About P01.9
P01.9 is the ICD-10-CM diagnosis code for newborn affected by maternal complication of pregnancy, unspecified. It belongs to category P01 (newborn affected by maternal complications of pregnancy), block P00-P04 (newborn affected by maternal factors and by complications of pregnancy, labor, and delivery) and chapter 16 (certain conditions originating in the perinatal period). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within P01, choose P01.9 (maternal complication of pregnancy, unspecified) only when documentation doesn't support a more specific option: incompetent cervix (P01.0), premature rupture of membranes (P01.1), oligohydramnios (P01.2), polyhydramnios (P01.3), ectopic pregnancy (P01.4), multiple pregnancy (P01.5), maternal death (P01.6), malpresentation before labor (P01.7) and 1 more.
Code first: any current condition in newborn.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 794 (Neonate with Other Significant Problems, relative weight 1.4935), 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.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2017 (title revised).
Before ICD-10, this condition was coded in ICD-9-CM as 761.9 (unspecified maternal complication of pregnancy affecting fetus or newborn).
