Unsp fx right femur, subs for opn fx type I/2 w delay heal

This code indicates an unspecified fracture of the right femur 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 of that fracture. The specific location or type of femoral fracture is not documented, only that it occurred in the right femur and was open.

Use this code when a patient with a previously diagnosed open right femoral fracture (Gustilo type I or II) is seen for a subsequent visit where the primary concern is that the fracture is not healing as expected. This applies to situations where the fracture has not united within the typical timeframe for healing.

• Ensure documentation clearly specifies "delayed healing" for the subsequent encounter.
• Verify the initial fracture was indeed an open fracture type I or II.
• Do not use for nonunion or malunion; those have separate, more specific codes.
