Corros second degree of unsp mult fngr, inc thumb, subs

This code signifies a second-degree chemical burn affecting multiple, unspecified fingers, including the thumb. A second-degree corrosion involves damage to the epidermis and dermis, characterized by blistering, pain, and redness. This particular code is for a subsequent encounter, meaning the patient is receiving follow-up care for an injury that has already been initially treated.

Use this code for follow-up visits where a patient is being treated for a second-degree chemical burn to several fingers, including the thumb, and the specific fingers affected are not documented. This applies to scenarios such as wound care, dressing changes, or re-evaluation of the healing process after the initial treatment. It is appropriate when the initial injury has already been coded with a corresponding initial encounter code.

• Ensure documentation clearly states "subsequent encounter" for this specific injury.
• Verify the burn is explicitly described as a "corrosion" (chemical burn) and not a thermal burn.
• Confirm the burn involves multiple fingers, including the thumb, and the specific digits are not detailed.
