Benign neoplasm of heart

This code signifies the presence of a non-cancerous tumor originating within the heart muscle, valves, or lining. These benign growths do not spread to other parts of the body but can still impact cardiac function depending on their size and location.

Assign this code when medical record documentation clearly identifies a benign neoplasm located within any part of the heart. This diagnosis is typically supported by imaging studies such as echocardiograms, CT scans, or MRI, along with pathology reports if a biopsy or surgical excision was performed.

• Ensure the documentation explicitly states "benign" and "heart" to differentiate from malignant or uncertain neoplasms.
• Carefully review imaging and pathology reports for the precise anatomical location within the heart.
• Remember the Excludes1 note; do not code this with D21.3 (benign neoplasm of great vessels).
