S42.12 — Fracture of acromial process
Not billable
Is S42.12 billable?
No — S42.12 is a non-billable header code. S42.12 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 42 billable codes beneath S42.12.

How is S42.12 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to S42.12. They show the wording a clinician may have documented, which often differs from the Tabular description.

- Fracture, traumatic › scapula › acromial process › nondisplaced (abduction) (adduction) (separation)
Excludes1 — never code together — inherited from S42
The conditions below can never be reported together with S42.12 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- traumatic amputation of shoulder and upper arm (S48.-)
Use additional code — inherited from Chapter 19
Report an additional code alongside S42.12 to fully describe the condition. S42.12 is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)
Excludes2 — not included here — inherited from Chapter 19
The conditions below are not part of S42.12, but a patient may have both at the same time. When documentation supports it, S42.12 and the excluded code may both be reported.
Excludes2 — not included here — inherited from S40-S49
The conditions below are not part of S42.12, but a patient may have both at the same time. When documentation supports it, S42.12 and the excluded code may both be reported.

How long has S42.12 existed?
S42.12 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
