About P24.00
P24.00 is the ICD-10-CM diagnosis code for meconium aspiration without respiratory symptoms. It belongs to category P24 (neonatal aspiration), block P19-P29 (respiratory and cardiovascular disorders specific to 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 P24.0, choose P24.00 (without respiratory symptoms) only when documentation doesn't support a more specific option: with respiratory symptoms (P24.01).
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 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.
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 770.11 (meconium aspiration without respiratory symptoms).
