S54 — Injury of nerves at forearm level
S54 is a non-billable header ICD-10-CM code for injury of nerves at forearm 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 S54
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Excludes2 — not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.
- injury of nerves at wrist and hand level (S64.-)
Code also
Both codes may be needed to describe the encounter fully. Sequencing depends on the reason for the visit.
- any associated open wound (S51.-)
Other codes that can never be billed with S54
These codes carry an Excludes1 note pointing at S54. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S54 alone.
Risk adjustment
S54 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 S54
6 child codes. Green means billable.
