Corrosion of second degree of left lower leg, sequela

This code signifies a second-degree chemical burn, often referred to as a corrosion, affecting the lower portion of the left leg. It indicates that the injury is no longer acute but has left a lasting effect or complication that requires ongoing care or evaluation. This type of burn involves the epidermis and dermis, causing blistering and significant pain.

This code is appropriate for documenting the long-term effects or complications arising from a second-degree chemical burn on the left lower leg. This could include scarring, persistent pain, limited range of motion, or other chronic issues directly attributable to the initial injury. It should be used when the patient is being seen for follow-up care related to these sequelae, not for the initial acute treatment.

• Always assign an external cause code (V00-Y99) in conjunction with this code to describe the circumstances of the injury.
• Do not use this code for initial encounters or active treatment of the acute burn; use the appropriate acute burn code for those scenarios.
• Ensure documentation clearly supports the "sequela" nature of the encounter, indicating ongoing issues from a past injury.
