Other fracture of upper end of right ulna, sequela

This code indicates a long-term complication or late effect stemming from a previous fracture of the upper portion of the right ulna, specifically involving types of fractures not otherwise specified. These sequelae can include chronic pain, nonunion, malunion, post-traumatic arthritis, or nerve damage that persists after the initial healing period of the original injury.

Apply this code when documenting a patient presenting with a current condition or symptom that is a direct result of an old, healed, or previously treated fracture of the proximal right ulna. This is appropriate when the acute phase of the original fracture has passed, and the current encounter addresses the residual effects.

• Always sequence this "S" code after the code for the specific sequela (e.g., M24.574 for contracture of right wrist, if that's the sequela).
• Ensure documentation clearly links the current condition to a past fracture of the upper right ulna.
• Do not use this code for acute fractures; it is exclusively for late effects.
