Corrosion of second degree of left hand, unsp site, sequela

This code indicates a healed or chronic second-degree corrosion injury affecting an unspecified area of the left hand. Corrosion, often caused by chemical exposure, results in tissue damage that extends through the epidermis and into the dermis, characterized by blistering and significant pain. The "sequela" designation signifies that this code is used for the late effects or complications of such an injury, not the acute event itself.

Use this code when documenting the long-term consequences or residual conditions stemming from a second-degree chemical burn to the left hand. This includes issues like scarring, contractures, chronic pain, or functional limitations that persist after the initial healing phase of the corrosion. It is appropriate for follow-up encounters addressing these lasting effects.

• Always ensure documentation clearly specifies the left hand and the second-degree nature of the original corrosion.
• Confirm that the encounter is for a late effect or complication, not the initial treatment of the acute injury.
• Consider additional codes for specific sequelae, such as scar formation (e.g., L90.5) or contracture (e.g., M24.542), if detailed in the medical record.
