External constriction of left upper arm, sequela

This code signifies a long-term or late effect resulting from external pressure or compression on the left upper arm. This constriction can lead to various chronic issues such as nerve damage, circulatory impairment, or muscle atrophy, manifesting after the initial constricting event has resolved.

Apply this code when documenting a patient presenting with a current condition in the left upper arm that is a direct consequence of a past external constriction. Examples include chronic pain, weakness, or sensory deficits in the left upper arm attributed to a previous tight bandage, cast, or prolonged pressure.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., nerve damage, muscle atrophy).
• Ensure documentation clearly links the current left upper arm condition to a past external constriction event.
• Do not use this code for acute or current external constriction; instead, use the appropriate acute injury code.
