Is S31.0 billable?

Excludes1 — never code together — inherited from S31
The conditions below can never be reported together with S31.0 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Use additional code — inherited from Chapter 19
Report an additional code alongside S31.0 to fully describe the condition. S31.0 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 S31.0, but a patient may have both at the same time. When documentation supports it, S31.0 and the excluded code may both be reported.
Excludes2 — not included here — inherited from S30-S39
The conditions below are not part of S31.0, but a patient may have both at the same time. When documentation supports it, S31.0 and the excluded code may both be reported.
