Not billable
Is W18 billable?

Excludes1 — never code together — inherited from W00-W19
The conditions below can never be reported together with W18 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here — inherited from W00-W19
The conditions below are not part of W18, but a patient may have both at the same time. When documentation supports it, W18 and the excluded code may both be reported.

How long has W18 existed?
W18 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
