Other heart block

This code represents a type of cardiac conduction disturbance where electrical signals from the atria to the ventricles are partially or completely blocked, but the specific type of block does not fit into other defined categories (e.g., first-degree, second-degree Mobitz I or II, or complete AV block). It indicates an unspecified or atypical form of atrioventricular (AV) block.

Use this code when documentation clearly states "other heart block" or describes an AV block that doesn't precisely fit the criteria for more specific types. This code is appropriate when the physician's diagnosis is a heart block, but further specificity regarding the degree or type is not provided or is atypical.

• Avoid using this code if a more specific type of AV block (e.g., first-degree, Mobitz I, Mobitz II, complete) is documented.
• Query the provider for clarification if "heart block" is documented without further specification to determine if a more precise code can be assigned.
• Consider sequencing this code after any underlying cardiac conditions that may be contributing to the heart block.
