Code Classification

  • Diseases of the nervous system
    (G00–G99)
    • Nerve, nerve root and plexus disorders
      (G50-G59)
      • Mononeuropathies of lower limb
        (G57)

G57.50 is a billable diagnosis code used to specify a medical diagnosis of tarsal tunnel syndrome, unspecified lower limb. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like G57.50 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

Clinical Classification

Clinical Information

  • Tarsal Tunnel Syndrome

    entrapment of the distal branches of the posterior tibial nerve (which divides into the medial plantar, lateral plantar, and calcanial nerves) in the tarsal tunnel, which lies posterior to the internal malleolus and beneath the retinaculum of the flexor muscles of the foot. symptoms include ankle pain radiating into the foot which tends to be aggravated by walking. examination may reveal tinel's sign (radiating pain following nerve percussion) over the tibial nerve at the ankle, weakness and atrophy of the small foot muscles, or loss of sensation in the foot. (from foot ankle 1990;11(1):47-52)

  • Tibial Nerve

    the medial terminal branch of the sciatic nerve. the tibial nerve fibers originate in lumbar and sacral spinal segments (l4 to s2). they supply motor and sensory innervation to parts of the calf and foot.

  • Tarsal Tunnel Syndrome

    a syndrome resulting from the entrapment and compression of the tibial nerve. signs and symptoms include burning sensation, tingling, and pain in the foot sole.

Convert G57.50 to ICD-9-CM
