ICD-10 code I44.1 for Atrioventricular block, second degree is a medical classification as listed by WHO under the range - Diseases of the circulatory system . Subscribe to Codify and get the code details in a flash.
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.
Other terms for a second degree AV block are Wenckebach’s and Mobitz blocks. Third degree AV block (I44.2 Atrioventricular block, complete) – No supraventricular impulses are conducted to the ventricles.

Second-degree atrioventricular (AV) block, or second-degree heart block, is a disease of the cardiac conduction system in which the conduction of atrial impulse through the AV node and/or His bundle is delayed or blocked.
I44. 2 - Atrioventricular block, complete | ICD-10-CM.
Differentiate Mobitz type 1 block from Mobitz type 2 block The hallmark of Mobitz type 1 block is the gradual prolongation of PR intervals before a block occurs. Mobitz type 2 block has constant PR intervals before blocks occur.
A hallmark of this type of second-degree AV block is that there is a pattern of conducted P waves (with a constant PR interval), followed by one or more non-conducted P waves.
High-grade AV block, also known as advanced heart block, is a form of third-degree heart block. This occurs when AV dissociation is present; however, intermittently some sinus node action potentials (P waves) are randomly conducted to the ventricles.
Third degree AV block (I44. 2 Atrioventricular block, complete) – No supraventricular impulses are conducted to the ventricles.

2nd Degree Type 2 | Mobitz II One being the rhythm is not cyclic, it does NOT have a pattern. Second, its QRS complexes will be IRREGULAR and this is the opposite for a 3rd degree heart block. Third, it can have NORMAL PR Intervals, where a 3rd degree heart block does not contain any PR Intervals.

And you can see it.
Mobitz 1 and 2 are the two forms of second-degree heart block. The difference between them is in mobitz 1 there is a gradual increase in the duration of PR interval until an impulse completely wanes off before reaching the ventricles but in mobitz 2 although the PR interval is prolonged it does not change with time.
A narrow QRS complex suggests nodal arrhythmia and likely type I block, while a wide complex indicates an infranodal location and type II block. Third degree AV block occurs when P waves are not conducted to the ventricles and an ectopic, slow escape rhythm is present.
Also called Wenckebach or Mobitz type I block, type I second-degree AV block occurs when each successive impulse from the SA node is delayed slightly longer than the previous one. This pattern of progressive prolongation of the PR interval continues until an impulse fails to be conducted to the ventricles.
This is the mildest type of heart block. Second-degree heart block is classified into two categories: Type I and Type II. In second-degree heart block, the impulses are intermittently blocked. Type I, also called Mobitz Type I or Wenckebach's AV block: This is a less serious form of second-degree heart block.
Also called Wenckebach or Mobitz type I block, type I second-degree AV block occurs when each successive impulse from the SA node is delayed slightly longer than the previous one. This pattern of progressive prolongation of the PR interval continues until an impulse fails to be conducted to the ventricles.
Mobitz type I is a type of 2nd degree AV block, which refers to an irregular cardiac rhythm (arrhythmia), that reflects a conduction block in the electrical conduction system of the heart.
There are two sub-types of second degree heart block: Mobitz type 1 - this is the least serious type of second degree heart block - it may occasionally cause symptoms of mild dizziness and does not usually require treatment.
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:

This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code I44.1 and a single ICD9 code, 426.13 is an approximate match for comparison and conversion purposes.
