External constriction of left shoulder, sequela

This code signifies a long-term or late effect of external constriction affecting the left shoulder. This could result from a previous injury, tight clothing, or other external forces that restricted blood flow or nerve function, leading to ongoing symptoms or functional impairment in the shoulder.

Apply this code when documenting a current condition of the left shoulder that is a residual effect of a past external constriction. This would be used in conjunction with a code describing the specific sequela (e.g., nerve damage, muscle atrophy, circulatory compromise) if known.

• Always sequence this sequela code after the code identifying the specific manifestation of the constriction.
• Ensure documentation clearly links the current left shoulder condition to a previous external constriction event.
• Do not use for acute or current external constriction; this code is specifically for the sequela.
