About coding meconium aspiration
The ICD-10-CM code for meconium aspiration is P24.00 (Meconium aspiration without respiratory symptoms). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on P24.00.
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.
