S42.016G — Posterior displaced fracture of sternal end of unspecified clavicle, subsequent encounter for fracture with delayed healing
Is S42.016G billable?
Yes, but S42.016G is an unspecified code. S42.016G is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, S42.016G is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting S42.016G — the more specific alternatives are listed below.

What does the 7th character "G" mean in S42.016G?
In S42.016G, the 7th character G means subsequent encounter for fracture with delayed healing. The 7th character is required for S42.016G to be a valid, complete code.

- Fracture, traumatic › clavicle › sternal end › posterior (abduction) (adduction) (separation)
Excludes1 — never code together — inherited from S42
The conditions below can never be reported together with S42.016G 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 S42.016G to fully describe the condition. S42.016G 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 S42.016G, but a patient may have both at the same time. When documentation supports it, S42.016G and the excluded code may both be reported.
Excludes2 — not included here — inherited from S40-S49
The conditions below are not part of S42.016G, but a patient may have both at the same time. When documentation supports it, S42.016G and the excluded code may both be reported.
Excludes2 — not included here — inherited from S42
The conditions below are not part of S42.016G, but a patient may have both at the same time. When documentation supports it, S42.016G and the excluded code may both be reported.
- periprosthetic fracture around internal prosthetic shoulder joint (M97.3)
How long has S42.016G existed?
S42.016G 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.
