Other disorders of propionate metabolism
ICD-10 E71.128 is a billable code used to indicate a diagnosis of other disorders of propionate metabolism.
E71.128 refers to a group of metabolic disorders characterized by the abnormal metabolism of propionate, a short-chain fatty acid. These disorders are often due to enzyme deficiencies that disrupt the normal catabolism of propionate, leading to its accumulation in the body. Commonly associated conditions include propionic acidemia, which results from a deficiency in the enzyme propionyl-CoA carboxylase. This enzyme is crucial for converting propionyl-CoA to methylmalonyl-CoA, a key step in the metabolism of certain amino acids and odd-chain fatty acids. Symptoms of propionic acidemia can include metabolic acidosis, developmental delays, and neurological impairments. Diagnosis typically involves biochemical testing to measure organic acids in urine and plasma, alongside genetic testing to identify specific enzyme deficiencies. Management often requires dietary modifications to limit protein intake and the use of supplements to manage metabolic derangements. Early diagnosis and intervention are critical to improving outcomes and preventing severe complications.
Detailed family history, genetic test results, and clinical findings.
Patients presenting with developmental delays and metabolic acidosis.
Ensure genetic counseling is documented, as it is crucial for understanding inheritance patterns.
Growth charts, developmental assessments, and dietary management plans.
Infants with failure to thrive and unexplained metabolic crises.
Documenting dietary restrictions and metabolic management strategies is essential.
Used when genetic confirmation of propionic acidemia is needed.
Document the reason for genetic testing and results.
Genetic counseling should be documented as part of the testing process.
Common symptoms include metabolic acidosis, vomiting, lethargy, developmental delays, and neurological impairments. Symptoms can vary widely based on the specific disorder and the age of onset.
