Other cardiac sounds

This code represents the presence of abnormal or unusual heart sounds detected during a cardiac examination that are not classified as murmurs. These sounds may include clicks, rubs, or gallops, indicating underlying cardiac dysfunction or structural abnormalities.

Use this code when documentation specifies the presence of abnormal cardiac sounds such as a pericardial rub, ejection click, opening snap, or S3/S4 gallop, without further specification as a murmur. This code is appropriate when the physician explicitly identifies and documents these distinct sounds.

• Do not use this code if the documentation specifies a heart murmur; instead, refer to codes in category I34 (Nonrheumatic mitral valve disorders) or I35 (Nonrheumatic aortic valve disorders) as appropriate.
• Always seek further specificity from the provider if the documentation broadly states "abnormal heart sounds" without identifying the specific type.
• This code is often a sign or symptom and may require an additional code for the underlying definitive diagnosis if known.
