Corrosion of second degree of unspecified foot, sequela

This code indicates a second-degree chemical burn (corrosion) on an unspecified foot, where the acute injury has healed, but residual effects or complications persist. A second-degree burn involves damage to the epidermis and dermis, typically presenting with blistering, pain, and redness. The "sequela" designation signifies that this code is used for the long-term consequences of such an injury.

Use this code when documenting a patient presenting with ongoing issues directly related to a past second-degree chemical burn on the foot. This could include chronic pain, scarring, contractures, or nerve damage that developed as a result of the original injury. It is appropriate for follow-up encounters after the initial healing phase.

• Always assign an external cause code (V00-Y99) to describe the circumstances of the corrosion.
• Do not use this code for acute or active second-degree chemical burns; instead, use the appropriate acute corrosion code.
• Ensure documentation clearly supports the "sequela" nature of the condition, indicating a residual effect rather than an active injury.
