G81 vs I69.05
G81 (Hemiplegia and hemiparesis) compared with I69.05 (Hemiplegia and hemiparesis following nontraumatic subarachnoid hemorrhage), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. G81 carries an Excludes1 note covering I69.05: “hemiplegia and hemiparesis due to sequela of cerebrovascular disease (I69.05-, I69.15-, I69.25-, I69.35-, I69.85-, I69.95-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
