Rheumatic fever with heart involvement (I01)
ICD-10 codes I01 and its subcodes are used to classify cases of rheumatic fever with heart involvement. These codes specifically identify different types of acute rheumatic heart disease affecting the heart's layers, including the pericardium, endocardium, and myocardium.
These codes help healthcare providers document and code conditions such as acute rheumatic pericarditis (I01.0), known also as acute rheumatic heart disease or acute rheumatic fever affecting the pericardium; acute rheumatic endocarditis (I01.1), which includes acute rheumatic carditis and valvulitis affecting the heart’s inner lining; and acute rheumatic myocarditis (I01.2), which impacts the heart muscle itself. The section also covers other acute rheumatic heart diseases (I01.8), such as pancarditis including MacCallum’s patch, and unspecified acute rheumatic heart disease (I01.9). Using these specific codes ensures accurate identification of rheumatic fever’s cardiac manifestations, supporting clinical decisions and medical billing. This section is essential when searching for the ICD-10 code for rheumatic fever with heart involvement and its variants.
Instructional Notations
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Rheumatoid Vasculitis
Necrotizing VASCULITIS of small and medium size vessels, developing as a complication in RHEUMATOID ARTHRITIS patients. It is characterized by peripheral vascular lesions, cutaneous ULCERS, peripheral GANGRENE, and MONONEURITIS MULTIPLEX.
