Excludes2 — not included here — inherited from Chapter 19
The conditions below are not part of S27.3, but a patient may have both at the same time. When documentation supports it, S27.3 and the excluded code may both be reported.
Excludes2 — not included here — inherited from S20-S29
The conditions below are not part of S27.3, but a patient may have both at the same time. When documentation supports it, S27.3 and the excluded code may both be reported.
- burns and corrosions (T20-T32)
