ICD-10 code for lumbosacral plexus injury

The ICD-10-CM code for lumbosacral plexus injury is S34.4 (Injury of lumbosacral plexus).

Within S34 (injury of lumbar and sacral spinal cord and nerves at abdomen, lower back and pelvis level), S34.4 is specifically for injury of lumbosacral plexus. Related codes cover concussion and edema of lumbar and sacral spinal cord (S34.0), other and unspecified injury of lumbar and sacral spinal cord (S34.1), injury of nerve root of lumbar and sacral spine (S34.2), injury of cauda equina (S34.3), injury of lumbar, sacral and pelvic sympathetic nerves (S34.5), injury of peripheral nerve(s) at abdomen, lower back and pelvis level (S34.6), injury of other nerves at abdomen, lower back and pelvis level (S34.8) and injury of unspecified nerves at abdomen, lower back and pelvis level (S34.9).

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.
