Oth physeal fracture of lower end of ulna, unsp arm, sequela

This code signifies a past injury involving a fracture of the growth plate (physis) at the lower end of the ulna, the bone on the pinky-finger side of the forearm. The specific arm affected is not documented, and the "sequela" indicates that this code is used to report a condition or complication arising as a direct result of the initial fracture, even after the acute phase of healing has passed.

Use this code when documenting a long-term complication or residual effect stemming from a previously sustained physeal fracture of the distal ulna, where the laterality of the original injury is unknown. This could include conditions such as growth arrest, angular deformity, or chronic pain directly attributable to the old fracture. It is appropriate for follow-up encounters addressing these persistent issues.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the previous physeal fracture of the distal ulna.
• Avoid using this code for acute or initial injury encounters; it is strictly for sequela reporting.
