S52.009E — Unspecified fracture of upper end of unspecified ulna, subsequent encounter for open fracture type I or II with routine healing
Is S52.009E billable?
Yes, but S52.009E is an unspecified code. S52.009E is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, S52.009E 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 S52.009E — the more specific alternatives are listed below.

Excludes1 — never code together — inherited from S52
The conditions below can never be reported together with S52.009E 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 forearm (S58.-)
Use additional code — inherited from Chapter 19
Report an additional code alongside S52.009E to fully describe the condition. S52.009E 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 S52.009E, but a patient may have both at the same time. When documentation supports it, S52.009E and the excluded code may both be reported.
Excludes2 — not included here — inherited from S50-S59
The conditions below are not part of S52.009E, but a patient may have both at the same time. When documentation supports it, S52.009E and the excluded code may both be reported.
Excludes2 — not included here — inherited from S52
The conditions below are not part of S52.009E, but a patient may have both at the same time. When documentation supports it, S52.009E and the excluded code may both be reported.
Excludes2 — not included here — inherited from S52.0
The conditions below are not part of S52.009E, but a patient may have both at the same time. When documentation supports it, S52.009E and the excluded code may both be reported.
How long has S52.009E existed?
S52.009E 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.
