Corrosion of third degree of right foot, initial encounter

This code signifies a severe burn injury affecting the full thickness of the skin and underlying tissues on the patient's right foot. It indicates that the damage extends through all layers of the dermis, often involving subcutaneous fat, muscle, or bone, resulting in a white, leathery, or charred appearance.

Apply this code when documenting a patient's initial presentation for a third-degree corrosion (chemical burn) to the right foot. This includes emergency department visits, initial hospital admissions, or the first outpatient encounter for this specific injury.

• Ensure the documentation clearly specifies "third degree" and "right foot" for accurate code assignment.
• Verify the cause of the burn is explicitly stated as "corrosion" (chemical burn) rather than thermal.
• Confirm this is the initial encounter for treatment of this specific injury; subsequent encounters will require a different seventh character.
