Corrosion of unspecified degree of left wrist, sequela

This code signifies the long-term effects or complications arising from a past corrosive injury (e.g., chemical burn) to the left wrist, where the original degree of the burn was not specified. It indicates that the patient is currently experiencing residual problems directly attributable to that previous corrosive exposure.

Use this code when documenting conditions such as scarring, contractures, chronic pain, or functional limitations in the left wrist that are a direct consequence of a resolved corrosive burn. This code is appropriate for encounters where the initial injury has healed, but its lasting impact is being addressed.

• Always sequence this "S" code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., scar, contracture).
• Ensure documentation clearly links the current condition to a past corrosive injury of the left wrist.
• Do not use this code for acute corrosive injuries; those require codes from the initial encounter or subsequent encounter categories.
