- R40.2341 Coma scale, best motor response, flexion withdrawal, in the field [EMT or ambulance]
- R40.2342 Coma scale, best motor response, flexion withdrawal, at arrival to emergency department
- R40.2343 Coma scale, best motor response, flexion withdrawal, at hospital admission
- R40.2344 Coma scale, best motor response, flexion withdrawal, 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, flexion withdrawal
