Corrosion of second degree of nose (septum), sequela

This code signifies a second-degree chemical burn to the nasal septum, indicating damage that extends beyond the epidermis into the dermis, resulting in blistering and significant pain. The "sequela" designation means this code is used for complications or conditions arising directly from a previous corrosion, after the acute phase of the injury has passed.

Apply this code when documenting a patient presenting with a chronic or residual condition directly attributable to a past second-degree chemical burn of the nasal septum. This would include scenarios like scarring, persistent pain, or structural deformities of the septum that are a direct consequence of the original corrosive injury. It is not for use during the initial treatment of the acute burn.

• Always ensure documentation clearly links the current condition to a prior chemical burn of the nasal septum.
• Do not use this code for acute or active second-degree corrosive injuries; instead, use the appropriate acute phase code.
• Verify that the burn was specifically to the nasal septum and not other parts of the nose.
