2022 ICD-10-CM Code I44.1
Atrioventricular block, second degree
Code Classification
I44.1 is a billable diagnosis code used to specify a medical diagnosis of atrioventricular block, second degree. The code I44.1 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code I44.1 might also be used to specify conditions or terms like ekg: mobitz type ii atrioventricular block, high degree second degree atrioventricular block, intermittent second degree atrioventricular block, mobitz type i incomplete atrioventricular block, mobitz type i second degree atrioventricular block on electrocardiogram , mobitz type ii atrioventricular block, etc.
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code I44.1:
Inclusion Terms
Inclusion TermsThese terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Atrioventricular block, type I and II
- Möbitz block, type I and II
- Second degree block, type I and II
- Wenckebach's block

Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code I44.1 is grouped in the following groups for version MS-DRG V39.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2021 through 09/30/2022.
| MS-DRG | MS-DRG Title | MCD | Relative Weight |
|---|---|---|---|
| 308 | CARDIAC ARRHYTHMIA AND CONDUCTION DISORDERS WITH MCC | 05 | 1.1993 |
| 309 | CARDIAC ARRHYTHMIA AND CONDUCTION DISORDERS WITH CC | 05 | 0.7494 |
| 310 | CARDIAC ARRHYTHMIA AND CONDUCTION DISORDERS WITHOUT CC/MCC | 05 | 0.5584 |
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.
Convert I44.1 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code I44.1 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
Arrhythmia
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. The most common type of arrhythmia is atrial fibrillation, which causes an irregular and fast heart beat.
Many factors can affect your heart's rhythm, such as having had a heart attack, smoking, congenital heart defects, and stress. Some substances or medicines may also cause arrhythmias.
Symptoms of arrhythmias include
- Fast or slow heart beat
- Skipping beats
- Lightheadedness or dizziness
- Chest pain
- Shortness of breath
- Sweating
Your doctor can run tests to find out if you have an arrhythmia. Treatment to restore a normal heart rhythm may include medicines, an implantable cardioverter-defibrillator (ICD) or pacemaker, or sometimes surgery.
