Superficial frostbite of left finger(s), sequela

This code indicates a long-term complication or residual effect stemming from a superficial frostbite injury to one or more fingers on the left hand. These sequelae might include persistent numbness, hypersensitivity to cold, chronic pain, or changes in skin texture or color that remain after the initial frostbite has healed.

Apply this code when documenting a patient presenting with a current, ongoing condition directly attributable to a past superficial frostbite injury of the left finger(s). This is appropriate for follow-up encounters addressing these lasting effects, rather than the acute injury itself.

• Requires a seventh character 'S' to denote sequela, indicating a complication or residual effect of a past injury.
• Do not use for acute frostbite; this code is specifically for the late effects.
• Code any specific manifestations of the sequela (e.g., chronic pain) in addition to this code, if applicable.
