Nondisp segmental fx shaft of ulna, unsp arm, sequela

This code signifies a past injury involving a fracture of the ulna shaft that broke into at least three pieces (segmental) but where the bone fragments remained in their normal anatomical alignment (nondisplaced). The specific arm affected is not documented, and the code indicates that this fracture is now a sequela, meaning it is a residual condition or complication arising from the original injury.

Use this code when documenting a long-term effect or complication directly attributable to a previously sustained nondisplaced segmental ulna shaft fracture. This is appropriate when the patient is presenting for treatment of a chronic issue related to the old fracture, such as pain, limited range of motion, or nonunion, after the initial healing phase has passed.

• Always ensure documentation clearly links the current condition to the old fracture as a sequela.
• Verify that the fracture was indeed segmental and nondisplaced based on prior imaging and physician notes.
• Avoid using this code for the initial treatment of an acute fracture; it is strictly for sequelae.
