Frostbite with tissue necrosis of left toe(s), sequela

This code signifies a long-term complication or late effect resulting from a previous frostbite injury to the left toe(s) that involved tissue death. The necrosis is not an acute process but rather a residual condition or consequence of the initial frostbite event.

Use this code when documenting a patient presenting with ongoing issues directly attributable to a past frostbite injury of the left toe(s) where tissue necrosis occurred. This includes conditions like chronic pain, non-healing ulcers, or deformities stemming from the necrotic tissue. It is appropriate for follow-up visits addressing these lasting effects, not the initial acute frostbite episode.

• Always sequence this code after the code for the specific sequela being treated (e.g., chronic pain, non-healing ulcer).
• Ensure documentation clearly links the current condition to a past frostbite injury with tissue necrosis of the left toe(s).
• Do not use for acute frostbite; this code is exclusively for sequelae.
