Manifestations range from subclinical to sudden death (DEATH, SUDDEN). Myocarditis in association with cardiac dysfunction is classified as inflammatory CARDIOMYOPATHY usually caused by INFECTION, autoimmune diseases, or responses to toxic substances. Myocarditis is also a common cause of DILATED CARDIOMYOPATHY and other cardiomyopathies. 429.0 is a specific code that can be used to specify a diagnosis 429.0 contains 12 index entries ICD-9-CM Diagnosis 429.1 Myocardial degeneration A group of diseases in which the dominant feature is the involvement of the CARDIAC MUSCLE itself. Cardiomyopathies are classified according to their predominant pathophysiological features (DILATED CARDIOMYOPATHY; HYPERTROPHIC CARDIOMYOPATHY; RESTRICTIVE CARDIOMYOPATHY) or their etiological/pathological factors (CARDIOMYOPATHY, ALCOHOLIC; ENDOCARDIAL FIBROELASTOSIS). 429.1 is a specific code that can be used to specify a diagnosis 429.1 contains 45 index entries ICD-9-CM Diagnosis 429.2 Cardiovascular disease unspecified A non-neoplastic or neoplastic disorder affecting the heart or the vessels (arteries, veins and lymph vessels). Representative examples of non-neoplastic cardiovascular disorders are endocarditis and hypertension. Representative examples of neoplastic cardiovascular disorders are endocardial myxoma and angiosarcoma. -- 2003 429.2 is a specific code that can be used to specify a diagnosis 429.2 contains 11 index entries ICD-9-CM Diagnosis 429.3 Cardiomegaly Enlargement of the HEART due to chamber HYPERTROPHY, an increase in wall thickness without an increase in the number of cells (MYOCYTES, CARDIAC). It is the result of increase in myocyte size, mitochondrial and myofibrillar mass, as well as changes in extracellular matrix. Enlargement of the HEART, usually indicated by a cardiothoracic ratio above 0.50. Heart enlargement may involve the right, the left, or both HEART VENTRICLES or HEART ATRIA. Cardiomegaly is a nonspecific symptom seen in patients with chronic systolic heart failure (HEART FAILURE, CONGESTIVE) or several forms of CARDIOMYOPATHIES. 429.3 is a specific code that can be used to specify a diagnosis 429.3 contains 10 index entries ICD-9-CM Diagnosis 429.4 Functional disturbances following cardiac surgery A febrile illness associated with pericardial and sometimes pleuropulmonary reaction that often follows extensive pericardiotomy. 429.4 is a specific code that can be used to specify a diagnosis 429.4 contains 35 index entries ICD-9-CM Diagnosis 429.5 Rupture of chordae tendineae 429.5 is a specific code that can be used to specify a diagnosis 429.5 contains 3 index entries ICD-9-CM Diagnosis 429.6 Rupture of papillary muscle 429.6 is a specific code that can be used to specify a diagnosis 429.6 contains 1 index entry ICD-9-CM Diagnosis 429.7 Certain sequelae of myocardial infarction not elsewhere classified 429.7 is a non-specific code that cannot be used to specify a diagnosis ICD-9-CM Diagnosis 429.71 Certain sequelae of myocardial infarction not elsewhere classified acquired cardiac septal defect 429.71 is a specific code that can be used to specify a diagnosis 429.71 contains 13 index entries ICD-9-CM Diagnosis 429.79 Certain sequelae of myocardial infarction not elsewhere classified other 429.79 is a specific code that can be used to specify a diagnosis 429.79 contains 1 index entry ICD-9-CM Diagnosis 429.8 Other ill-defined heart diseases 429.8 is a non-specific code that cannot be used to specify a diagnosis ICD-9-CM Diagnosis 429.81 Other disorders of papillary muscle 429.81 is a specific code that can be used to specify a diagnosis 429.81 contains 8 index entries ICD-9-CM Diagnosis 429.82 Hyperkinetic heart disease 429.82 is a specific code that can be used to specify a diagnosis 429.82 contains 6 index entries ICD-9-CM Diagnosis 429.89 Other ill-defined heart diseases 429.89 is a specific code that can be used to specify a diagnosis 429.89 contains 20 index entries ICD-9-CM Diagnosis 429.9 Heart disease unspecified 429.9 is a specific code that can be used to specify a diagnosis 429.9 contains 11 index entries
