This ICD-10-CM code is used to classify a second-degree burn, or corrosion, affecting multiple left fingers (nail), excluding the thumb, during an initial encounter with the healthcare system.
Code Application Guidance
- Code first (T51-T65) to identify chemical and intent.
- Use additional external cause code to identify the place (Y92).
Use Cases
1. Scenario: A patient presents to the emergency department after accidentally spilling a chemical solution onto their left index and middle finger, resulting in blistering and epidermal loss. The thumb is unaffected.
Code: T23.632A
External Cause Code Example: Y92.0 - While at work, unspecified.
2. Scenario: A 10-year-old child is brought to the clinic after burning their left ring and pinky finger with hot water. Blisters are present, indicating a second-degree burn.
Code: T23.632A
External Cause Code Example: Y92.8 - While playing, unspecified.
3. Scenario: An adult presents to a dermatology clinic with a history of contact dermatitis on their left middle and ring fingers. Upon examination, the physician determines that the dermatitis is likely due to prolonged exposure to a harsh hand cleaner, resulting in a corrosive injury.
