Before antibiotics became so common, this was often a widely-seen cause of valve disorders. Heart valves can become swollen and scarred when they're attacked by strep antibodies. This makes the valves susceptible to insufficiency or stenosis. That background information is important for you to know, because ICD-9 provides different codes based on whether the valve disorder is associated with rheumatic fever. The fourth digit is necessary to differentiate between a possible diagnosis of 395.0 and 395.2 (Rheumatic aortic stenosis [...]
