779.9
ICD-9-CMThis code represents a health condition or abnormality present in a newborn that originated during the perinatal period (from 28 weeks gestation through 28 days after birth), but for which a more specific diagnosis cannot be determined. It indicates a problem with a perinatal origin without identifying the exact nature of that problem.
This code is used when documentation clearly indicates a perinatal condition affecting the neonate, but the specific type of condition is not yet diagnosed or is documented as "unspecified." It's appropriate for initial encounters or when diagnostic workup is incomplete and a more precise code from categories 760-779 is unavailable.
