Superficial frostbite of left hand, sequela

This code signifies a lasting health problem or condition resulting from a superficial frostbite injury to the left hand. It indicates that the initial frostbite has resolved, but the patient is experiencing a residual effect, such as chronic pain, numbness, or altered sensation, directly attributable to that past injury.

Use this code when documenting a patient presenting with a current complaint or condition that is a direct consequence of a previously sustained superficial frostbite to their left hand. This applies to follow-up encounters where the acute frostbite has healed, but its long-term impact is being addressed.

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