Corrosion of second degree of neck, sequela

This code signifies the long-term effects or complications arising from a second-degree chemical burn (corrosion) on the neck. These sequelae could include scarring, contractures, chronic pain, or other persistent issues that manifest after the initial injury has healed. It indicates that the original burn event is no longer acute, but its lasting impact is being addressed.

Use this code when documenting a patient encounter for the management of chronic conditions directly resulting from a second-degree chemical burn to the neck. This applies to follow-up visits where the focus is on treating the residual effects, rather than the initial acute injury. Examples include surgical revision of scar tissue or ongoing physical therapy for limited range of motion due to a neck contracture.

• Always use an additional code to identify the specific sequela, such as a scar (L90.5) or contracture (M24.58).
• This code is for chemical burns only; thermal burns would use a different category (T20.2 or T20.3).
• The "S" in the 7th character indicates sequela and should be used for complications or conditions that arise as a direct result of the initial injury.
