P92.4Overfeeding of newborn

P92.4 is the ICD-10-CM diagnosis code for Overfeeding of newborn. It belongs to category P92 (feeding problems of newborn), block P90-P96 (other disorders originating in the perinatal period) 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 P92 (feeding problems of newborn), P92.4 is specifically for Overfeeding of newborn. Related codes cover vomiting of newborn (P92.0), Regurgitation and rumination of newborn (P92.1), slow feeding of newborn (P92.2), Underfeeding of newborn (P92.3), neonatal difficulty in feeding at breast (P92.5), failure to thrive in newborn (P92.6), other feeding problems of newborn (P92.8) and feeding problem of newborn, unspecified (P92.9).

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 hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 779.31 (feeding problems in newborn).
