Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the O44 range.
Low-Lying Placenta
A condition in which the placental edge is within 2 cm of but not covering the cervical os.
Placenta Previa
Abnormal placentation in which the PLACENTA implants in the lower segment of the UTERUS (the zone of dilation) and may cover part or all of the opening of the CERVIX. It is often associated with serious antepartum bleeding and PREMATURE LABOR.
About the O44 Code Range
Placenta previa means the placenta attaches low in the uterus and may cover part or all of the cervical opening.
The subdivisions distinguish complete placenta previa, partial placenta previa, and a low-lying placenta. Each has a subdivision without hemorrhage or not otherwise specified and one with hemorrhage: O44.0 and O44.1 for complete, O44.2 and O44.3 for partial, and O44.4 and O44.5 for low-lying placenta. Each group then separates first, second, third, and unspecified trimester.
