About coding neonatal screening abnormal
The ICD-10-CM code for neonatal screening abnormal is P09.9 (Abnormal findings on neonatal screening, unspecified). The official index lists 12 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on P09.9.
Within P09, choose P09.9 (unspecified) only when documentation doesn't support a more specific option: for inborn errors of metabolism (P09.1), for congenital endocrine disease (P09.2), for congenital hematologic disorders (P09.3), for cystic fibrosis (P09.4), for critical congenital heart disease (P09.5), abnormal findings on neonatal hearing screening (P09.6) and other abnormal findings on neonatal screening (P09.8).
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 947 (Signs and Symptoms with MCC, relative weight 1.261) and DRG 948 (Signs and Symptoms without MCC, relative weight 0.7835), in 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.
