What ICD-10 Codes Are Used for Heart Block?

Heart Block, a condition where the heart's electrical signals are interrupted or slowed down, has various specific codes. Below are some Heart Block ICD codes:

• I44.0: Atrioventricular block, first degree
• I44.1: Atrioventricular block, second degree
• I44.2: Atrioventricular block, complete
• I44.3: Other and unspecified atrioventricular block
• I44.4: Left anterior fascicular block
• I44.5: Left posterior fascicular block
• I44.6: Other and unspecified fascicular block
• I44.7: Left bundle-branch block
• I45.10: Unspecified bundle-branch block

These codes allow clinicians to diagnose and treat the various forms of Heart Block accurately.

Clinical Information

Heart Block refers to a delay or obstruction in the heart's electrical pathways. Here's a detailed look at its clinical aspects:

• It may be congenital or acquired
• Symptoms include dizziness, fainting, fatigue, and palpitations
• Divided into degrees and types based on the severity
• First-degree is a delay without missing beats
• Second-degree misses some beats
• Third-degree, or complete block, requires immediate treatment
• Treatment may include medications or pacemaker implantation

Synonyms Include:

• Atrioventricular block
• Bundle-branch block
• AV block
• Cardiac block
• Electrical heart block
