External constriction of left wrist, subsequent encounter

This code indicates an injury to the left wrist caused by external pressure or compression, such as from a tight band, restraint, or object. It signifies that the patient is receiving follow-up care for this specific injury after the initial treatment phase.

Use this code for patients presenting for subsequent visits related to a left wrist injury due to external constriction. This includes follow-up appointments for wound care, pain management, physical therapy, or monitoring for complications like nerve damage or compartment syndrome, after the initial encounter for the injury.

• Ensure the documentation clearly specifies "left wrist" and "external constriction."
• Verify that the encounter is indeed "subsequent" and not the initial treatment for the injury.
• Always code the underlying cause of the external constriction if known and documented.
