Superficial frostbite of unspecified toe(s), sequela

This code indicates that a patient is experiencing a current health condition or complication that is a direct result of a superficial frostbite injury to an unspecified toe or toes that occurred in the past. The original frostbite event is no longer active, but its lasting effects are being addressed.

Use this code when documenting follow-up care for a patient presenting with residual symptoms or long-term complications stemming from a previously treated superficial frostbite of the toe(s). Examples include ongoing pain, numbness, skin discoloration, or sensitivity in the affected toe(s) after the acute phase of frostbite has resolved.

• Always use this code as a secondary diagnosis, following the code for the current condition being treated.
• Ensure documentation clearly links the current toe-related issue to a past superficial frostbite event.
• Avoid using this code for acute frostbite; instead, use the appropriate acute frostbite code from the T33 category.
