Unsp fx l low leg, subs for opn fx type I/2 w delay heal

This code signifies an unspecified fracture of the left lower leg that was initially an open fracture of Gustilo type I or II, and the patient is now presenting for follow-up care due to delayed healing. It indicates that the bone is not mending at the expected rate for this type of injury.

Use this code for patients returning for ongoing management of a left lower leg fracture where the initial injury was an open fracture (type I or II) and healing has been slower than anticipated. This applies to situations where the fracture site is still open or has not fully consolidated within the typical timeframe.

• Ensure documentation clearly states "delayed healing" and specifies the initial open fracture type (I or II).
• Verify laterality (left lower leg) is explicitly documented.
• This code is for subsequent encounters, not the initial treatment of the fracture.
