Lesion of plantar nerve

This code signifies a non-specific lesion or disorder affecting the plantar nerves of the foot. It encompasses various conditions causing pain, numbness, tingling, or weakness in the sole of the foot due to nerve involvement. This diagnosis indicates a problem with the nerve itself, rather than a systemic neuropathy.

Use this code when documentation specifies a lesion, entrapment, or other non-traumatic disorder of the plantar nerve(s) without further specificity. This is appropriate for conditions like plantar fasciitis with nerve involvement, Morton's neuroma (prior to specific ICD-9-CM codes for neuroma), or other idiopathic plantar nerve compressions. Supporting documentation would include physician notes detailing symptoms localized to the plantar aspect of the foot and attributing them to nerve pathology.

• This is a general code; look for more specific ICD-9-CM codes if the type of lesion (e.g., neuroma, entrapment) is clearly documented.
• Differentiate from systemic neuropathies (e.g., diabetic neuropathy), which would be coded elsewhere.
• Ensure documentation clearly links symptoms to a plantar nerve lesion and not solely to musculoskeletal issues like plantar fasciitis without nerve involvement.
