Corrosion of second degree of right thigh, sequela

This code indicates a second-degree chemical burn (corrosion) affecting the right thigh, where the acute injury has healed and the patient is now presenting for treatment of a residual condition or complication directly resulting from that burn. This could include scarring, contractures, chronic pain, or other long-term effects.

Apply this code when documenting or billing for services related to the long-term consequences or late effects of a second-degree chemical burn to the right thigh. This is appropriate for follow-up visits addressing scar revision, physical therapy for contractures, or management of chronic pain directly attributable to the original corrosion.

• Always use this "S" (sequela) seventh character when the patient is being seen for complications or residual conditions of a healed burn.
• Do not use this code for the initial treatment of the acute burn; use an acute burn code (e.g., T24.211A) for that phase.
• Consider additional codes for specific sequelae, such as L90.5 for scar conditions or M24.5 for contractures, to provide a complete clinical picture.
