Nondisp fx of base of nk of l femr, 7thR

This code describes a situation where a patient has a previously treated, nondisplaced fracture of the base of the neck of their left femur, but the fracture has healed incorrectly (malunion). This specific malunion occurred following an open fracture of type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and contamination at the time of the initial injury.

Use this code for a patient presenting for follow-up care, rehabilitation, or further surgical intervention related to a malunited left femoral neck fracture. The original injury must have been an open fracture of the specified types, and the fracture was initially nondisplaced. This code is appropriate when the malunion is the primary focus of the encounter.

• Ensure documentation clearly specifies "malunion" and the "subsequent encounter" status.
• Verify the original fracture was a nondisplaced base of neck of the left femur and an open fracture type IIIA, IIIB, or IIIC.
• Do not use for nonunion; a separate code exists for that complication.
