Excludes1 — never code together
The conditions below can never be reported together with S01 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- open skull fracture (S02.- with 7th character B)
Excludes2 — not included here
The conditions below are not part of S01, but a patient may have both at the same time. When documentation supports it, S01 and the excluded code may both be reported.
Code also
Two codes may be needed to describe the condition fully. Whether S01 is sequenced first depends on the reason for the encounter.
Use additional code — inherited from Chapter 19
Report an additional code alongside S01 to fully describe the condition. S01 is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)
Excludes2 — not included here — inherited from Chapter 19

How long has S01 existed?
S01 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
