R90-R94: Abnormal findings on diagnostic imaging and in function studies, without diagnosis

R94: Abnormal results of function studies

Abnormal results of function studies, classified under the ICD-10 code group R94, refer to a range of conditions identified when the functioning of specific body systems isn't operating as expected. These irregular results can be discovered during tests of the nervous, cardiovascular, digestive, or respiratory systems, among others. The abnormalities might be symptoms of various underlying disorders or diseases, with the specific cause depending on the affected system. Common signs include unexpected changes in body functions like heart rate, breathing, digestion, or sensation. Disease progression is also varied and depends on the underlying condition leading to the abnormal result. As these are usually diagnostic findings rather than standalone diseases, they may require further investigation to identify the root cause of the anomaly. Since this group of conditions covers a vast array of potential issues, it is vital to understand each might have different causes, symptoms and disease progression.
