Unsp fx low end unsp ulna, 7thH

This code describes a fracture of the lower part of the ulna where the specific type of fracture is not documented. It indicates that the initial injury was an open fracture (Type I or II) and the patient is now presenting for follow-up care due to delayed healing of that fracture.

Apply this code when a patient with a previously diagnosed open fracture (Type I or II) of the distal ulna is seen for ongoing management, and the fracture is not healing as expected. This is appropriate when the precise fracture pattern (e.g., transverse, oblique) of the distal ulna was not specified in the initial documentation.

• Requires a seventh character "H" for subsequent encounter with delayed healing.
• Ensure documentation clearly states an "unspecified" fracture of the distal ulna and an initial open fracture type I or II.
• Do not use if the specific fracture type (e.g., Colles', Smith's) is known or if healing is progressing normally.
