Anterior subluxation of unspecified humerus, sequela

This code indicates a long-term complication or residual effect stemming from a prior anterior subluxation of the humerus, where the specific side (left or right) is not documented. It signifies that the shoulder joint's partial dislocation, which occurred in the past, is now causing ongoing issues or conditions.

Apply this code when a patient presents with a current condition directly attributable to an old anterior shoulder subluxation, and the medical record does not specify which shoulder was affected. This is appropriate for chronic instability, pain, or functional limitations that are a direct consequence of the previous injury.

• Always assign this code as a secondary diagnosis, following the code for the current condition or symptom.
• Ensure the medical record clearly links the current presentation to a prior anterior subluxation.
• If the laterality of the subluxation is documented, select the more specific code (S43.011S or S43.012S).
