Within G54 (nerve root and plexus disorders), G54.5 is specifically for Neuralgic amyotrophy.

Don't report G54.5 together with the conditions in its Excludes1 note: neuralgic amyotrophy in diabetes mellitus (E08-E13 with .44).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
