Corros second degree of single l finger except thumb, subs

This code signifies a second-degree chemical burn affecting a single finger on the left hand, excluding the thumb, that is being treated after the initial encounter. This type of injury involves damage to the epidermis and dermis, often presenting with blistering and significant pain.

Apply this code when documenting follow-up care for a patient who sustained a second-degree chemical burn to a left finger (not the thumb). This includes scenarios such as wound checks, dressing changes, or management of complications arising from the initial corrosion.

• Ensure the documentation specifies a chemical burn (corrosion) rather than a thermal burn.
• Verify that the encounter is for subsequent care, not the initial treatment of the injury.
• Confirm the affected digit is a single left finger and not the thumb.
