Unsp fx shaft of l ulna, 7thH

This code describes a situation where a patient has an unspecified fracture of the shaft of their left ulna, which was initially an open fracture of either Type I or Type II. The current encounter is for follow-up care, specifically addressing delayed healing of this open fracture.

Use this code for subsequent encounters when a patient with a previously diagnosed open Type I or Type II fracture of the left ulnar shaft is experiencing delayed healing. This applies when the specific nature of the fracture (e.g., transverse, oblique) was not documented at the initial encounter.

• Ensure documentation clearly specifies "delayed healing" for this subsequent encounter.
• Verify the fracture is of the left ulna shaft and was initially an open fracture (Type I or II).
• Do not use for initial encounters or for fractures that are healing normally or with nonunion/malunion.
