Corros 2nd deg of unsp site right low limb, ex ank/ft, sqla

This code indicates a lasting complication or late effect resulting from a second-degree chemical burn (corrosion) on the right lower limb, excluding the ankle and foot. The original injury has healed, but residual issues persist.

Apply this code when documenting conditions such as scarring, contractures, chronic pain, or nerve damage that are directly attributable to a past second-degree chemical burn on the specified area of the right lower limb. This code is appropriate when the acute phase of the burn has resolved, and the patient is presenting for treatment of these long-term consequences.

• Always use an external cause code (V00-Y99) in conjunction with this code to fully describe the circumstances of the original corrosion.
• Ensure the documentation clearly links the current sequela to a prior second-degree chemical burn of the right lower limb (excluding ankle/foot).
• Do not use this code for active or acute burn treatment; it is exclusively for late effects.
