Corros first degree of unsp single finger except thumb, init

This code signifies a superficial burn, specifically a first-degree corrosion, affecting a single finger other than the thumb. It indicates damage limited to the outermost layer of the skin, characterized by redness and mild pain, without blistering or deeper tissue involvement. The "nail" in the description clarifies that the injury may involve the nail unit of the affected finger.

Apply this code when documenting a first-degree chemical burn to any single finger (excluding the thumb) during the initial treatment phase. This would include instances where a patient presents with a red, painful finger after contact with a corrosive substance, and it's their first time seeking care for this specific injury.

• Ensure the documentation clearly specifies a first-degree burn and a corrosive agent as the cause.
• Verify that the injury is to a single finger and not the thumb; if the thumb is involved, a different code is required.
• The "A" at the end signifies an initial encounter, meaning this code is only used for the first time the patient is seen for this specific injury.
