Superficial frostbite of left wrist, sequela

This code signifies the long-term effects or complications arising from a superficial frostbite injury to the left wrist. It indicates that the initial frostbite has healed, but the patient is still experiencing residual issues directly attributable to that past injury.

Apply this code when documenting a patient presenting with a current condition, such as chronic pain, numbness, skin discoloration, or sensitivity, that is a direct result of a previously sustained superficial frostbite to their left wrist. This code is appropriate for follow-up encounters addressing these persistent sequelae.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., chronic pain).
• Ensure documentation clearly links the current condition to the prior superficial frostbite of the left wrist.
• The "S" in the 7th character indicates sequela and should be used for complications or conditions that arise as a direct result of an injury, after the acute phase has passed.
