Lesion of plantar nerve, right lower limb

This code signifies a pathological alteration or injury affecting the plantar nerve in the right lower extremity. This can manifest as nerve compression, entrapment, inflammation, or other forms of damage, leading to symptoms such as pain, numbness, tingling, or weakness in the sole of the right foot.

Use this code when documentation clearly indicates a lesion or dysfunction of the plantar nerve specifically affecting the right lower limb. This diagnosis is supported by findings from neurological examinations, nerve conduction studies, electromyography, or imaging that localize the pathology to the right plantar nerve.

• Specify laterality: Ensure documentation clearly states "right lower limb" to support this specific code.
• Distinguish from other neuropathies: Differentiate from more generalized peripheral neuropathies or other specific nerve entrapments in the foot (e.g., tarsal tunnel syndrome if the posterior tibial nerve is affected more proximally).
• Look for underlying cause: If an underlying cause for the lesion is identified (e.g., trauma, tumor, systemic disease), code it as a secondary diagnosis.
