2021 ICD-10-CM Code I45.19

Code Classification

• Diseases of the circulatory system (I00–I99)
  • Other forms of heart disease (I30-I52)
    • Other conduction disorders (I45)

Code Edits

The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10 Code Edits are applicable to this code:

• Questionable admission codes - Some diagnoses are not usually sufficient justification for admission to an acute care hospital. For example, if a patient is given code R030 for elevated blood pressure reading, without diagnosis of hypertension, then the patient would have a questionable admission, since elevated blood pressure reading is not normally sufficient justification for admission to a hospital. The following list contains diagnosis codes identified as questionable admission when used.

Clinical Information

• BUNDLE BRANCH BLOCK-. a form of heart block in which the electrical stimulation of heart ventricles is interrupted at either one of the branches of bundle of his thus preventing the simultaneous depolarization of the two ventricles.
• BRUGADA SYNDROME-. an autosomal dominant defect of cardiac conduction that is characterized by an abnormal st segment in leads v1 v3 on the electrocardiogram resembling a right bundle branch block; high risk of ventricular tachycardia; or ventricular fibrillation; syncopal episode; and possible sudden death. this syndrome is linked to mutations of gene encoding the cardiac sodium channel alpha subunit.

Diagnostic Related Groups - MS-DRG Mapping

The ICD-10 code I45.19 is grouped in the following groups for version MS-DRG V38.0 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 10/01/2020 through 09/30/2021.

• 308 - CARDIAC ARRHYTHMIA AND CONDUCTION DISORDERS WITH MCC - Relative Weight: 1.1993
• 309 - CARDIAC ARRHYTHMIA AND CONDUCTION DISORDERS WITH CC - Relative Weight: 0.7494
• 310 - CARDIAC ARRHYTHMIA AND CONDUCTION DISORDERS WITHOUT CC/MCC - Relative Weight: 0.5584

Convert I45.19 to ICD-9 Code

The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code I45.19 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.

• 426.4 - Rt bundle branch block (Approximate Flag)
