Excludes1 — never code together — inherited from S21
The conditions below can never be reported together with S21.04 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 (partial) of thorax (S28.1)
Use additional code — inherited from Chapter 19
Report an additional code alongside S21.04 to fully describe the condition. S21.04 is sequenced first.

Excludes2 — not included here — inherited from Chapter 19
The conditions below are not part of S21.04, but a patient may have both at the same time. When documentation supports it, S21.04 and the excluded code may both be reported.
