About coding wrist paralysis

The ICD-10-CM code for wrist paralysis is G56.9 (Unspecified mononeuropathy of upper limb).

Within G56, choose G56.9 (Unspecified mononeuropathy of upper limb) only when documentation doesn't support a more specific option: carpal tunnel syndrome (G56.0), other lesions of median nerve (G56.1), lesion of ulnar nerve (G56.2), lesion of radial nerve (G56.3), Causalgia of upper limb (G56.4) and other specified mononeuropathies of upper limb (G56.8).

To report this condition, pick the subcode that matches the documentation: G56.90 (limb), G56.91 (limb), G56.92 (limb) and G56.93 (limbs).

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