Corrosion of second degree back of right hand, sequela

This code signifies a second-degree chemical burn, also known as corrosion, affecting the back of the patient's right hand. A second-degree burn involves damage to the epidermis and part of the dermis, typically presenting with blistering, pain, and redness. The "sequela" indicator denotes that this encounter is for the long-term effects or complications of a previously sustained corrosion.

This code is appropriate when a patient is being treated for a complication or residual condition directly resulting from a second-degree chemical burn to the back of their right hand that occurred in the past. Examples include scar contracture, chronic pain, or ongoing wound care for a non-healing area related to the original injury. It should not be used for the initial encounter or active treatment of the acute burn.

• Always assign an external cause code (V00-Y99) in conjunction with this code to describe the circumstances of the corrosion.
• Ensure documentation clearly states the burn was chemical (corrosion) and not thermal, and specifies the "sequela" nature of the encounter.
• Verify the laterality (right hand) and anatomical site (back of hand) are accurately documented to support this specific code.
