ICD10 code of Ebsteins Anomaly and ICD9 code

The primary medical billing code for Ebstein's Anomaly in the ICD-10-CM system is Q22.5, which classifies it as a congenital malformation of the tricuspid valve. Under the older ICD-9-CM system, this condition was coded as 746.2.

What exactly is Ebstein's Anomaly?

Ebstein's Anomaly is a rare congenital heart defect where the tricuspid valve—the valve between the right atrium and the right ventricle—is malformed and positioned lower than normal within the right ventricle. This displacement causes the valve leaflets to be tethered to the ventricular walls, often leading to tricuspid regurgitation, where blood leaks backward into the atrium. Because the right ventricle is effectively smaller and the atrium is enlarged, the heart struggles to pump blood effectively to the lungs. For the 164 people with Ebstein's Anomaly who have joined the DiseaseMaps community, understanding these structural mechanics is often the first step in navigating their long-term cardiac care.

How is Ebstein's Anomaly classified for medical billing?

Medical coding is essential for ensuring that patients with Ebstein's Anomaly receive appropriate insurance coverage and clinical documentation. The transition from ICD-9 to ICD-10 was a major shift in diagnostic specificity.

• ICD-10-CM Code: Q22.5 (Congenital tricuspid stenosis and insufficiency, specifically identifying Ebstein's Anomaly).


• ICD-9-CM Code: 746.2 (Congenital anomaly of the tricuspid valve).

Is Ebstein's Anomaly a hereditary condition?

While most cases of Ebstein's Anomaly occur sporadically, researchers have identified that it is not strictly Mendelian. In rare instances, there may be a familial predisposition, but the vast majority of patients do not have a direct family history of the condition. Clinical geneticists often look for associated conditions, such as atrial septal defects (ASD) or Wolff-Parkinson-White (WPW) syndrome, which frequently co-occur with Ebstein's Anomaly. Genetic counseling is highly recommended for families who have multiple members affected by congenital heart defects to better understand potential recurrence risks.

What are the clinical implications of an Ebstein's Anomaly diagnosis?

The severity of Ebstein's Anomaly varies significantly from patient to patient, ranging from mild anatomical changes that may go undiagnosed until adulthood to severe forms requiring surgical intervention shortly after birth. Patients often require lifelong monitoring by a congenital cardiologist. Common clinical management strategies include:

1. Regular echocardiograms to monitor the degree of tricuspid regurgitation and right ventricular function.


2. Management of arrhythmias, which are common due to the structural changes in the heart.


3. Surgical repair or replacement of the tricuspid valve if symptoms such as cyanosis, heart failure, or severe fatigue emerge.

Next steps

• Consult a board-certified pediatric or adult congenital cardiologist to establish a baseline care plan.


• Request a copy of your medical records containing your specific diagnostic coding (Q22.5) to share with new specialists.


• Join the DiseaseMaps.org community to connect with other patients and caregivers who understand the daily challenges of Ebstein's Anomaly.


• Discuss the necessity of genetic counseling if you are planning to start a family.
