Rheumatic fever without heart involvement (I00)

The ICD-10 code I00 is used to classify rheumatic fever without heart involvement, a condition where systemic inflammation occurs due to a prior streptococcal infection but the heart is not affected. This code specifically captures cases of acute rheumatic fever presenting without cardiac complications.

This coding applies to conditions such as migratory polyarthritis, subacute rheumatic arthritis, and erythema marginatum; all recognized synonyms or related manifestations of rheumatic fever when the heart remains uninvolved. Using ICD-10 code I00 helps healthcare professionals accurately document and report cases of acute rheumatic fever where symptoms such as joint inflammation, skin rash, or pneumonitis occur without signs of rheumatic heart disease. This distinction is important for proper diagnosis, treatment planning, and epidemiological tracking. Including synonyms like recurrent rheumatic fever and subacute arthropathy supports coders in linking common terms with the official code, ensuring precise medical record-keeping.

Instructional Notations

Includes

This note appears immediately under a three character code title to further define, or give examples of, the content of the category.

  • arthritis, rheumatic, acute or subacute

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.

  • rheumatic fever with heart involvement I01.0 I01.9

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.

Rheumatic Fever

A febrile disease occurring as a delayed sequela of infections with STREPTOCOCCUS PYOGENES. It is characterized by multiple focal inflammatory lesions of the connective tissue structures, such as the heart, blood vessels, and joints (POLYARTHRITIS) and brain, and by the presence of ASCHOFF BODIES in the myocardium and skin.
