Unsp trochan fx left femur, subs for clos fx w nonunion

This code describes a left femur fracture located in the trochanteric region, where the specific type of trochanteric fracture is not documented. It indicates that the fracture is not healing properly (nonunion) and the patient is in a subsequent phase of care, with the fracture being treated as closed (skin intact).

Use this code for follow-up encounters when a patient has a previously diagnosed, unspecified trochanteric fracture of the left femur that is not uniting. This applies when the fracture is being managed non-surgically or after initial surgical fixation, and the skin over the fracture site remains intact.

• Ensure documentation specifies "unspecified" trochanteric fracture and "left" femur.
• Verify "nonunion" is clearly documented for the fracture.
• Confirm this is a subsequent encounter for a closed fracture.
