Corrosion of first degree of unspecified thigh, sequela

This code signifies the long-term effects or complications arising from a first-degree corrosion (chemical burn) that occurred on an unspecified part of the thigh. It indicates that the initial injury has healed, but residual issues or conditions related to that burn are still present and require ongoing management.

This code is appropriate when documenting a patient presenting with a current condition directly attributable to a previously sustained first-degree chemical burn of the thigh. Examples include persistent scarring, pigmentation changes, or chronic sensitivity in the affected area, long after the acute phase of the burn has resolved.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the prior first-degree corrosion of the thigh.
• Avoid using this code for acute or active first-degree chemical burns; those require codes from the acute burn section.
