In simple words: This code indicates a birth defect affecting the tricuspid valve of the heart, which controls blood flow between the right atrium and right ventricle. The specific type of defect is not specified by this code.

This code represents a congenital malformation of the tricuspid valve that is not further specified or classified elsewhere in the ICD-10-CM.

Example 1: A newborn infant is diagnosed with a heart murmur. Upon echocardiography, a malformation of the tricuspid valve is discovered, but the exact nature of the malformation is not clearly defined. The physician uses Q22.9 to document the condition., A pediatric cardiologist reviews the medical records of a child with a history of congenital heart disease. Previous imaging studies indicate a problem with the tricuspid valve, but the specific defect was not diagnosed. In the absence of more specific information, the cardiologist assigns Q22.9., A fetal ultrasound reveals a possible abnormality of the tricuspid valve. Until a more definitive diagnosis can be made after birth, Q22.9 is used to document the suspected congenital malformation.

Documentation should include details of the clinical findings, imaging studies (such as echocardiogram), and any other relevant diagnostic tests that support the diagnosis of a congenital tricuspid valve malformation. If the specific type of malformation is later determined, the code should be updated accordingly.

** For outpatient reporting, append a diagnostic confidence indicator (A, G, V, or Z).
