Injury of medial plantar nerve, right leg, sequela

This code signifies a lasting or residual effect from a past injury to the medial plantar nerve in the right foot. This nerve is crucial for sensation and motor function in the arch and toes, and its sequelae can manifest as chronic pain, numbness, tingling, or weakness in the affected area.

Use this code when documenting a current condition that is a direct consequence of an old injury to the right medial plantar nerve, and the acute phase of the original injury has passed. This is appropriate for patients presenting with persistent symptoms such as chronic neuropathy, paresthesia, or muscle atrophy in the right foot, directly attributable to a prior medial plantar nerve trauma.

• Requires a seventh character 'S' to indicate sequela, meaning the residual effect of a past injury.
• Do not use for acute injuries; a different code from the S94.11- category would be appropriate for the initial encounter.
• Ensure documentation clearly links the current symptoms to a previously sustained injury of the right medial plantar nerve.
