About P29.38
P29.38 is the ICD-10-CM diagnosis code for other persistent fetal circulation. It belongs to category P29 (cardiovascular disorders originating in the perinatal period), block P19-P29 (respiratory and cardiovascular disorders specific to the perinatal period) and chapter 16 (certain conditions originating in the perinatal period). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within P29.3, choose P29.38 (Other persistent fetal circulation) only when documentation doesn't support a more specific option: pulmonary hypertension of newborn (P29.30).
As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.
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.
It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.
It was added in FY2018, effective October 1, 2017.
Before ICD-10, this condition was coded in ICD-9-CM as 747.83 (persistent fetal circulation).
