Other congenital malformations of tricuspid valve

This code signifies congenital structural abnormalities of the tricuspid valve that do not fit into more specific categories like tricuspid atresia or Ebstein's anomaly. These malformations can affect the leaflets, annulus, or chordae tendineae, leading to varying degrees of tricuspid regurgitation or stenosis.

Use this code when documentation specifies a congenital tricuspid valve malformation that is not otherwise classified. This includes conditions such as congenital tricuspid valve dysplasia, hypoplasia, or prolapse when congenital. Supporting documentation should clearly state the congenital nature and the specific type of tricuspid valve anomaly.

• Do not use this code for acquired tricuspid valve disorders; those are classified elsewhere.
• Ensure the documentation explicitly states "congenital" to differentiate from acquired conditions.
• If a more specific congenital tricuspid valve anomaly (e.g., Ebstein's anomaly, tricuspid atresia) is documented, use the corresponding specific code instead.
