Other atrioventricular block

This code represents an unspecified type of atrioventricular (AV) block that is not first-degree, second-degree Mobitz type I (Wenckebach), or second-degree Mobitz type II. It indicates a delay or interruption in the electrical impulse conduction from the atria to the ventricles that doesn't fit into the more specific categories of AV block. This can manifest as various degrees of heart block beyond the commonly classified types.

Use this code when the medical record clearly documents an AV block, but the specific type is not precisely identified as first-degree, Mobitz I, or Mobitz II. This code is appropriate when the physician's diagnosis is simply "other AV block" or "unspecified AV block" after ruling out the more common forms. Documentation should include ECG findings or physician notes indicating an AV conduction disturbance that doesn't fit other I44.x categories.

• Do not use this code if a more specific type of AV block (e.g., first-degree, Mobitz I, Mobitz II) is documented.
• Review ECG reports and physician notes carefully to identify the precise type of AV block before defaulting to this code.
• Consider querying the provider for clarification if the documentation is ambiguous regarding the specific type of AV block.
