Corrosion of first deg mult sites of left wrs/hnd, sequela

This code signifies the long-term effects or complications arising from a first-degree corrosion (e.g., chemical burn) that affected multiple areas of the left wrist and hand. It indicates that the initial injury has healed, but there are residual issues or conditions directly attributable to that past corrosion.

Use this code when documenting a patient presenting with a current condition that is a direct consequence of a previously sustained first-degree chemical burn to multiple sites on their left wrist and hand. This applies when the acute phase of the burn has resolved, and the current encounter addresses a chronic or late effect, such as scarring, altered sensation, or functional limitations.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., scar, contracture).
• Ensure documentation clearly links the current condition to the past first-degree corrosion of the left wrist and hand.
• Verify that the corrosion was explicitly stated as first-degree and involved multiple sites of the specified anatomy.
