Within G65 (sequelae of inflammatory and toxic polyneuropathies), G65.0 is specifically for sequelae of Guillain-Barre syndrome. Related codes cover other inflammatory polyneuropathy (G65.1) and toxic polyneuropathy (G65.2).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
