P54.0 — Neonatal hematemesis
P54.0 is a billable, specific ICD-10-CM code for neonatal hematemesis. It is valid for submission on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- neonatal hematemesis due to swallowed maternal blood (P78.2)
Other codes that can never be billed with P54.0
These codes carry an Excludes1 note pointing at P54.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading P54.0 alone.
Risk adjustment
P54.0 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
How P54.0 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to P54.0.
- Hematemesis›newborn, neonatal

Codes that share P54. If P54.0 is not quite right, the correct code is usually one of these.
