Congenital Malformations of Aortic and Mitral Valves
Code Q23.8, Other congenital malformations of aortic and mitral valves, has been expanded, and three new codes have been created to identify bicuspid aortic valve (BAV), and congenital mitral valve cleft leaflet. The new codes are as follows: Q23.81, Bicuspid aortic valve Q23.82, Congenital mitral valve cleft leaflet Q23.88, Other congenital malformations of aortic and mitral valves A normal aortic valve has three cusps, or leaflets. Patients with BAV have an aortic valve that only has two cusps, which increases the risk of possible health problems such as, aortic valve stenosis, aortic valve...
