2006 ICD-9-CM Volume 1 Diagnosis Codes Home > Diseases Of The Circulatory System 390-459 > Other Forms Of Heart Disease 420-429 > ICD-9-CM Diagnosis 427 Cardiac dysrhythmias Any variation from the normal rhythm or rate of the heart beat. An abnormal rate of muscle contractions in the heart. 427 is a non-specific code that cannot be used to specify a diagnosis ICD-9-CM Diagnosis 427.0 Paroxysmal supraventricular tachycardia 427.0 is a specific code that can be used to specify a diagnosis 427.0 contains 11 index entries ICD-9-CM Diagnosis 427.1 Paroxysmal ventricular tachycardia An abnormally rapid ventricular rhythm with wide QRS complexes, usually in excess of 150 per minute. It is generated within the ventricle, below the BUNDLE OF HIS, and is most commonly associated with atrioventricular dissociation. 427.1 is a specific code that can be used to specify a diagnosis 427.1 contains 5 index entries ICD-9-CM Diagnosis 427.2 Paroxysmal tachycardia unspecified Condition marked by attacks of rapid action of the heart having sudden onset and cessation. 427.2 is a specific code that can be used to specify a diagnosis 427.2 contains 8 index entries ICD-9-CM Diagnosis 427.3 Atrial fibrillation and flutter 427.3 is a non-specific code that cannot be used to specify a diagnosis ICD-9-CM Diagnosis 427.31 Atrial fibrillation Disorder of cardiac rhythm characterized by rapid, irregular atrial impulses and ineffective atrial contractions. 427.31 is a specific code that can be used to specify a diagnosis 427.31 contains 2 index entries ICD-9-CM Diagnosis 427.32 Atrial flutter Rapid, irregular atrial contractions due to an abnormality of atrial excitation. 427.32 is a specific code that can be used to specify a diagnosis 427.32 contains 4 index entries ICD-9-CM Diagnosis 427.4 Ventricular fibrillation and flutter 427.4 is a non-specific code that cannot be used to specify a diagnosis ICD-9-CM Diagnosis 427.41 Ventricular fibrillation 427.41 is a specific code that can be used to specify a diagnosis 427.41 contains 3 index entries ICD-9-CM Diagnosis 427.42 Ventricular flutter 427.42 is a specific code that can be used to specify a diagnosis 427.42 contains 2 index entries ICD-9-CM Diagnosis 427.5 Cardiac arrest Cessation of the heart beat. 427.5 is a specific code that can be used to specify a diagnosis 427.5 contains 8 index entries ICD-9-CM Diagnosis 427.6 Premature beats A premature contraction of the heart that is initiated somewhere other than the sinoatrial node. 427.6 is a non-specific code that cannot be used to specify a diagnosis ICD-9-CM Diagnosis 427.60 Premature beats unspecified A premature contraction of the heart that is initiated somewhere other than the sinoatrial node. 427.60 is a specific code that can be used to specify a diagnosis 427.60 contains 14 index entries ICD-9-CM Diagnosis 427.61 Supraventricular premature beats Premature contractions of the heart arising from an ectopic atrial focus. With ventricular premature complexes, they represent one of the most common causes of irregular pulse. They are more apt to occur if there is atrial or conduction system disease such as left atrial enlargement in mitral stenosis. In community prospective studies, atrial premature complexes are not related to sudden death, as are ventricular premature beats in coronary disease. 427.61 is a specific code that can be used to specify a diagnosis 427.61 contains 15 index entries ICD-9-CM Diagnosis 427.69 Other premature beats 427.69 is a specific code that can be used to specify a diagnosis 427.69 contains 10 index entries ICD-9-CM Diagnosis 427.8 Other specified cardiac dysrhythmias 427.8 is a non-specific code that cannot be used to specify a diagnosis ICD-9-CM Diagnosis 427.81 Sinoatrial node dysfunction Dysfunction of the sinoatrial node manifested by persistent sinus bradycardia, sinus arrest, sinoatrial exit block, chronic atrial fibrillation and inability of the heart to resume sinus rhythm following cardioversion for atrial fibrillation. 427.81 is a specific code that can be used to specify a diagnosis 427.81 contains 18 index entries ICD-9-CM Diagnosis 427.89 Other specified cardiac dysrhythmias A premature contraction of the heart that is initiated somewhere other than the sinoatrial node. Nodal arrhythmia is arrythmia occurring when the atrioventricular node or surrounding junctional tissue is acting as pacemaker. 427.89 is a specific code that can be used to specify a diagnosis 427.89 contains 45 index entries ICD-9-CM Diagnosis 427.9 Cardiac dysrhythmia unspecified An abnormal rate of muscle contractions in the heart. Any variation from the normal rhythm or rate of the heart beat. 427.9 is a specific code that can be used to specify a diagnosis 427.9 contains 12 index entries
