What This Code Means

A birth defect affecting the aortic and mitral valves of the heart where the specific type of malformation is not identified.

  • •Use this code only when the specific valve defect cannot be determined; if the defect is identified, use more specific Q23 codes (Q23.0-Q23.8)
  • •This is an unspecified code and should be avoided when more detailed documentation is available
