About G83.3

G83.3 is the ICD-10-CM diagnosis code for monoplegia, unspecified. It belongs to category G83 (other paralytic syndromes), block G80-G83 (cerebral palsy and other paralytic syndromes) and chapter 6 (diseases of the nervous system). It is a header code, so it can't be reported by itself; one of its 5 subcodes must be used instead.

Within G83, choose G83.3 (Monoplegia, unspecified) only when documentation doesn't support a more specific option: diplegia of upper limbs (G83.0), monoplegia of lower limb (G83.1), monoplegia of upper limb (G83.2), cauda equina syndrome (G83.4), Locked-in state (G83.5), other specified paralytic syndromes (G83.8) and paralytic syndrome, unspecified (G83.9).

To report this condition, pick the subcode that matches the documentation: G83.30 (affecting unspecified side), G83.31 (affecting right dominant side), G83.32 (affecting left dominant side), G83.33 (affecting right nondominant side) and G83.34 (affecting left nondominant side).

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