Burn of third degree of nose (septum), sequela

This code signifies a third-degree burn affecting the nose, specifically the septum, where the acute injury has healed and residual effects or complications are being treated. Third-degree burns involve full-thickness destruction of the skin and underlying tissue, often resulting in scarring, contractures, or functional impairment. The "sequela" designation indicates that the current encounter addresses a long-term consequence of the original burn.

Use this code when a patient presents for treatment of a complication or late effect directly attributable to a previously sustained third-degree burn of the nasal septum. This includes scenarios such as reconstructive surgery for severe scarring, management of chronic pain, or addressing respiratory obstruction due to septal deformity caused by the burn. It should be applied after the initial acute burn treatment has concluded.

• Always use this code as a secondary diagnosis, following a primary code that describes the specific sequela being treated (e.g., scar, contracture).
• Ensure documentation clearly links the current condition to the past third-degree burn of the nasal septum.
• Verify that the "S" seventh character is appropriate, indicating sequela, and not an active burn or subsequent encounter for initial healing.
