Corrosion of unspecified degree of left palm, sequela

This code signifies a long-term complication or late effect resulting from a chemical burn to the palm of the left hand, where the initial degree of the burn was not specified. It indicates that the patient is presenting for treatment of a residual condition directly attributable to a past corrosive injury.

Use this code when documenting a patient encounter for ongoing issues such as scarring, contracture, chronic pain, or functional impairment of the left palm that developed as a consequence of a prior chemical burn. This applies when the original acute injury has healed, but its lasting effects are being addressed.

• Always ensure the documentation clearly links the current condition to a previous corrosive injury of the left palm.
• This "S" (sequela) encounter code should be used for subsequent visits after the initial acute injury has resolved.
• Code any specific sequelae (e.g., scar, contracture) in addition to this code to provide a complete clinical picture.
