G57.40 is a billable diagnosis code used to specify a medical diagnosis of lesion of medial popliteal nerve, 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 G57.40 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.

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 Neuropathy
disease of the tibial nerve (also referred to as the posterior tibial nerve). the most commonly associated condition is the tarsal tunnel syndrome. however, leg injuries; ischemia; and inflammatory conditions (e.g., collagen diseases) may also affect the nerve. clinical features include paralysis of plantar flexion, ankle inversion and toe flexion as well as loss of sensation over the sole of the foot. (from joynt, clinical neurology, 1995, ch51, p32)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.
