Corrosion of first degree of scalp, subsequent encounter

This diagnosis code indicates a superficial burn to the scalp, affecting only the outermost layer of skin (epidermis), which was sustained in the past and is now being treated or evaluated again. It typically presents with redness, mild pain, and no blistering.

Use this code when a patient presents for follow-up care, wound check, or further treatment of a first-degree burn to any part of the scalp that occurred previously. This includes situations where the initial injury has already been addressed and the patient is returning for subsequent management.

• Ensure the documentation clearly states "first degree" and specifies the "scalp" as the affected body part.
• The "D" seventh character signifies a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Do not use for initial treatment of the burn; a different seventh character would be appropriate for the initial encounter.
