Coma scale, best motor response, obeys commands

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 5 more specific codes instead:

R40.2360 Coma scale, best motor response, obeys commands, unspecified time
R40.2361 Coma scale, best motor response, obeys commands, in the field [EMT or ambulance]
R40.2362 Coma scale, best motor response, obeys commands, at arrival to emergency department
R40.2363 Coma scale, best motor response, obeys commands, at hospital admission
R40.2364 Coma scale, best motor response, obeys commands, 24 hours or more after hospital admission

What has happened to this code

Every change the publisher made, from 2014 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.

FY2014 Added to the draft code set draft Coma scale, best motor response, obeys commands
