I45.5

What This Code Means

This code describes a type of heart rhythm problem where electrical signals don't travel properly through the heart, but it doesn't fit into the more common categories of heart block. It's a catch-all category for unusual or specific types of conduction problems in the heart.

Coding Tips

• •Use this code only when the heart block type is specified in the documentation but doesn't match I45.0-I45.4 categories (first degree, second degree, or complete heart block)
• •Always review the provider's documentation carefully to ensure a more specific heart block code isn't applicable before assigning this 'other specified' code
