S51 — Open wound of elbow and forearm
S51 is a non-billable header ICD-10-CM code for open wound of elbow and forearm. 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 S51
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
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.
- open wound of wrist and hand (S61.-)
Code also
Both codes may be needed to describe the encounter fully. Sequencing depends on the reason for the visit.
- any associated wound infection
Other codes that can never be billed with S51
These codes carry an Excludes1 note pointing at S51. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S51 alone.
Risk adjustment
S51 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 S51
2 child codes. Green means billable.
