Corrosion of second degree of scalp, subsequent encounter

This code signifies a second-degree chemical burn to any part of the scalp, indicating damage that extends beyond the epidermis into the dermis, characterized by blistering, pain, and redness. The "subsequent encounter" designation means this code is used for follow-up care after the initial treatment of the corrosion.

Use this code for patients presenting for ongoing management, wound care, or evaluation of healing for a previously diagnosed second-degree chemical burn to the scalp. This includes visits for dressing changes, infection checks, or assessment of scar formation following the initial injury.

• Always ensure the documentation specifies "corrosion" (chemical burn) rather than a thermal burn.
• Verify the encounter type is indeed "subsequent" and not the initial treatment or sequela.
• Confirm the degree of the burn is explicitly documented as "second degree."
