Unsp fx low end l tibia, 7thH

This code signifies an unspecified fracture of the distal (lower) end of the left tibia that was initially an open fracture (Type I or II). The patient is now in a subsequent encounter, and the fracture is experiencing delayed healing. This indicates the fracture is not progressing to union at the expected rate.

Apply this code for follow-up encounters where a patient with a previously documented open fracture of the lower left tibia is being managed for delayed union. This would include clinic visits for assessment, imaging, or planning further interventions due to the slow healing process. It is appropriate once the initial active treatment for the acute fracture has concluded.

• Ensure documentation clearly specifies "delayed healing" and the fracture is of the lower end of the left tibia.
• Verify the initial fracture was indeed an "open fracture type I or II" as this impacts the seventh character.
• Do not use for nonunion; a different seventh character would be required for that stage of healing.
