Blister (nonthermal), right foot, initial encounter

This code signifies a non-burn-related fluid-filled lesion on the right foot. It indicates the initial presentation or active treatment phase of such a blister, which may arise from friction, pressure, or other non-thermal causes.

Apply this code when documenting a patient's first visit or active treatment for a blister on their right foot that is not due to heat, cold, or chemical exposure. Examples include blisters from ill-fitting shoes, prolonged standing, or repetitive motion.

• Ensure the documentation clearly specifies the right foot and confirms the non-thermal etiology.
• Verify this is the initial encounter for this specific injury; subsequent care would use a different encounter character.
• Look for associated symptoms or underlying conditions that may require additional codes.
