Atrioventricular (AV) block involves impairment of the conduction between the atria and ventricles of the heart. In ICD-10-CM the codes are categorized by degree: First degree AV block (I44.0 Atrioventricular block, first degree) – All atrial impulses reach the ventricles, but the conduction is delayed within the AV node.
I44.0 is a valid billable ICD-10 diagnosis code for Atrioventricular block, first degree . It is found in the 2022 version of the ICD-10 Clinical Modification (CM) and can be used in all HIPAA-covered transactions from Oct 01, 2021 - Sep 30, 2022 .
Atrioventricular (AV) block involves impairment of the conduction between the atria and ventricles of the heart. In ICD-10-CM the codes are categorized by degree:
First degree AV block (I44.0 Atrioventricular block, first degree) – All atrial impulses reach the ventricles, but the conduction is delayed within the AV node. Patients are generally asymptomatic and the first-degree AV block is usually an incidental finding on electrocardiography (ECG).

Although first-degree AV block is not an absolute contraindication for administration of drugs such as calcium channel blockers, beta-blockers, digoxin, and amiodarone, extreme caution should be exercised in the use of these medications in patients with first-degree AV block.
Atrioventricular (AV) block is an interruption or delay of electrical conduction from the atria to the ventricles due to conduction system abnormalities in the AV node or the His-Purkinje system. Conduction delay or block can be physiologic if the atrial rate is abnormally fast or pathologic at normal atrial rates.
Complete heart block is the most serious type of AV heart block. It happens when the electrical impulses that tell your heart when to beat don't pass between the top (atria) and bottom chambers (ventricles) of your heart. This can affect the flow of blood to your body and brain.

Background: Beta-blockers, verapamil, and diltiazem are considered a cause of AV block for which pacemaker implantation is not indicated. However, it is not known if such patients can expect a benign course after discontinuation of the culprit medication.

First-degree atrioventricular (AV) block is a condition of abnormally slow conduction through the AV node. It is defined by ECG changes that include a PR interval of greater than 0.20 without disruption of atrial to ventricular conduction. This condition is generally asymptomatic and discovered only on routine ECG.
Understanding Atrioventricular BlockFirst-degree atrioventricular block. The P waves are buried within the T waves. ... Second-degree AV Block – Mobitz type I. ... Second degree AV block – Mobitz type II. ... Third-degree AV block (complete heart block).
In general, no treatment is required for first-degree AV block unless prolongation of the PR interval is extreme (>400 ms) or rapidly evolving, in which case pacing is indicated. Prophylactic antiarrhythmic drug therapy is best avoided in patients with marked first-degree AV block.
Common drugs that are known to cause AV block include beta-blockers, digoxin, calcium channel blockers, and many antiarrhythmic agents.
The medications that most commonly cause first-degree heart block are those that increase the refractory time of the AV node, thereby slowing AV conduction. These include calcium channel blockers, beta-blockers, cardiac glycosides, and anything that increases cholinergic activity such as cholinesterase inhibitors.
In general, no treatment is required for first-degree AV block unless prolongation of the PR interval is extreme (>400 ms) or rapidly evolving, in which case pacing is indicated. Prophylactic antiarrhythmic drug therapy is best avoided in patients with marked first-degree AV block.
Get regular exercise. Try for 2½ hours a week. If you do not have other heart problems, you likely do not have limits on the type or level of activity that you can do. You may want to walk, swim, bike, or do other activities.
Atrioventricular (AV) block involves impairment of the conduction between the atria and ventricles of the heart. In ICD-10-CM the codes are categorized by degree:#N#First degree AV block (I44.0 Atrioventricular block, first degree) – All atrial impulses reach the ventricles, but the conduction is delayed within the AV node. Patients are generally asymptomatic and the first-degree AV block is usually an incidental finding on electrocardiography (ECG). People with newly diagnosed first-degree AV block may be well-conditioned athletes, or they may have a history of myocardial infarction or myocarditis. First-degree AV block also may represent the first sign of degenerative processes of the AV conduction system.#N#Second degree AV block (I44.1 Atrioventricular block, second degree) – Atrial impulses fail to conduct to the ventricles. Patients may be asymptomatic, but may experience pre-syncope or syncope and sensed irregular heartbeats. The latter usually is observed in more advanced conduction disturbances, such as Mobitz II second-degree AV block. A history of medications that affect atrioventricular node (AVN) function (e.g., digitalis, beta-blockers, and calcium channel blockers) may be contributory and should be obtained. Other terms for a second degree AV block are Wenckebach’s and Mobitz blocks.#N#Third degree AV block (I44.2 Atrioventricular block, complete) – No supraventricular impulses are conducted to the ventricles. Patients have symptoms of fatigue, dizziness, light-headedness, pre-syncope, or syncope. Syncopal episodes due to slow heart rates are called Morgagni-Adams-Stokes (MAS) episodes, in recognition of the pioneering work of these researchers on syncope. Patients with third-degree AV block may have associated symptoms of acute myocardial infarction either causing the block or related to reduced cardiac output from bradycardia in the setting of advanced atherosclerotic coronary artery disease.#N#Proper coding of AV block requires documentation of severity:
PROCEDURE: Insertion of right atrial and right ventricular transvenous leads through the left subclavian vein and implantation of a dual-chamber permanent pacemaker.

426.11 is a legacy non-billable code used to specify a medical diagnosis of first degree atrioventricular block. This code was replaced on September 30, 2015 by its ICD-10 equivalent.
The following crosswalk between ICD-9 to ICD-10 is based based on the General Equivalence Mappings (GEMS) information:
References found for the code 426.11 in the Index of Diseases and Injuries:
An arrhythmia is a problem with the rate or rhythm of your heartbeat. It means that your heart beats too quickly, too slowly, or with an irregular pattern. When the heart beats faster than normal, it is called tachycardia. When the heart beats too slowly, it is called bradycardia.
General Equivalence Map Definitions The ICD-9 and ICD-10 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.
