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

This code signifies a past episode of frostbite affecting the right toe(s) that resulted in tissue death (necrosis). The "S" at the end indicates that this is a sequela code, meaning it's used to report a condition that is a late effect or complication of the initial frostbite injury.

This code is appropriate when a patient presents with a current condition or complication directly attributable to a previous frostbite injury of the right toe(s) that involved tissue necrosis. Examples include chronic pain, non-healing ulcers, or deformities stemming from the original necrotic frostbite. It should not be used for the initial acute frostbite episode.

• Always sequence this code after the code(s) for the specific current condition or complication being treated.
• Ensure documentation clearly links the current condition to a prior frostbite event of the right toe(s) with necrosis.
• Do not use this code for acute frostbite; a different code from the T33-T34 range would be appropriate for the initial injury.
