Clinical Terms in This Code Range

Definitions from the National Library of Medicine for conditions coded in the O90 range.

Hepatorenal Syndrome

Functional KIDNEY FAILURE in patients with liver disease, usually LIVER CIRRHOSIS or portal hypertension (HYPERTENSION, PORTAL), and in the absence of intrinsic renal disease or kidney abnormality. It is characterized by intense renal vasculature constriction, reduced renal blood flow, OLIGURIA, and sodium retention.

Maternal Death

The death of the female parent.

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.

Vesicovaginal Fistula

An abnormal anatomical passage between the URINARY BLADDER and the VAGINA.

About the O90 Code Range

The ICD-10 code section O90 covers a range of complications that can occur during the puerperium, the period following childbirth. These codes are used to categorize specific issues such as cesarean wound problems, postpartum mood disturbances, and acute kidney failure, among others unique to the postnatal phase.

This set includes codes for complications like O90.0 (disruption of cesarean delivery wound), often referred to as cesarean wound dehiscence; and O90.1, which addresses the disruption of perineal obstetric wounds, including episiotomy or laceration disruptions. For heart-related issues postpartum, O90.3 is applied to peripartum cardiomyopathy, also known as postpartum cardiomyopathy. Kidney failure following delivery is captured under O90.4 and more specifically hepatorenal syndrome under O90.41. The code O90.6 is used for postpartum mood disorders, sometimes called maternity blues or postpartum depression. These detailed codes help healthcare professionals and coders accurately report and track complications such as postpartum thyroiditis, hematomas of obstetric wounds, and various less common or unspecified puerperal complications. This specificity aids in clinical care and health record documentation by directly linking conditions like "cesarean wound disruption" or "postpartum mood disturbance" to their precise ICD-10 codes.
