Corrosion of unspecified degree of unspecified palm, sequela

This code signifies the long-term effects or complications resulting from a chemical burn of an unspecified degree to an unspecified palm. It indicates that the acute injury has healed, but residual issues, such as scarring, contractures, or chronic pain, are still present.

Apply this code when documenting a patient presenting for follow-up care or treatment of a permanent complication directly attributable to a past chemical burn of the palm. This is appropriate when the initial acute injury has resolved, and the current encounter addresses the sequelae.

• Always use this 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 previous chemical burn of the palm.
• Avoid using this code for acute chemical burns; use the appropriate acute burn codes instead.
