Immersion foot, left foot, initial encounter

This code signifies a non-freezing cold injury to the left foot, resulting from prolonged exposure to cold and wet conditions. Immersion foot, also known as trench foot, typically presents with numbness, pain, swelling, and discoloration of the affected foot.

This code is appropriate for the initial encounter with a patient presenting with symptoms of immersion foot specifically affecting the left foot. This includes situations where the patient is first seen for diagnosis and initiation of treatment for this condition.

• Ensure documentation clearly specifies the left foot as the affected site.
• Confirm this is the first time the patient is being treated for this specific episode of immersion foot.
• Do not use for frostbite, which involves tissue freezing and has distinct ICD-10-CM codes.
