Burn of first degree of right knee, sequela

This code signifies a first-degree burn affecting the right knee, where the acute injury has healed, but residual effects or complications persist. These sequelae might include scarring, changes in skin pigmentation, or chronic pain directly attributable to the original burn. It indicates that the burn is no longer an active, acute injury but has left lasting consequences.

Use this code when documenting follow-up care for a patient whose right knee sustained a first-degree burn in the past, and they are now presenting with a condition directly resulting from that healed burn. This applies to situations where the initial burn treatment is complete, and the focus is on managing the long-term effects. Examples include evaluating a scar contracture or persistent discoloration from the original burn.

• Always assign 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 links the current condition to the previous first-degree burn of the right knee.
• Do not use this code for acute burns; use the appropriate acute burn code for initial encounters.
