Code Description

ICD-10 E71.19 is a billable code used to indicate a diagnosis of other disorders of branched-chain amino-acid metabolism.

Key Diagnostic Point:

E71.19 encompasses a variety of metabolic disorders characterized by the abnormal metabolism of branched-chain amino acids (BCAAs), which include leucine, isoleucine, and valine. These amino acids are essential for protein synthesis and energy production. Disorders in this category may arise from enzyme deficiencies, such as branched-chain alpha-keto acid dehydrogenase complex deficiency, leading to the accumulation of toxic metabolites. Symptoms can vary widely, ranging from metabolic crises in infancy to neurological deficits and developmental delays in later life. Diagnosis typically involves biochemical testing to measure amino acid levels in blood and urine, alongside genetic testing to identify specific enzyme deficiencies. Management often includes dietary modifications to restrict BCAA intake and supplementation with other amino acids to prevent complications. Early diagnosis and intervention are crucial to improve outcomes and prevent severe neurological damage.
