About the O03 Code Range
A spontaneous abortion, also called a miscarriage, means pregnancy tissue leaves the body before full term without deliberate interference.
O03 first separates incomplete miscarriages from complete or unspecified miscarriages. Within each group, the subdivisions distinguish infections, delayed or excessive bleeding, other complications, and no complication. The other-complication branches, O03.3 and O03.8, split further by the complication named, such as kidney failure, pelvic organ damage, or urinary tract infection. O03.4 and O03.9 identify miscarriages without complication.
