About P03.9

P03.9 is the ICD-10-CM diagnosis code for newborn affected by complication of labor and delivery, unspecified. It belongs to category P03 (newborn affected by other complications of labor and delivery), 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 P03, choose P03.9 (complication of labor and delivery, unspecified) only when documentation doesn't support a more specific option: breech delivery and extraction (P03.0), other malpresentation, malposition and disproportion during labor and delivery (P03.1), forceps delivery (P03.2), delivery by vacuum extractor [ventouse] (P03.3), cesarean delivery (P03.4), precipitate delivery (P03.5), abnormal uterine contractions (P03.6) and other specified complications of labor and delivery (P03.8).

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 795 (Normal Newborn, relative weight 0.2022), 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 763.9 (unspecified complication of labor and delivery affecting fetus or newborn).
