External constriction of right forearm, subsequent encounter

This code signifies an injury to the right forearm caused by external compression or binding, such as from a tight band, clothing, or other object. The "subsequent encounter" indicates that this code is used for care received after the initial treatment of the injury, such as during follow-up appointments, wound care, or rehabilitation.

Apply this code when a patient presents for ongoing management of a right forearm injury resulting from external constriction. This includes scenarios like a follow-up visit for a patient who initially presented with a tourniquet injury, or for continued care of skin damage caused by a constricting cast or bandage.

• Ensure the documentation clearly specifies the right forearm as the affected site.
• Verify that the encounter is indeed "subsequent" and not the initial treatment for the constriction injury.
• Always code an external cause code (V00-Y99) in conjunction with this code to describe the circumstances of the injury.
