Burn of first degree of unspecified knee, sequela

This code signifies a first-degree burn affecting an unspecified knee, indicating superficial skin damage without blistering or deeper tissue involvement. The "S" suffix denotes that this is a sequela, meaning the code is used for complications or conditions arising as a direct result of the initial burn injury, even after the acute phase has passed.

Apply this code when documenting the long-term effects or complications stemming from a previously sustained first-degree burn to the knee. This could include chronic pain, scarring, or other persistent issues directly attributable to the original burn. It is not for the initial acute burn treatment.

• Always assign an external cause code (V00-Y99) in conjunction with sequela codes to describe the circumstances of the original injury.
• Ensure documentation clearly links the current condition to the prior first-degree knee burn to support the sequela designation.
• Do not use this code for acute first-degree burns; instead, use the appropriate acute burn code from the T20-T25 range.
