Immersion hand, right hand, sequela

This code signifies the long-term or residual effects of a cold injury, specifically non-freezing cold injury (NFCI) or immersion injury, affecting the right hand. These sequelae can include chronic pain, numbness, hypersensitivity, skin changes, or functional limitations that persist after the initial injury has healed.

Apply this code when documenting a patient presenting with ongoing symptoms or complications in their right hand directly attributable to a past immersion injury or trench foot. This is appropriate for follow-up visits addressing these chronic issues, rather than the acute injury itself.

• Always ensure documentation clearly links the current symptoms to a previous immersion injury of the right hand.
• This code is for sequelae; do not use it for the initial acute injury.
• Consider additional codes for specific chronic conditions (e.g., chronic pain, neuropathy) if sufficiently documented.
