Rheumatic disorders of both mitral and tricuspid valves

This diagnosis code signifies the presence of rheumatic disease affecting both the mitral and tricuspid heart valves simultaneously. This condition typically results from acute rheumatic fever, leading to inflammation and damage that can cause stenosis, regurgitation, or a combination of both in these valves.

Use this code when documentation explicitly states rheumatic involvement of both the mitral and tricuspid valves. This often occurs in patients with a history of rheumatic fever presenting with symptoms of combined valvular dysfunction, such as dyspnea, fatigue, or heart murmurs indicative of both mitral and tricuspid valve pathology.

• Ensure the documentation specifies "rheumatic" etiology for both valves; otherwise, use codes for non-rheumatic combined valvular disorders.
• Do not use this code if only one valve is affected by rheumatic disease; instead, select the appropriate code for single-valve rheumatic disorder.
• Sequence this code as a primary diagnosis when it is the main reason for the encounter, or as a secondary diagnosis when it contributes to the patient's overall condition.
