External constriction of unspecified shoulder, sequela

This code signifies a long-term or late effect resulting from an external force or object that compressed or constricted an unspecified shoulder. This constriction led to a lasting impairment, deformity, or other residual condition. The original injury or event that caused the constriction is no longer acute.

Use this code when documenting a chronic condition or complication of the shoulder that is directly attributable to a past external constriction. This applies when the acute phase of the constriction has resolved, but its effects persist. Examples include nerve damage, vascular compromise, or muscle atrophy in the shoulder area due to a prior prolonged tourniquet application, tight cast, or other external binding.

• Always sequence this code after the code(s) for the specific sequela (e.g., nerve palsy, muscle weakness) it describes.
• Ensure documentation clearly links the current shoulder condition to a previous external constriction.
• Avoid using this code for acute or current external constriction; those would be coded with an acute injury code.
