In simple words: This code refers to other blood-related problems that occur in newborns (up to 28 days old) that aren't covered by other, more specific codes.

This code represents other hematological disorders originating in the perinatal period not classified elsewhere.

Example 1: A newborn presents with prolonged bleeding from the umbilical cord. After ruling out other coagulation disorders, the physician diagnoses a rare, unspecified platelet dysfunction and uses P61 to document the condition., An infant demonstrates unusual bruising and petechiae. Investigations reveal an unclassified form of neonatal thrombocytopenia, where the cause is not alloimmune or autoimmune. P61 is used for coding., A neonate displays signs of a hematological disorder not fitting into established categories, such as unusual red blood cell morphology or abnormal blood clotting times. In the absence of a more specific diagnosis, P61 can be applied.

Thorough documentation is essential when utilizing P61.This should include: complete blood counts with differentials, coagulation studies (PT, PTT, INR), blood smear analysis, any relevant imaging (e.g., ultrasound for organomegaly), and details of the clinical presentation (e.g., bruising, bleeding, pallor). Additional specialized tests may be required depending on the suspected underlying condition.

** Excludes1: transient hypogammaglobulinemia of infancy (D80.7)
