Excludes2 — not included here

The conditions below are not part of D04.0, but a patient may have both at the same time. When documentation supports it, D04.0 and the excluded code may both be reported.

carcinoma in situ of vermilion border of lip (D00.01)

Excludes1 — never code together — inherited from D04

The conditions below can never be reported together with D04.0 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

erythroplasia of Queyrat (penis) NOS (D07.4)
melanoma in situ (D03.-)

How long has D04.0 existed?

D04.0 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
