Cardiac murmurs and other cardiac sounds (R01)

The ICD-10 code R01 covers various cardiac murmurs and other cardiac sounds that are detected during clinical examinations of the heart. These codes help specify whether the heart sound is benign, unspecified, or an unusual sound distinct from typical murmurs.

Specifically, R01.0 is used for benign and innocent cardiac murmurs, often known as functional heart murmur, neonatal innocent cardiac murmur, or venous hum. These murmurs are generally harmless and commonly found in children or healthy individuals. The ICD-10 code for benign murmurs assists healthcare providers in distinguishing normal heart sounds from those that might suggest disease. The code R01.1 addresses unspecified cardiac murmurs, which include a wide range of murmurs described by their pitch, quality, timing, and intensity, such as aortic ejection murmur or mitral pansystolic murmur. This category is useful when the murmur is noted but lacks clear classification as benign or pathological. Lastly, R01.2 pertains to other abnormal cardiac sounds like split heart sounds, gallop rhythm, or prosthetic valve sounds. These unique heart sounds can indicate changes in cardiac function or structural issues and require careful documentation using this code. Together, these ICD-10 codes provide precise identifiers for specific heart sound findings, aiding both clinical assessment and accurate medical coding.
