Corrosion of second degree of nose (septum), subs encntr

This code signifies a second-degree chemical burn affecting the nasal septum, specifically when the patient is receiving follow-up care after the initial treatment. A second-degree corrosion involves damage to the epidermis and dermis, often presenting with blistering, pain, and redness.

Apply this code for subsequent visits where a patient is being treated for a second-degree chemical burn to the nasal septum. This includes wound care, monitoring for infection, or assessing healing progress after the initial encounter. It is used after the acute phase of treatment has concluded.

• Ensure documentation clearly specifies "second degree" and "corrosion" (chemical burn) to the nasal septum.
• The "D" in the seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing phase.
• Do not use for initial treatment or for sequelae (late effects) of the burn.
