Spontaneous abortion (O03)
ICD-10 codes O03 classify cases of spontaneous abortion, commonly known as miscarriage, including both incomplete and complete losses of pregnancy without external intervention. These codes cover a spectrum of clinical scenarios from uncomplicated miscarriages to various complications that can follow.
This section includes codes for incomplete spontaneous abortion (O03.0–O03.4), which involves retained fetal tissue and possible infections or hemorrhage, and complete or unspecified spontaneous abortion (O03.5–O03.9), covering full expulsion of pregnancy products with or without complications. Synonyms such as "incomplete miscarriage," "inevitable miscarriage," and "complete miscarriage" help link common clinical terms to these codes. Notably, the codes address complications like pelvic infections, delayed hemorrhage, embolism, shock, renal failure, metabolic disorders, pelvic organ damage, sepsis, urinary tract infections, cardiac arrest, and other venous complications that may arise after a miscarriage. This classification aids medical coders and healthcare providers in accurately documenting and billing for miscarriage cases and their diverse outcomes, making the ICD-10 code for spontaneous abortion essential for proper clinical management and reporting.

Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Afibrinogenemia
A deficiency or absence of FIBRINOGEN in the blood.
Broad Ligament
A broad fold of peritoneum that extends from the side of the uterus to the wall of the pelvis.
Fibrinogen
Plasma glycoprotein clotted by thrombin, composed of a dimer of three non-identical pairs of polypeptide chains (alpha, beta, gamma) held together by disulfide bonds. Fibrinogen clotting is a sol-gel change involving complex molecular arrangements: whereas fibrinogen is cleaved by thrombin to form polypeptides A and B, the proteolytic action of other enzymes yields different fibrinogen degradation products.
Oliguria
Decreased URINE output that is below the normal range. Oliguria can be defined as urine output of less than or equal to 0.5 or 1 ml/kg/hr depending on the age.
Parametritis
Inflammation of the parametrium, the connective tissue of the pelvic floor, extending from the subserous coat of the uterus laterally between the layers of the BROAD LIGAMENT.
Urine
Liquid by-product of excretion produced in the kidneys, temporarily stored in the bladder until discharge through the URETHRA.
