Immersion foot, right foot, initial encounter

This code signifies a non-freezing cold injury affecting the right foot, resulting from prolonged exposure to wet and cold conditions. It involves tissue damage due to vasoconstriction and nerve injury, distinct from frostbite. Symptoms typically include numbness, tingling, pain, swelling, and skin discoloration.

Apply this code for a patient presenting with initial diagnosis and treatment for immersion foot specifically affecting their right foot. This would be appropriate for a patient seen in the emergency department or a primary care setting for the first time for this condition. It is used when the injury is acute and the patient is receiving active treatment.

• Ensure documentation clearly specifies the right foot as the affected extremity.
• Verify that the encounter is indeed the "initial encounter" for this specific condition.
• Differentiate from frostbite (T33-T34) and other cold-related injuries.
