Posterior subluxation of left radial head, sequela

This code signifies a long-term complication or residual effect stemming from a prior posterior displacement of the left radial head, where the joint surfaces are no longer perfectly aligned but remain in partial contact. It indicates that the patient is experiencing ongoing issues directly attributable to this past injury, rather than an acute event.

Apply this code when documenting a patient presenting with chronic pain, limited range of motion, instability, or other persistent symptoms in the left elbow or forearm that are a direct consequence of a previously diagnosed posterior radial head subluxation. This is appropriate for follow-up visits addressing these lasting effects, not the initial injury.

• Always link this sequela code to an external cause code (V00-Y99) if the original injury's cause is known and relevant.
• Do not use this code for acute or current subluxations; those require codes from the acute injury section.
• Ensure documentation clearly states the chronic nature of the condition and its direct link to a past posterior radial head subluxation.
