Nondisp commnt fx shaft of ulna, unsp arm, 7thQ

This code describes a follow-up visit for a patient who previously sustained an open, comminuted fracture of the ulna shaft in an unspecified arm, which is now healing with malunion. "Comminuted" indicates the bone is broken into multiple fragments, and "nondisplaced" means the bone fragments are still in their anatomical alignment. "Malunion" signifies that the fracture has healed, but in an unsatisfactory position or alignment.

This code is appropriate for subsequent encounters where a patient is being managed for a previously treated open ulna shaft fracture (Type I or II) that has healed incorrectly. This could include visits for ongoing physical therapy, assessment of functional limitations due to the malunion, or discussions regarding potential corrective surgical interventions. It specifically applies when the initial injury involved an open fracture of either Type I or Type II severity.

• Ensure documentation clearly states "malunion" as the current healing status of the fracture.
• Verify the original fracture was an open fracture, Type I or II, as this is a key specificity for the "Q" seventh character.
• Do not use this code for initial treatment or for nonunion, which implies a complete failure of the bone to heal.
