P22.1 — Transient tachypnea of newborn
P22.1 is a billable, specific ICD-10-CM code for transient tachypnea 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.
- Idiopathic tachypnea of newborn
- Respiratory distress syndrome, type II
- Wet lung syndrome
Other codes that can never be billed with P22.1
These codes carry an Excludes1 note pointing at P22.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading P22.1 alone.
Risk adjustment
P22.1 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 P22.1 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 P22.1.
