Corrosion of second degree of left ankle, sequela

This code signifies a past second-degree burn injury to the left ankle, where the acute injury has healed but residual effects or complications persist. These sequelae could include scarring, contractures, chronic pain, or other long-term consequences directly attributable to the original burn.

Apply this code when documenting and billing for treatment of conditions that are direct results of a second-degree corrosion (chemical burn) to the left ankle, occurring after the initial healing phase. This is appropriate for follow-up care, rehabilitation, or management of chronic issues stemming from the original injury.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., scar, contracture).
• Ensure documentation clearly links the current condition to the previous second-degree corrosion of the left ankle.
• Do not use for acute burns; this code is exclusively for long-term effects.
