About coding transient neonatal thrombocytopenia
The ICD-10-CM code for transient neonatal thrombocytopenia is P61.0 (Transient neonatal thrombocytopenia).
Within P61 (other perinatal hematological disorders), P61.0 is specifically for transient neonatal thrombocytopenia. Related codes cover polycythemia neonatorum (P61.1), anemia of prematurity (P61.2), congenital anemia from fetal blood loss (P61.3), other congenital anemias, not elsewhere classified (P61.4), transient neonatal neutropenia (P61.5), other transient neonatal disorders of coagulation (P61.6), other specified perinatal hematological disorders (P61.8) and perinatal hematological disorder, unspecified (P61.9).
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.
