ICD-10 Code G57.52 – Tarsal tunnel syndrome, left lower limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G57.52 – Tarsal tunnel syndrome, left lower limb
What it is
G57.52 identifies compression of the posterior tibial nerve in the left tarsal tunnel. Use it when the record specifies tarsal tunnel syndrome affecting the left lower limb.
Clinical signs
Typical findings include pain, burning, tingling, or numbness along the plantar foot, sometimes worse with standing or walking. Clinical features vary; refer to documentation.
When to use this code
Use G57.52 when the clinician documents tarsal tunnel syndrome on the left side, including suspected or confirmed nerve entrapment at the ankle. It is appropriate when laterality is clearly stated. If the note only says “tarsal tunnel syndrome” without side, check documentation.
Do not use for
Do not use this code for right-sided or unspecified tarsal tunnel syndrome. Do not assign it for other causes of foot pain or neuropathy unless the record specifically documents left tarsal tunnel syndrome.
Coding tip
Always confirm laterality in the assessment or impression before assigning G57.52.
