Dislocation of distal end of unspecified ulna, sequela

This code signifies a long-term complication or late effect resulting from a prior dislocation of the distal end of the ulna, where the specific side (left or right) is not documented. These sequelae can include chronic pain, instability, limited range of motion, or degenerative changes that persist after the initial injury has healed.

Apply this code when documenting a patient presenting with ongoing issues directly attributable to a past dislocation of the distal ulna, and the medical record does not specify which arm was affected. This is appropriate for follow-up encounters addressing residual symptoms or complications from such an injury.

• Always sequence this code after the code for the primary condition or sequela being treated.
• Ensure documentation clearly links the current symptoms to a previous distal ulnar dislocation.
• Avoid using this code for acute dislocations; instead, use the appropriate acute dislocation code with the correct seventh character.
