Corrosion of first degree of left axilla, subs encntr

This code indicates a superficial burn, specifically a first-degree corrosion, affecting the left armpit area. A first-degree burn involves only the outermost layer of skin (epidermis), typically presenting with redness, mild swelling, and pain, but no blistering or open wounds. "Corrosion" implies the burn was caused by a chemical agent.

Use this code for follow-up encounters or subsequent care for a patient whose left axilla sustained a first-degree chemical burn. This applies after the initial treatment of the acute injury. Examples include wound checks, dressing changes, or evaluation of healing progress.

• Ensure the documentation specifies "corrosion" (chemical burn) and not a thermal burn.
• Verify the encounter is for subsequent care, not the initial treatment.
• Confirm the burn is explicitly documented as first-degree and located on the left axilla.
