Is S41 a billable ICD-10-CM code?

No. S41 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does S41 sit in the tabular list?

Injury, poisoning and certain other consequences of external causes (S00-T88), in the block Injuries to the shoulder and upper arm (S40-S49).

What cannot be coded together with S41?

S41 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

S41

S41 — Open wound of shoulder and upper arm

Non-billable headerICD-10-CM

S41 is a non-billable header ICD-10-CM code for open wound of shoulder and upper arm. 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 S41

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.

traumatic amputation of shoulder and upper arm (S48.-)

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 fracture of shoulder and upper arm (S42.- with 7th character B or C)

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 S41

These codes carry an Excludes1 note pointing at S41. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S41 alone.

S40.27Other superficial bite of shoulder
S40.87Other superficial bite of upper arm

Risk adjustment

S41 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 S41

2 child codes. Green means billable.
