Displ subtrochnt fx l femr, 7thN

This code describes a situation where a patient has a subtrochanteric fracture of the left femur that is displaced and has not healed properly (nonunion). This specific instance involves an open fracture, classified as Type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and contamination. The "subsequent encounter" aspect means the patient is receiving follow-up care for this previously diagnosed and treated injury.

Use this code for patients presenting for ongoing management, evaluation, or treatment of a nonunion of a displaced subtrochanteric fracture of the left femur. This is applicable when the initial injury was an open fracture of a severe type (IIIA, IIIB, or IIIC). This code would be appropriate for clinic visits, hospital admissions for revision surgery, or other encounters related to the persistent nonunion.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" status for this specific fracture.
• Verify the laterality (left femur) and the displaced nature of the subtrochanteric fracture.
• Confirm the original open fracture type was IIIA, IIIB, or IIIC, as this impacts code selection.
