P28.1Other and unspecified atelectasis of newborn

P28.1 is the ICD-10-CM diagnosis code for other and unspecified atelectasis of newborn. It belongs to category P28 (other respiratory conditions originating in the perinatal period), block P19-P29 (respiratory and cardiovascular disorders specific to the perinatal period) and chapter 16 (certain conditions originating in the perinatal period). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within P28, choose P28.1 (Other and unspecified atelectasis of newborn) only when documentation doesn't support a more specific option: primary atelectasis of newborn (P28.0), Cyanotic attacks of newborn (P28.2), primary sleep apnea of newborn (P28.3), other apnea of newborn (P28.4), respiratory failure of newborn (P28.5), other specified respiratory conditions of newborn (P28.8) and respiratory condition of newborn, unspecified (P28.9).

To report this condition, pick the subcode that matches the documentation: P28.10 (newborn), P28.11 (syndrome) and P28.19 (newborn).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
