Benign and innocent cardiac murmurs

This code signifies the presence of non-pathological heart sounds, often described as "flow murmurs," that are not indicative of underlying structural heart disease or hemodynamic compromise. These murmurs are typically soft, systolic, and change with position or respiration, representing normal blood flow dynamics.

Use this code when documentation explicitly states "benign murmur," "innocent murmur," or describes a murmur with characteristics consistent with a non-pathological origin, particularly in pediatric patients or young adults. This code is appropriate when a thorough cardiac evaluation has ruled out structural heart disease.

• Do not use this code if there is any indication of underlying cardiac pathology, even if the murmur is described as "mild."
• Ensure documentation clearly distinguishes between benign murmurs and those requiring further investigation or representing a pathological condition.
• Avoid using this code as a primary diagnosis if a more specific cardiac condition is identified, even if a benign murmur is also present.
