ICD10 code of Maple syrup urine disease and ICD9 code

TL;DR: Maple syrup urine disease is classified under the ICD-10 code E71.0 and the ICD-9 code 270.3. These diagnostic codes are essential for medical record-keeping, insurance billing, and ensuring patients receive specialized metabolic care for this rare genetic disorder.

What is the clinical significance of the diagnostic codes for Maple syrup urine disease?

In the global healthcare system, standardized coding is vital for tracking the prevalence and management of rare conditions. Maple syrup urine disease (MSUD) is a metabolic disorder characterized by the body's inability to break down specific branched-chain amino acids (leucine, isoleucine, and valine). Using the correct ICD-10 code (E71.0) and ICD-9 code (270.3) helps clinicians and hospitals accurately categorize Maple syrup urine disease, which ensures that patients are correctly identified for newborn screening follow-ups and specialized dietary management protocols.

How is Maple syrup urine disease classified and diagnosed?

Maple syrup urine disease is an autosomal recessive metabolic condition. Diagnosis typically begins with newborn screening, which identifies elevated levels of leucine in the blood. When a diagnosis is confirmed, medical professionals use the E71.0 code to document the condition. Because Maple syrup urine disease can lead to severe neurological complications if left untreated, rapid identification and the use of precise diagnostic coding are critical for initiating immediate metabolic intervention.

What are the primary clinical features of Maple syrup urine disease?

Individuals with Maple syrup urine disease require lifelong management to prevent the accumulation of toxic byproducts. The condition is named for the characteristic sweet odor of the urine, which resembles maple syrup. Clinically, the disease presents in several forms, ranging from classic severe forms to milder, intermittent variants. Key clinical features include:

• Sweet-smelling earwax and urine (due to the presence of sotolone).


• Poor feeding and lethargy in neonates.


• Developmental delays if metabolic control is not maintained.


• Acute metabolic crises triggered by illness or physical stress.


• Severe neurological symptoms, including seizures and coma, if leucine levels are not strictly regulated.

Is there support for those living with Maple syrup urine disease?

Living with a rare metabolic condition can be isolating, but you are not alone. Currently, 82 people with Maple syrup urine disease have joined the DiseaseMaps.org community to share their experiences, offer support, and discuss the daily realities of protein-restricted diets and metabolic monitoring. Connecting with others who navigate the same medical codes and dietary challenges can be an invaluable part of your journey in managing Maple syrup urine disease.

Next steps

• Consult with a metabolic specialist or a clinical geneticist to ensure your medical records accurately reflect your diagnosis using the appropriate E71.0 code.


• Work with a specialized metabolic dietitian to maintain a protein-controlled diet tailored to your specific amino acid levels.


• Join the DiseaseMaps.org community to connect with other families and individuals affected by Maple syrup urine disease.


• Regularly monitor blood amino acid levels as directed by your metabolic team to prevent acute crises.
