Other fracture of lower end of left ulna, sequela

This code signifies a long-term complication or late effect resulting from a fracture of the lower portion of the left ulna, excluding specific fracture types like Salter-Harris or Colles' fractures. It indicates that the initial fracture has healed, but the patient is now experiencing residual issues directly attributable to that past injury.

Apply this code when documenting conditions such as chronic pain, nonunion, malunion, limited range of motion, or nerve damage that are directly linked to a previously sustained fracture of the distal left ulna. This code is appropriate for encounters addressing these persistent sequelae, not the initial acute fracture treatment.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., chronic pain, malunion).
• Ensure documentation clearly links the current condition to a past fracture of the lower left ulna.
• Verify that the encounter is for the sequela and not for ongoing treatment of the acute fracture itself.
