Superficial frostbite of left foot, sequela

This code signifies a long-term complication or residual effect stemming from a superficial frostbite injury to the left foot. It indicates that the initial frostbite has healed, but there are lasting issues directly attributable to that injury, such as persistent numbness, hypersensitivity, or altered skin texture.

This code is appropriate for documenting follow-up encounters where a patient presents with ongoing symptoms or conditions in their left foot that are a direct consequence of a previously sustained superficial frostbite. It should be used when the acute phase of the frostbite has resolved, and the current treatment addresses these chronic sequelae.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, neuropathy).
• Ensure documentation clearly links the current condition in the left foot to a past superficial frostbite injury.
• Do not use this code for the initial or acute treatment of superficial frostbite; use an acute frostbite code for that phase.
