About S14.3
S14.3 is the ICD-10-CM diagnosis code for injury of brachial plexus. It belongs to category S14 (injury of nerves and spinal cord at neck level), block S10-S19 (injuries to the neck) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.
Within S14 (injury of nerves and spinal cord at neck level), S14.3 is specifically for injury of brachial plexus. Related codes cover concussion and edema of cervical spinal cord (S14.0), other and unspecified injuries of cervical spinal cord (S14.1), injury of nerve root of cervical spine (S14.2), injury of peripheral nerves of neck (S14.4), injury of cervical sympathetic nerves (S14.5), injury of other specified nerves of neck (S14.8) and injury of unspecified nerves of neck (S14.9).
Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
