify the laterality (left ulna) is accurately documented to avoid coding errors.
