S27.0XXS is a billable, specific ICD-10-CM code for traumatic pneumothorax, sequela. It is valid for submission on a claim.
7th character "S" — sequela
The appropriate 7th character is to be added to each code from category S27
- A

- D
- subsequent encounter
- S
- sequela
Excludes1 — never code together

Risk adjustment
S27.0XXS does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
