P09Abnormal findings on neonatal screening

P09 is the ICD-10-CM diagnosis code for abnormal findings on neonatal screening. It belongs to block P09 (abnormal findings on neonatal screening) and chapter 16 (certain conditions originating in the perinatal period). It is a header code, so it can't be reported by itself; one of its 8 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: P09.1 (for inborn errors of metabolism), P09.2 (for congenital endocrine disease), P09.3 (for congenital hematologic disorders), P09.4 (for cystic fibrosis), P09.5 (for critical congenital heart disease), P09.6 (screening), P09.8 (screening) and P09.9 (unspecified).

The conditions in its Excludes2 note aren't part of P09, but may be coded alongside it if the patient has both: nonspecific serologic evidence of human immunodeficiency virus [HIV] (R75).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2022 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 796.6 (abnormal findings on neonatal screening).
