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

This code signifies a superficial chemical burn to the nasal septum, affecting only the outermost layer of skin, encountered during a follow-up visit. The injury is caused by corrosive substances, leading to redness and mild pain without blistering or tissue loss.

Apply this code when documenting the ongoing management or assessment of a patient who previously sustained a first-degree chemical burn to the nasal septum. This is appropriate for subsequent visits after the initial treatment, such as wound checks or follow-up evaluations.

• Ensure the documentation clearly specifies a chemical burn (corrosion) and not a thermal burn.
• Verify that the encounter is for a subsequent visit, not the initial treatment of the injury.
• Confirm the burn is explicitly located on the nasal septum and is classified as first-degree.
