Other right bundle-branch block

This code represents a conduction abnormality within the heart's electrical system, specifically affecting the right bundle branch, but not meeting the criteria for a complete right bundle-branch block. It indicates a partial or atypical disruption of electrical impulse transmission through the right ventricle.

Use this code when diagnostic testing, typically an electrocardiogram (ECG), reveals findings consistent with an incomplete or unspecified right bundle-branch block. Documentation should clearly state "other right bundle-branch block," "incomplete right bundle-branch block," or similar terminology that does not specify a complete block.

• Differentiate carefully between "other right bundle-branch block" and complete right bundle-branch block (I45.0).
• Ensure the physician's documentation explicitly supports an "other" or "incomplete" classification, rather than a full block.
• Avoid using this code if the documentation specifies a complete right bundle-branch block, even if it's transient or intermittent.
