Burn of second degree of scalp [any part], sequela

This code signifies a second-degree burn affecting any part of the scalp, where the acute injury has healed but residual effects or complications persist. These sequelae might include scarring, hair loss (alopecia), changes in skin pigmentation, or chronic pain related to the original burn.

Apply this code when documenting a patient presenting for treatment of a long-term complication or residual condition directly resulting from a previously sustained second-degree scalp burn. This is appropriate for follow-up visits addressing the chronic impact of the burn, not the initial acute injury.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., L90.5 for scar conditions).
• Ensure documentation clearly states the burn was second-degree and located on the scalp, and that the current encounter addresses a sequela.
• Do not use for acute burn treatment; instead, use the appropriate T20.2- code without the 'S' seventh character.
