P25.1 — Pneumothorax originating in the perinatal period
P25.1 is a billable, specific ICD-10-CM code for pneumothorax originating in the perinatal period. It is valid for submission on a claim.
Other codes that can never be billed with P25.1
These codes carry an Excludes1 note pointing at P25.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading P25.1 alone.
- J93Pneumothorax and air leak
Risk adjustment
P25.1 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 P25.1 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 P25.1.
- Pneumothorax NOS›congenital
- Pneumothorax NOS›perinatal period
- Pneumothorax NOS›spontaneous NOS›newborn
