Corrosion of third degree of scalp, initial encounter

This diagnosis code signifies a severe burn injury affecting the scalp, characterized by full-thickness tissue destruction extending through all layers of the skin and potentially into underlying structures. The injury presents with charring, a leathery appearance, and often a lack of pain due to nerve damage. This specific code is for the initial treatment phase of such an injury.

Apply this code when documenting the first encounter for a patient presenting with a third-degree corrosion (chemical burn) to any part of the scalp. This includes the initial assessment, debridement, and any immediate medical or surgical interventions performed for the acute injury. It is appropriate for emergency department visits or initial hospital admissions related to this specific burn.

• Ensure documentation clearly specifies "third degree" and "scalp" for accurate code assignment.
• Confirm the encounter is the "initial encounter" for this specific injury; subsequent care will use different encounter characters.
• Distinguish between thermal burns (T20.3) and corrosion/chemical burns (T20.7) based on the etiology documented.
