ICD-10 Code G57.53 – Tarsal tunnel syndrome, bilateral lower limbs (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G57.53 – Tarsal tunnel syndrome, bilateral lower limbs
What it is
G57.53 identifies compression of the tibial nerve in both tarsal tunnels, causing a peripheral nerve entrapment in the ankles. Use it when the record specifically documents bilateral involvement.
Clinical signs
Typical findings include burning, tingling, numbness, or pain along the plantar foot and toes, often worse with standing or walking. Exam may show tenderness over the tarsal tunnel or a positive Tinel sign. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents bilateral tarsal tunnel syndrome, tibial nerve entrapment at the ankle on both sides, or similar wording. It is appropriate for confirmed diagnoses in outpatient, inpatient, or specialty notes. If laterality is not stated, check documentation.
Do not use for
Do not use G57.53 for unilateral tarsal tunnel syndrome or for nonspecific foot pain without a documented nerve entrapment diagnosis. If the note only says neuropathy or paresthesia, check documentation for a more precise diagnosis.
Coding tip
Capture laterality exactly as documented, because this code is specific to bilateral lower limbs.
