S34

S34 — Injury of lumbar and sacral spinal cord and nerves at abdomen, lower back and pelvis level

Non-billable headerICD-10-CM

S34 is a non-billable header ICD-10-CM code for injury of lumbar and sacral spinal cord and nerves at abdomen, lower back and pelvis level. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.

This code requires a 7th character

The appropriate 7th character is to be added to each code from category S34

A: initial encounter
D: subsequent encounter
S: sequela

Code also

Both codes may be needed to describe the encounter fully. Sequencing depends on the reason for the visit.

any associated:
fracture of vertebra (S22.0-, S32.0-)
open wound of abdomen, lower back and pelvis (S31.-)
transient paralysis (R29.5)

Notes

Additional guidance from the ICD-10-CM tabular list.

Code to highest level of lumbar cord injury
Injuries to the spinal cord (S34.0 and S34.1) refer to the cord level and not bone level injury, and can affect nerve roots at and below the level given.

Other codes that can never be billed with S34

These codes carry an Excludes1 note pointing at S34. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S34 alone.

G83.8Other specified paralytic syndromes

Risk adjustment

S34 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead S34

9 child codes. Green means billable.
