Corrosion of first degree of back of unsp hand, subs encntr

This code signifies a first-degree burn, specifically a corrosion, affecting the dorsal aspect of an unspecified hand. A first-degree burn involves only the epidermis, presenting with redness, pain, and no blistering. Corrosion indicates a chemical burn rather than thermal.

Apply this code when documenting follow-up care for a patient who previously sustained a chemical burn of the first degree to the back of their hand. This would include subsequent visits for wound checks, dressing changes, or monitoring healing progress. It is appropriate for encounters after the initial treatment of the injury.

• Ensure the documentation clearly specifies a chemical burn (corrosion) and not a thermal burn.
• Verify that the encounter is for follow-up care, not the initial treatment, to justify the "D" seventh character.
• Confirm the burn location is explicitly the "back of the hand" and the degree is "first degree."
