Corrosion of third degree of right lower leg, sequela

This code signifies a deep tissue injury to the right lower leg, specifically a third-degree burn or chemical corrosion, where the acute injury has healed and the patient is now presenting for treatment of a residual condition or complication. This could include scarring, contractures, chronic pain, or other long-term effects directly attributable to the initial severe corrosion.

Apply this code when documenting follow-up care for a patient whose right lower leg previously sustained a full-thickness burn or chemical corrosion, and they are now being treated for a sequela. This is appropriate for conditions like hypertrophic scarring requiring revision, persistent neuropathic pain, or functional limitations due to tissue damage that occurred months or years prior.

• Always use this code as a secondary diagnosis, following a code that describes the specific sequela being treated (e.g., a code for scar, contracture, or chronic pain).
• Ensure documentation clearly links the current condition to the past third-degree corrosion of the right lower leg.
• Do not use this code for initial treatment of an acute corrosion or for superficial or partial-thickness burns.
