Superficial frostbite of unspecified finger(s), sequela

This code signifies a permanent or long-term complication resulting from a superficial frostbite injury to an unspecified finger. It indicates that the initial frostbite has resolved, but the patient is now experiencing a residual effect such as chronic pain, numbness, or hypersensitivity in the affected digit.

Apply this code when documenting a patient presenting with a sequela directly attributable to a past superficial frostbite of any finger, where the acute injury has healed. This is appropriate for follow-up visits addressing ongoing issues like nerve damage or circulatory problems stemming from the original frostbite.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, paresthesia).
• Ensure documentation clearly links the current condition to a previous superficial frostbite of the finger.
• The "S" at the end indicates a sequela; do not use this code for the initial acute frostbite injury.
