Excludes1 — never code together — inherited from P50-P61
The conditions below can never be reported together with P55.8 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 Chapter 16
The conditions below are not part of P55.8, but a patient may have both at the same time. When documentation supports it, P55.8 and the excluded code may both be reported.
How long has P55.8 existed?
P55.8 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.
