About coding monoplegia
The ICD-10-CM code for monoplegia is G83.3 (Monoplegia, unspecified). The official index lists 23 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on G83.3.
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.
