Specific code 2014 ICD-9-CM Diagnosis Code 773.2
Hemolytic disease of fetus or newborn due to other and unspecified isoimmunization
  • Billable Code
  • Newborn/Neonate Only Dx (0 years)
  • Short description: NB hemolyt dis-isoim NEC.
  • ICD-9-CM 773.2 will be replaced by an equivalent ICD-10-CM code (or codes) when the United States transitions from ICD-9-CM to ICD-10-CM on October 1, 2015.
  • ICD-9-CM 773.2 is a billable medical code that can be used to specify a diagnosis on a reimbursement claim.
Disease Synonyms
  • Hydrops fetalis due to isoimmunization
Clinical Information
  • A condition characterized by the abnormal presence of erythroblasts in the circulation of the fetus or newborns. It is a disorder due to blood group incompatibility, such as the maternal alloimmunization by fetal antigen rh factors leading to hemolysis of erythrocytes, hemolytic anemia (anemia, hemolytic), general edema (hydrops fetalis), and severe jaundice in newborn.
  • Hemolytic anemia of the fetus or newborn caused by transplacental transmission of maternally formed antibody, usually secondary to an incompatibility between the blood groups of mother and offspring.
Applies To
  • Erythroblastosis (fetalis) (neonatorum) NOS
  • Hemolytic disease (fetus) (newborn) NOS
  • Jaundice or anemia due to other and unspecified blood-group incompatibility
ICD-9-CM Coding Information
  • 773.2 is only applicable to newborns of age 0 years.
Convert to ICD-10-CM: 773.2 converts approximately to:
  • 2014 ICD-10-CM P55.8 Other hemolytic diseases of newborn
    Or:
  • 2014 ICD-10-CM P55.9 Hemolytic disease of newborn, unspecified

ICD-9-CM codes are used in medical billing and coding to describe diseases, injuries, symptoms and conditions. ICD-9-CM 773.2 is one of thousands of ICD-9-CM codes used in healthcare. Although ICD-9-CM and CPT codes are largely numeric, they differ in that CPT codes describe medical procedures and services. Can't find a code?
