How is S52.21 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to S52.21. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Fracture, traumatic › ulna › shaft › greenstick (abduction) (adduction) (separation)
Excludes1 — never code together — inherited from S52
The conditions below can never be reported together with S52.21 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 S52.21 to fully describe the condition. S52.21 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 S52.21, but a patient may have both at the same time. When documentation supports it, S52.21 and the excluded code may both be reported.
Excludes2 — not included here — inherited from S50-S59
The conditions below are not part of S52.21, but a patient may have both at the same time. When documentation supports it, S52.21 and the excluded code may both be reported.
