P55.9 is a billable ICD code used to specify a diagnosis of hemolytic disease of newborn, unspecified. A 'billable code' is detailed enough to be used to specify a medical diagnosis.


The ICD code P55 is used to code Hemolytic disease of the newborn

Hemolytic disease of the newborn, also known as hemolytic disease of the fetus and newborn, HDN, HDFN, or erythroblastosis fetalis, is an alloimmune condition that develops in a fetus, when the IgG molecules (one of the five main types of antibodies) produced by the mother pass through the placenta. Among these antibodies are some which attack the red blood cells in the fetus' circulation, which are broken down and destroyed (hemolysis). The fetus can develop reticulocytosis and anemia. This fetal disease ranges from mild to very severe, and fetal death from heart failure (hydrops fetalis) can occur. When the disease is moderate or severe, many erythroblasts (immature red blood cells) are present in the fetal blood, and so these forms of the disease can be called erythroblastosis fetalis (or erythroblastosis foetalis).

Equivalent ICD-9 Code GENERAL EQUIVALENCE MAPPINGS (GEM)

Hemolytic disease of fetus or newborn due to other and unspecified isoimmunization (approximate match)

This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code P55.9 and a single ICD9 code, 773.2 is an approximate match for comparison and conversion purposes.
