Corrosion of first degree of right thigh, sequela

This code signifies a permanent scar, contracture, or other long-term complication resulting from a first-degree corrosion (chemical burn) that occurred on the patient's right thigh. First-degree corrosions involve only the epidermis, causing redness and mild pain, but the sequela indicates a lasting effect beyond the initial healing phase.

Assign this code when documenting a patient presenting with a chronic condition directly attributable to a past first-degree chemical burn on their right thigh. This could include scar tissue, changes in skin pigmentation, or persistent sensitivity in the affected area. It is used when the acute injury has healed, but its lasting effects are being treated or evaluated.

• Always sequence this code after the primary diagnosis for the current condition being treated.
• Ensure documentation clearly links the current sequela to a previous first-degree corrosion of the right thigh.
• Do not use this code for acute chemical burns; it is exclusively for residual effects.
