- traumatic amputation (partial) of thorax (S28.1)
Use additional code — inherited from Chapter 19
Report an additional code alongside S21.129 to fully describe the condition. S21.129 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 S21.129, but a patient may have both at the same time. When documentation supports it, S21.129 and the excluded code may both be reported.
