Other instability, left shoulder

This code signifies a condition where the left shoulder joint exhibits abnormal or excessive movement, but not a complete dislocation. This instability can manifest as subluxation, apprehension, or a feeling of the shoulder "giving out" without fully separating. It indicates a chronic or recurrent issue rather than an acute traumatic event.

Use this code when documentation specifies instability of the left shoulder that is not a complete dislocation. This is appropriate for patients presenting with symptoms like recurrent subluxations, chronic pain due to instability, or a history of the shoulder "slipping out" without requiring reduction. Documentation should clearly state "instability" and specify the left shoulder.

• Ensure the documentation explicitly states "instability" and specifies the left shoulder.
• Do not use this code for acute traumatic dislocations; those have specific S codes.
• Distinguish from M24.212 (Disorder of ligament, left shoulder) which implies a specific ligamentous injury rather than general instability.
