Nondisp segmental fx shaft of humerus, unsp arm, sequela

This code signifies a past injury involving a fracture of the humerus shaft that broke in at least two places, creating a segment of bone. The fractured pieces remained in their normal alignment. The specific arm affected is not documented, and the "S" suffix indicates that this is a sequela, meaning it's a late effect or complication of the original injury, not the acute event.

Use this code when documenting a long-term consequence or residual condition stemming from a previously sustained nondisplaced segmental fracture of the humerus shaft, where the laterality of the arm was not specified in the original injury documentation. This could include chronic pain, limited range of motion, nonunion, or malunion, after the initial healing phase has passed.

• Ensure documentation clearly states the condition is a sequela (late effect) of a prior fracture.
• Only use this code when the specific arm (left or right) is not documented in the patient's record.
• Do not use for the initial acute fracture; a different code without the "S" suffix would be appropriate for the active treatment phase.
