Disp fx of greater trochanter of unsp femr, 7thN

This code describes a situation where a patient has a previously treated, displaced fracture of the greater trochanter of an unspecified femur that has failed to heal properly (nonunion). The original fracture was an open fracture, classified as type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and contamination. This specific code is used during a subsequent encounter for ongoing management of this nonunion.

Use this code when documenting follow-up care for a patient whose open greater trochanteric fracture (types IIIA, IIIB, or IIIC) has not united. This includes scenarios where the patient is undergoing further surgical intervention, conservative management, or evaluation for the nonunion. It signifies that the initial treatment has not resulted in bone healing.

• Ensure documentation clearly specifies "nonunion" and the original fracture was an open type IIIA, IIIB, or IIIC.
• Verify laterality (left or right) if specified in the medical record; "unspecified" is used when not documented.
• Confirm this is a "subsequent encounter" for the nonunion, not the initial treatment of the fracture.
