Corros 2nd deg mul left fingers (nail), inc thumb, sequela

This code signifies the long-term effects or complications arising from a second-degree chemical burn affecting multiple fingers, including the thumb, on the patient's left hand. The burn specifically involves the nail or nail bed area. These sequelae could include scarring, nail deformities, chronic pain, or functional limitations that persist after the initial injury has healed.

This code is appropriate when documenting a patient presenting with residual problems or late effects directly attributable to a past second-degree chemical burn of the specified left fingers. It should be used for follow-up encounters where the primary focus is managing these chronic conditions, not the acute burn itself. Examples include ongoing treatment for nail dystrophy or pain management related to the healed burn.

• Always assign an external cause code (V00-Y99) to describe the circumstances of the original injury, if known.
• Ensure the documentation clearly links the current condition to the previous chemical burn as a sequela.
• Do not use this code for acute or active second-degree chemical burns; instead, use the appropriate acute burn code from the T23 category.
