Corrosion of first degree of right forearm, sequela

This code signifies the long-term effects or complications arising from a first-degree corrosion (chemical burn) on the right forearm. It indicates that the initial injury has healed, but residual issues, such as scarring, pigment changes, or chronic pain, are still present and being addressed.

Apply this code when documenting follow-up care for a patient whose right forearm previously sustained a first-degree chemical burn, and they are now presenting with a condition directly attributable to that past injury. This includes scenarios where the patient is being treated for a scar revision, persistent discoloration, or nerve irritation resulting from the original corrosion.

• Always use an additional code to specify the exact nature of the sequela (e.g., L90.5 for scar conditions).
• Ensure documentation clearly links the current condition to the past chemical burn of the right forearm.
• This code is for residual effects, not for the initial treatment of the acute burn.
