ICD-10 code for Nonexpansion

The ICD-10-CM code for Nonexpansion is P28.0 (Primary atelectasis of newborn).

Within P28 (other respiratory conditions originating in the perinatal period), P28.0 is specifically for primary atelectasis of newborn. Related codes cover other and unspecified atelectasis of newborn (P28.1), 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).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), in MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
