About P74.41

P74.41 is the ICD-10-CM diagnosis code for Alkalosis of newborn. It belongs to category P74 (other transitory neonatal electrolyte and metabolic disturbances), block P70-P74 (transitory endocrine and metabolic disorders specific to newborn) 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 P74.4 (other transitory electrolyte disturbances of newborn), P74.41 is specifically for Alkalosis of newborn. Related codes cover disturbances of chlorine balance of newborn (P74.42) and other transitory electrolyte disturbance of newborn (P74.49).

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 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 was added in FY2019, effective October 1, 2018.
