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

This code signifies a fracture of the main body (shaft) of the left thigh bone, where the specific type of fracture is not documented. It indicates that the patient is in a later stage of healing for a closed fracture (skin intact), but 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 fracture of the left femoral shaft presents with evidence of delayed union. This would typically be documented by the physician during an office visit, hospital follow-up, or rehabilitation setting.

• Ensure documentation clearly states "delayed healing" for a closed fracture.
• Verify the laterality (left femur) is explicitly mentioned in the medical record.
• Do not use this code for initial encounters or for open fractures; different codes apply.
