ICD-10 code for thigh paralysis

The ICD-10-CM code for thigh paralysis is G57.9 (Unspecified mononeuropathy of lower limb).

Within G57, choose G57.9 (Unspecified mononeuropathy of lower limb) only when documentation doesn't support a more specific option: lesion of sciatic nerve (G57.0), Meralgia paresthetica (G57.1), lesion of femoral nerve (G57.2), lesion of lateral popliteal nerve (G57.3), lesion of medial popliteal nerve (G57.4), tarsal tunnel syndrome (G57.5), lesion of plantar nerve (G57.6), Causalgia of lower limb (G57.7) and 1 more.

To report this condition, pick the subcode that matches the documentation: G57.90 (limb), G57.91 (limb), G57.92 (limb) and G57.93 (limbs).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
