Immersion foot, unspecified foot, sequela

This code signifies the long-term effects or complications arising from immersion foot (trench foot) in an unspecified foot. These sequelae can include chronic pain, numbness, hypersensitivity, skin changes, or circulatory issues that persist after the acute phase of the injury has resolved. It indicates that the original immersion foot injury is no longer active but has left lasting consequences.

Use this code when documenting a patient presenting with ongoing symptoms directly attributable to a past episode of immersion foot, where the specific foot affected (left or right) is not documented. This applies to follow-up visits for chronic conditions resulting from the original injury, such as persistent neuropathy or trophic changes.

• Only use this code for the sequela of immersion foot, not the acute injury.
• Ensure documentation clearly links the current symptoms to a prior immersion foot episode.
• If the specific foot (left or right) is documented, a more specific sequela code should be used.
