About ICD-10-CM S41

ICD-10-CM code S41 represents Open wound of shoulder and upper arm. This is a non-billable header code in the Injury, Poisoning, and External Causes chapter (block S41). The 2026 edition of ICD-10-CM S41 became effective on October 1, 2025. Non-billable codes cannot be used as a primary or secondary diagnosis on a claim, use a more specific child code instead.

Coding Tips for S41

Specialist guidance from the PayerReady Medical Coding Team. Specificity warnings, HCC capture rules, sequencing notes.

Injury chapter (S00-T88): 7th character extension required

Injury codes require a 7th character: A (initial encounter, active treatment), D (subsequent, healing/recovery), S (sequela, late effect of original injury). Codes with fewer than 6 characters need the placeholder X to bring them to 6 characters before adding the 7th. Wrong or missing 7th character is the #1 cause of injury claim denials.

Type 1 Excludes

Pure excludes, these codes can never be coded together with S41. The conditions are mutually exclusive (e.g., congenital vs acquired forms).

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

Type 2 Excludes

Not included here, the excluded code is not part of S41, but a patient may have both conditions at the same time. Both codes may be coded together when applicable.

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

Coding Notes

Code Also

  • any associated wound infection

Seven Chr Note

  • The appropriate 7th character is to be added to each code from category S41
