Complications following (induced) termination of pregnancy (O04) ICD-10-CM
The O04 code range covers complications following (induced) termination of pregnancy with 15 ICD-10-CM diagnosis codes. 13 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- complications following (induced) termination of pregnancy
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the O04 range.
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.
Vesicovaginal Fistula
An abnormal anatomical passage between the URINARY BLADDER and the VAGINA.
About the O04 Code Range
The ICD-10 code O04 and its subcodes identify complications occurring after an induced termination of pregnancy. These codes help medical professionals document and classify a wide range of specific health issues resulting from such procedures.
The section covers conditions including genital tract and pelvic infections (O04.5) such as parametritis or endometritis, and hemorrhage complications (O04.6) like secondary hemorrhage or afibrinogenemia following the procedure. Other critical codes address embolism (O04.7), including amniotic fluid and air embolism. Also included are complications like shock (O04.81), renal failure (O04.82), and metabolic disorders (O04.83). Damage to pelvic organs and tissues (O04.84) covers injuries such as lacerations or perforations affecting the uterus, bladder, or vagina. Additional codes specify venous complications (O04.85), cardiac arrest (O04.86), sepsis (O04.87), urinary tract infection (O04.88), and other complications like hepatic necrosis or retained products of conception (O04.89). Including synonyms like "parametritis" or "induced termination complicated by septic shock" helps link clinical terms to the respective ICD-10 codes, supporting accurate coding of induced abortion-related complications.
