Typhoid fever with heart involvement

This code signifies a systemic infection caused by Salmonella Typhi that has specifically manifested with cardiac complications. This includes conditions such as myocarditis, pericarditis, or endocarditis directly attributable to the typhoid infection. It indicates that the heart is an organ system affected by the severe bacterial illness.

Use this code when documentation clearly states a diagnosis of typhoid fever and explicitly links it to cardiac involvement. This typically occurs in severe cases where the infection has spread beyond the gastrointestinal tract, and diagnostic tests or clinical findings confirm heart-related pathology. Supporting documentation would include physician notes detailing cardiac symptoms, EKG changes, echocardiogram findings, or elevated cardiac enzymes in the context of confirmed typhoid.

• Ensure the medical record explicitly states "with heart involvement" or specifies a cardiac complication (e.g., myocarditis, endocarditis) directly caused by typhoid fever.
• Do not use this code if cardiac issues are coincidental or due to a separate, unrelated condition.
• Consider sequencing this code as the primary diagnosis if the heart involvement is the main reason for the encounter or the most severe manifestation of the typhoid fever.
