Other perinatal hematological disorders (P61) ICD-10-CM
The P61 code range covers other perinatal hematological disorders with 10 ICD-10-CM diagnosis codes. 9 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- transient hypogammaglobulinemia of infancy D80.7

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the P61 range.
Agranulocytosis
A decrease in the number of GRANULOCYTES; (BASOPHILS; EOSINOPHILS; and NEUTROPHILS).
Chemotherapy-Induced Febrile Neutropenia
FEVER accompanied by a significant reduction in NEUTROPHIL count associated with CHEMOTHERAPY.
Febrile Neutropenia
Fever accompanied by a significant reduction in the number of NEUTROPHILS.
Feline Panleukopenia
A highly contagious DNA virus infection of the cat family, characterized by fever, enteritis and bone marrow changes. It is also called feline ataxia, feline agranulocytosis, feline infectious enteritis, cat fever, cat plague, and show fever. It is caused by FELINE PANLEUKOPENIA VIRUS or the closely related MINK ENTERITIS VIRUS or CANINE PARVOVIRUS.
Leukemoid Reaction
A peripheral blood picture resembling that of leukemia or indistinguishable from it on the basis of morphologic appearance alone. (Dorland, 27th ed)
Leukopenia
A decrease in the number of LEUKOCYTES in a blood sample below the normal range (LEUKOCYTE COUNT less than 4000).
Neutropenia
A decrease in the number of NEUTROPHILS found in the blood.
Neutrophils
Granular leukocytes having a nucleus with three to five lobes connected by slender threads of chromatin, and cytoplasm containing fine inconspicuous granules and stainable by neutral dyes.
About the P61 Code Range
ICD-10 code section P61 is used to classify various blood disorders occurring in newborns around the time of birth. These codes cover specific perinatal hematological disorders such as transient neonatal thrombocytopenia, neonatal polycythemia, and anemia related to prematurity or fetal blood loss.
This ICD-10 code for other perinatal hematological disorders includes conditions like P61.0 for transient neonatal thrombocytopenia, which is also known as neonatal alloimmune thrombocytopenia or primary immune thrombocytopenia, helping coders identify platelet shortages in newborns caused by maternal antibodies or exchange transfusions. P61.1 covers polycythemia neonatorum, sometimes called neonatal polycythemia or plethora, where newborns have an abnormally high red blood cell count often linked to placental insufficiency or twin-to-twin transfusion. Codes such as P61.2 and P61.3 address anemia of prematurity and congenital anemia from fetal blood loss, respectively. The section also includes P61.5 for transient neonatal neutropenia and disorders of blood clotting under P61.6. Other specified or unspecified perinatal blood disorders are coded under P61.8 and P61.9. This grouping aids medical coders and professionals in accurately documenting newborn hematologic conditions.
