Clinical InformationClinical

  • Afibrinogenemia

    a deficiency or absence of fibrinogen in the blood.

  • Postpartum Hemorrhage

    excess blood loss from uterine bleeding associated with obstetric labor or childbirth. it is defined as blood loss greater than 500 ml or of the amount that adversely affects the maternal physiology, such as blood pressure and hematocrit. postpartum hemorrhage is divided into two categories, immediate (within first 24 hours after birth) or delayed (after 24 hours postpartum).

  • 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.

  • Afibrinogenemia

    a blood coagulation disorder characterized by the complete absence of fibrinogen in the blood, resulting in bleeding.

  • Early Postpartum Hemorrhage|Primary Postpartum Hemorrhage|Primary Postpartum Hemorrhage

    cumulative blood loss of greater than or equal to 1000 ml or blood loss accompanied by signs or symptoms of hypovolemia within 24 hours following the birth process (includes intrapartum loss). (revitalize)

  • GAIA Level 1 Postpartum Hemorrhage|Global Alignment of Immunization safety Assessment in pregnancy Level 1 Postpartum Hemorrhage|Level 1 Postpartum Haemorrhage

    gaia level 1 postpartum hemorrhage is the presence of genital bleeding after delivery, leading to severe maternal outcome (maternal death or maternal near miss) as defined by who.

  • GAIA Level 2 Postpartum Hemorrhage|Global Alignment of Immunization safety Assessment in pregnancy Level 2 Postpartum Hemorrhage|Level 2 Postpartum Haemorrhage

    gaia level 2 postpartum hemorrhage is defined by the presence of the following criteria: genital bleeding after delivery with at least one of the following: a) measured abnormal bleeding (1000ml or more); or b) any bleeding leading to hypotension or blood transfusion.

  • GAIA Level 3 Postpartum Hemorrhage|Global Alignment of Immunization safety Assessment in pregnancy Level 3 Postpartum Hemorrhage|Level 3 Postpartum Haemorrhage

    gaia level 3 postpartum hemorrhage is defined by the presence of genital bleeding after delivery that is estimated at 1000ml or more.

  • GAIA Postpartum Hemorrhage Level of Diagnostic Certainty Terminology|Global Alignment of Immunization safety Assessment in pregnancy Postpartum Hemorrhage Level of Diagnostic Certainty Terminology

    a subset of terminology related to postpartum hemorrhage, developed by the global alignment of immunization safety assessment in pregnancy consortium to aid in monitoring and improving fetal and maternal outcomes.

  • GAIA Postpartum Hemorrhage Level of Diagnostic Certainty|Global Alignment of Immunization safety Assessment in pregnancy Postpartum Hemorrhage Level of Diagnostic Certainty|Postpartum Hemorrhage Level of Diagnostic Certainty

    a classification of maternal and fetal outcomes relating to postpartum hemorrhage, developed by the global alignment of immunization safety assessment in pregnancy, based on the extent to which the diagnosis has been confirmed.

  • Late Postpartum Hemorrhage|Delayed Postpartum Hemorrhage|Delayed Postpartum Hemorrhage|Secondary Postpartum Hemorrhage|Secondary Postpartum Hemorrhage

    excessive blood loss between 24 hours after delivery through four weeks that requires intervention.

  • Postpartum Hemorrhage

    hemorrhage defined as a blood loss in excess of 500 ml after vaginal delivery or more than 1000 ml after a cesarean delivery.

Patient EducationClinical

Bleeding Disorders

Normally, if you get hurt, your body forms a blood clot to stop the bleeding. For blood to clot, your body needs cells called platelets and proteins known as clotting factors. If you have a bleeding disorder, you either do not have enough platelets or clotting factors or they don't work the way they should.

Questions About O72.3Overview

Is O72.3 (Postpartum hemorrhage) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report postpartum coagulation defects on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

Who can O72.3 be reported for?

The Medicare Code Editor checks postpartum coagulation defects against patient demographics: this code is intended for maternity cases (age 9 through 64). Claims outside these limits are flagged as inconsistent.

What is the ICD-9 equivalent of O72.3?

Under the General Equivalence Mappings, postpartum coagulation defects converts to ICD-9-CM 666.32 (p/p coag def-del w p/p) and 666.34 (postpart coag def-postpa). The mapping is approximate, so confirm the match fits the documentation.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
