About coding fetal stress
The ICD-10-CM code for fetal stress is P84 (Other problems with newborn). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on P84.
Don't report P84 together with the conditions in its Excludes1 note: intracranial hemorrhage due to anoxia or hypoxia (P52.-), hypoxic ischemic encephalopathy [HIE] (P91.6-) and late metabolic acidosis of newborn (P74.0).
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 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.
