Corrosion of first degree of left thumb (nail), subs encntr

This code signifies a first-degree burn, specifically a superficial injury affecting the outermost layer of skin, on the left thumb, including the nail area. This type of burn typically presents with redness and mild pain but no blistering.

This code is appropriate for documenting follow-up care for a first-degree corrosion of the left thumb or its nail. This includes situations where the patient is returning for wound checks, dressing changes, or evaluation of healing progress after the initial treatment.

• Ensure the documentation clearly specifies "left thumb" and "first degree" for accurate code assignment.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing phase.
• Verify that the injury is indeed a corrosion (chemical burn) and not a thermal burn, as different code categories apply.
