Arterial embolism and thrombosis (I74)

Browse all the diagnosis codes used for arterial embolism and thrombosis (i74). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range. This format makes it simple to browse diagnosis codes in this chapter or section and find what you're looking for. We've also added green checkmark icons to label billable codes, and red warning icons for non-billable ones. This makes it easy to identify which codes can be billed.

Clinical Information

Embolic Protection Devices - Vascular filters or occlusive devices that provide mechanical protection of the distal end organ from blood clots or EMBOLISM-causing debri dislodged during ENDOVASCULAR PROCEDURES.

Embolism - Blocking of a blood vessel by an embolus which can be a blood clot or other undissolved material in the blood stream.

Embolism and Thrombosis - A collective term for pathological conditions which are caused by the formation of a blood clot (THROMBUS) in a blood vessel, or by blocking of a blood vessel with an EMBOLUS, undissolved materials in the blood stream.

Embolism, Air - Blocking of a blood vessel by air bubbles that enter the circulatory system, usually after TRAUMA; surgical procedures, or changes in atmospheric pressure.

Embolism, Amniotic Fluid - Blocking of maternal circulation by AMNIOTIC FLUID that is forced into uterine VEINS by strong UTERINE CONTRACTION near the end of pregnancy. It is characterized by the sudden onset of severe respiratory distress and HYPOTENSION that can lead to maternal DEATH.

Embolism, Cholesterol - Blocking of a blood vessel by CHOLESTEROL-rich atheromatous deposits, generally occurring in the flow from a large artery to small arterial branches. It is also called arterial-arterial embolization or atheroembolism which may be spontaneous or iatrogenic. Patients with spontaneous atheroembolism often have painful, cyanotic digits of acute onset.

Embolism, Fat - Blocking of a blood vessel by fat deposits in the circulation. It is often seen after fractures of large bones or after administration of CORTICOSTEROIDS.

Embolism, Paradoxical - Blockage of an artery due to passage of a clot (THROMBUS) from a systemic vein to a systemic artery without its passing through the lung which acts as a filter to remove blood clots from entering the arterial circulation. Paradoxical embolism occurs when there is a defect that allows a clot to cross directly from the right to the left side of the heart as in the cases of ATRIAL SEPTAL DEFECTS or open FORAMEN OVALE. Once in the arterial circulation, a clot can travel to the brain, block an artery, and cause a STROKE.

Intracranial Embolism - Blocking of a blood vessel in the SKULL by an EMBOLUS which can be a blood clot (THROMBUS) or other undissolved material in the blood stream. Most emboli are of cardiac origin and are associated with HEART DISEASES. Other non-cardiac sources of emboli are usually associated with VASCULAR DISEASES.

Intracranial Embolism and Thrombosis - Embolism or thrombosis involving blood vessels which supply intracranial structures. Emboli may originate from extracranial or intracranial sources. Thrombosis may occur in arterial or venous structures.

Ischemic Stroke - Stroke due to BRAIN ISCHEMIA resulting in interruption or reduction of blood flow to a part of the brain. When obstruction is due to a BLOOD CLOT formed within in a cerebral blood vessel it is a thrombotic stroke. When obstruction is formed elsewhere and moved to block a cerebral blood vessel (see CEREBRAL EMBOLISM) it is referred to as embolic stroke. Wake-up stroke refers to ischemic stroke occurring during sleep while cryptogenic stroke refers to ischemic stroke of unknown origin.

Neoplastic Cells, Circulating - Exfoliate neoplastic cells circulating in the blood and associated with metastasizing tumors.

Pulmonary Embolism - Blocking of the PULMONARY ARTERY or one of its branches by an EMBOLUS.

Instructional Notations

Includes

This note appears immediately under a three character code title to further define, or give examples of, the content of the category.

• embolic infarction
• embolic occlusion
• thrombotic infarction
• thrombotic occlusion

Code First

Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.

• embolism and thrombosis complicating abortion or ectopic or molar pregnancy O00 O07 O08.2
• embolism and thrombosis complicating pregnancy, childbirth and the puerperium O88

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.
