About coding hemiplegia
The ICD-10-CM code for hemiplegia is G81.9 (Hemiplegia, unspecified). The official index lists 20 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on G81.9.
Within G81, choose G81.9 (Hemiplegia, unspecified) only when documentation doesn't support a more specific option: flaccid hemiplegia (G81.0) and spastic hemiplegia (G81.1).
To report this condition, pick the subcode that matches the documentation: G81.90 (affecting unspecified side), G81.91 (affecting right dominant side), G81.92 (affecting left dominant side), G81.93 (affecting right nondominant side) and G81.94 (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.
