P28.0 — Primary atelectasis of newborn
P28.0 is a billable, specific ICD-10-CM code for primary atelectasis of newborn. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Primary failure to expand terminal respiratory units
- Pulmonary hypoplasia associated with short gestation
- Pulmonary immaturity NOS
Other codes that can never be billed with P28.0
These codes carry an Excludes1 note pointing at P28.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading P28.0 alone.
- Q33.6Congenital hypoplasia and dysplasia of lung
Risk adjustment
P28.0 risk-adjusts. Under the CMS-HCC V28 model it maps to this category:
- HCC 213 Cardio-Respiratory Failure and Shock0.370 RAF
Coefficient shown for the Community Non-dual Aged segment. A higher HCC in the same hierarchy will suppress this one, so capturing it does not always add score.
How P28.0 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 P28.0.
