Nondisp oblique fx shaft of l tibia, 7thK

This code signifies a left tibial shaft fracture that is not displaced and runs obliquely, meaning it's at an angle to the bone's long axis. The "subsequent encounter" indicates the patient is receiving follow-up care for this fracture, and "nonunion" specifies that the bone fragments have failed to heal together after a reasonable period.

Apply this code when documenting ongoing treatment for a previously diagnosed, non-displaced, oblique fracture of the left tibial shaft where the bone has not successfully united. This is appropriate for patients undergoing continued management, such as bracing, physical therapy, or surgical planning, due to the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the left tibia.
• Verify the fracture is indeed oblique and non-displaced.
• Confirm this is a subsequent encounter for the fracture, not the initial treatment.
