Acute rheumatic heart disease, unspecified

This code represents an acute inflammatory process affecting the heart, specifically the heart valves, myocardium, or pericardium, as a sequela of rheumatic fever. The specific cardiac structure involved is not documented or is unknown. It signifies active rheumatic carditis without further specification of the affected heart structures.

Use this code when documentation clearly indicates acute rheumatic heart disease, but the specific type (e.g., pericarditis, endocarditis, myocarditis) is not specified. This code is appropriate when the provider diagnoses "acute rheumatic carditis, unspecified" or "acute rheumatic heart disease, NOS."

• Do not use this code if the specific cardiac involvement (e.g., acute rheumatic pericarditis, endocarditis, or myocarditis) is documented; instead, use the more specific I01.0-I01.2 codes.
• This code should be sequenced as a primary diagnosis when the acute rheumatic heart disease is the reason for the encounter.
• Ensure documentation supports an acute process, not chronic rheumatic heart disease, which is coded differently.
