When a Pacemaker Is Needed for a Heart Block
Third-degree atrioventricular (AV) block, also referred to as third-degree heart block or complete heart block (CHB), is an abnormal heart rhythm resulting from a defect in the cardiac conduction system in which there is no conduction through the atrioventricular node (AVN), leading to complete dissociation of the atria and ventricles. [1, 2] The ventricular escape mechanism can occur anywhere ...
In complete heart block, there is complete absence of AV conduction, with none of the supraventricular impulses conducted to the ventricles. The perfusing rhythm is maintained by junctional or ventricular escape rhythm. Alternatively, the patient may suffer ventricular standstill leading to syncope (if self-terminating) or sudden cardiac death (if prolonged).
Treatment of Second-Degree AV Block Type II
I44. 2 - Atrioventricular block, complete | ICD-10-CM.
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.
Q24. 6 - Congenital heart block | ICD-10-CM.
426.12 - Mobitz (type) II atrioventricular block.
Heart block is a problem with your heart's electrical system, which makes your heart beat and controls your heart rate and rhythm. The condition is also called atrioventricular (AV) block or a conduction disorder.
Third-degree heart block is also referred to as complete heart block and is a serious condition. None of the electrical impulses that originate in the atria reach the ventricles.
ICD-10-CM is a seven-character, alphanumeric code. Each code begins with a letter, and that letter is followed by two numbers. The first three characters of ICD-10-CM are the “category.” The category describes the general type of the injury or disease. The category is followed by a decimal point and the subcategory.
An electrocardiogram (ECG) is the main test used to diagnose heart block. It measures the electrical activity of your heart. An ECG can be carried out at rest or while you're exercising. Your doctor may ask you to wear a portable ECG monitor to get a reading over time.

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.
1 Atrioventricular block, second degree.
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.
A blockage of electrical conduction within the sinoatrial node resulting in the failure of impulse transmission from the sinoatrial node.
The 2022 edition of ICD-10-CM I45.5 became effective on October 1, 2021.
I44.2 is a valid billable ICD-10 diagnosis code for Atrioventricular block, complete . It is found in the 2021 version of the ICD-10 Clinical Modification (CM) and can be used in all HIPAA-covered transactions from Oct 01, 2020 - Sep 30, 2021 .
When an Excludes2 note appears under a code it is acceptable to use both the code and the excluded code together. A “code also” note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction. The sequencing depends on the circumstances of the encounter.
DO NOT include the decimal point when electronically filing claims as it may be rejected. Some clearinghouses may remove it for you but to avoid having a rejected claim due to an invalid ICD-10 code, do not include the decimal point when submitting claims electronically. See also: Block, blocked.
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:

Assign code V53.31, Fitting and adjustment of other device, Cardiac device, cardiac pacemaker, as an additional code assignment. A code is not assigned for sick sinus syndrome when it is being controlled by the pacemaker and no problems are detected during the check. Interrogation is a routine check, which is done via computer to assess pacemaker function. The pacemaker is routinely evaluated to ensure the device is programmed accurately as well as to assess battery and lead function. Pacemaker settings may be reprogrammed, if required. Interrogation of the device can be done in the inpatient setting or in the office setting.
Not billing the complete heart block would affect the patient's risk score just as with the sick sinus syndrome.
