P50.5 — Newborn affected by intrauterine (fetal) blood loss from cut end of co-twin's cord
P50.5 is a billable, specific ICD-10-CM code for newborn affected by intrauterine (fetal) blood loss from cut end of co-twin's cord. It is valid for submission on a claim.
Other codes that can never be billed with P50.5
These codes carry an Excludes1 note pointing at P50.5. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading P50.5 alone.
- P51Umbilical hemorrhage of newborn
Risk adjustment
P50.5 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 P50.5 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 P50.5.
