Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the O90 range.
Peripartum Cardiomyopathy
A rare form of dilated cardiomyopathy which causes heart enlargement and weakness during the last month of pregnancy or within five months of delivery.
Postpartum Thyroiditis
Transient autoimmune thyroiditis occurring in the POSTPARTUM PERIOD. It is characterized by the presence of high titers of AUTOANTIBODIES against THYROID PEROXIDASE and THYROGLOBULIN. Clinical signs include the triphasic thyroid hormone pattern: beginning with THYROTOXICOSIS, followed with HYPOTHYROIDISM, then return to euthyroid state by 1 year postpartum.
About the O90 Code Range
These complications occur after childbirth and include wound problems, a heart muscle condition, acute kidney failure, thyroid inflammation, mood disturbance, and anemia.
The wound codes distinguish reopened cesarean delivery wounds (O90.0) and perineal obstetric wounds (O90.1) from blood collections in obstetric wounds (O90.2). Separate codes identify a heart muscle condition around childbirth (O90.3), thyroid inflammation (O90.5), and mood disturbance (O90.6).
Postpartum acute kidney failure (O90.4) splits into liver-and-kidney syndrome following labor and delivery (O90.41) and other postpartum acute kidney failure (O90.49). Other complications (O90.8) split into anemia (O90.81) and other complications (O90.89). O90.9 identifies an unspecified complication.
