Subluxation of distal end of right ulna, sequela

This code signifies a partial dislocation of the distal (far) end of the ulna bone in the right forearm, specifically when this condition is a long-term consequence or complication of an initial injury. It indicates that the current presentation is a residual effect rather than an acute event.

Use this code for patients presenting with chronic instability, pain, or functional limitations in the right wrist due to a previously sustained subluxation of the distal ulna. This applies when the subluxation is no longer acute but represents a persistent issue requiring ongoing management or evaluation.

• Requires a seventh character 'S' to indicate sequela, meaning the current encounter is for complications or conditions arising from the initial injury.
• Do not use for acute subluxations; those would be coded with an 'A' (initial encounter) or 'D' (subsequent encounter) seventh character.
• Always consider accompanying codes for any associated pain, instability, or functional impairment.
