Unsp fx low end l ulna, 7thH

This code signifies an open fracture of the lower end of the left ulna, where the bone has broken through the skin, and the patient is in a subsequent phase of care due to delayed healing. The open nature of the fracture is classified as Type I or Type II, indicating the severity of the soft tissue damage.

Apply this code when a patient with a previously diagnosed open fracture of the distal left ulna (Type I or II) presents for follow-up care, and the physician documents that the healing process is taking longer than expected. This code is appropriate for ongoing management of the delayed union or nonunion of the fracture.

• Ensure documentation specifies "left ulna" and "lower end" to support laterality and anatomical site.
• Confirm the encounter is "subsequent" and that "delayed healing" of an "open fracture type I or II" is explicitly stated.
• Do not use for initial encounters or for fractures that are healing normally.
