ICD-10 Code G57.61 – Lesion of plantar nerve, right lower limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G57.61 – Lesion of plantar nerve, right lower limb
What it is
G57.61 identifies a disorder of the plantar nerve in the right lower limb. Use it when documentation specifies a lesion, irritation, or neuropathic involvement of that nerve on the right side.
Clinical signs
Typical findings include pain, numbness, tingling, or burning in the plantar foot distribution. Clinical features vary; refer to documentation, especially if the record names the right plantar nerve as the affected site.
When to use this code
Use G57.61 when the provider documents a lesion of the plantar nerve affecting the right lower limb, including neuralgia or neuropathy localized to that nerve. It is appropriate when the laterality is clearly stated as right. If the note only says foot pain or peripheral neuropathy without nerve specificity, check documentation.
Do not use for
Do not use this code for left-sided or unspecified plantar nerve lesions, or for general foot pain without nerve involvement. It is also not for traumatic nerve injury unless the documentation supports this diagnosis.
Coding tip
Verify both the nerve name and laterality in the provider note before assigning G57.61.
