Inj deep peroneal nrv at ank/ft level, left leg, sequela

This code signifies a lasting neurological deficit or complication resulting from a previous injury to the deep peroneal nerve in the left ankle or foot region. This could manifest as chronic weakness, numbness, or altered sensation in the dorsum of the foot or toes, affecting the patient's ability to dorsiflex the foot or extend the toes. The "sequela" aspect indicates that the initial acute injury has resolved, but its effects persist.

Use this code when documenting a patient presenting with ongoing symptoms directly attributable to a past injury of the deep peroneal nerve in the left ankle or foot. This applies to conditions like chronic foot drop, persistent paresthesia, or muscle atrophy in the affected area, where the original injury is no longer acute but its consequences remain.

• Ensure documentation clearly states the left leg and the "sequela" nature of the condition, indicating a resolved acute injury with persistent effects.
• Always code the underlying cause of the original injury if known and still relevant for medical necessity or treatment.
• Do not use this code for acute injuries; instead, refer to the acute injury codes within the S94 category.
