Unsp fracture of left femur, subs for clos fx w delay heal

This code signifies a left femur fracture where the specific type of fracture (e.g., transverse, spiral) is not documented, and the patient is in a phase of treatment following the initial care. The fracture is closed, meaning the skin is intact, and the healing process is progressing slower than expected.

This code is appropriate for follow-up encounters when a patient with a previously diagnosed, unspecified closed left femur fracture is experiencing delayed union. This includes situations where the physician is monitoring the healing, performing follow-up imaging, or adjusting treatment plans due to the slow healing.

• Ensure documentation clearly states "left femur" and "unspecified fracture type" for accurate assignment.
• Verify the encounter is for a "subsequent encounter" and that "delayed healing" is explicitly documented or clearly implied by the clinical context.
• Confirm the fracture is "closed"; if open, a different seventh character would be required.
