Other and unspecified encephalopathy

Not billableICD-10-CM diagnosis code.

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2016 onwards. It has never been valid for submission on its own.

Submit one of these 7 more specific codes instead:

G93.40 Encephalopathy, unspecified
G93.41 Metabolic encephalopathy
G93.42 Megalencephalic leukoencephalopathy with subcortical cysts
G93.43 Leukoencephalopathy with calcifications and cysts
G93.44 Adult-onset leukodystrophy with axonal spheroids
G93.45 Developmental and epileptic encephalopathy
G93.49 Other encephalopathy

What has happened to this code

Every change the publisher made, from 2012 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.

FY2012 Added to the draft code set draft Other and unspecified encephalopathy
