ICD10 code of Isovaleric acidemia and ICD9 code

Isovaleric acidemia is classified under the ICD-10-CM code E71.110, while its corresponding ICD-9-CM code is 270.3. These diagnostic codes are essential for medical billing, insurance reimbursement, and tracking clinical outcomes for patients living with this rare metabolic disorder.

What is the clinical significance of Isovaleric acidemia?

Isovaleric acidemia is a rare inherited metabolic disorder in which the body is unable to properly break down the amino acid leucine. Because the enzyme isovaleryl-CoA dehydrogenase is deficient or absent, toxic byproducts like isovaleric acid build up in the body. If left unmanaged, this accumulation can lead to serious health complications, ranging from acute metabolic crises to developmental delays. At DiseaseMaps.org, we currently support a community of 23 people with Isovaleric acidemia who share their personal experiences, highlighting the importance of early diagnosis through newborn screening.

How are medical codes like ICD-10 used for Isovaleric acidemia?

Medical coding serves as a universal language for healthcare providers and insurers. The ICD-10 code E71.110 is specifically designated for Isovaleric acidemia, ensuring that clinical records, hospitalizations, and specialized diet therapies—such as leucine-restricted formulas—are correctly documented. Using the accurate ICD code is vital for families to secure coverage for the ongoing metabolic monitoring and medical foods required to manage Isovaleric acidemia effectively over a lifetime.

What are the common management strategies for Isovaleric acidemia?

Management of Isovaleric acidemia is highly individualized and focuses on preventing the buildup of toxic metabolites. Because the condition is lifelong, a multidisciplinary approach is required. Key components of managing this metabolic condition include:

• Protein Restriction: A diet strictly limited in leucine, often supplemented with medical formulas to ensure essential amino acid intake.


• Metabolic Monitoring: Regular blood tests to monitor levels of isovalerylglycine and other related metabolites.


• Emergency Protocols: An "emergency letter" provided by a metabolic specialist to be used during illness or surgery to prevent metabolic decompensation.


• L-carnitine Supplementation: Often prescribed to help the body excrete excess isovaleric acid.

Is Isovaleric acidemia a hereditary condition?

Yes, Isovaleric acidemia is an autosomal recessive genetic disorder. This means that an affected individual has inherited two non-working copies of the IVD gene, one from each parent. Parents of a child with Isovaleric acidemia are typically asymptomatic "carriers" who have one working copy and one non-working copy of the gene. Genetic counseling is highly recommended for families to understand the 25% recurrence risk for each future pregnancy and to discuss family planning options.

Next steps

• Consult with a metabolic geneticist or a specialized metabolic dietitian to review your current management plan.


• Ensure your medical team is using the correct ICD-10 code (E71.110) for all insurance and documentation purposes.


• Connect with the 23 community members at DiseaseMaps.org to share experiences and coping strategies for living with a metabolic disorder.


• Keep an updated "emergency protocol" document in your wallet or mobile device at all times.
