About coding weight check newborn
The ICD-10-CM code for weight check newborn is Z00.111 (Health examination for newborn 8 to 28 days old).
Within Z00.11 (newborn health examination), Z00.111 is specifically for health examination for newborn 8 to 28 days old. Related codes cover under 8 days old (Z00.110).
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) and DRG 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period) and MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
