ICD10 code of Propionic Acidemia and ICD9 code

Propionic Acidemia is classified under the ICD-10 code E71.121 (Propionic acidemia) and the ICD-9 code 270.3 (Disturbances of branched-chain amino-acid metabolism). These medical billing codes are essential for healthcare providers, insurance companies, and researchers to track and manage the clinical care of patients with this rare metabolic disorder.

What is the clinical significance of Propionic Acidemia?

Propionic Acidemia is a rare, life-threatening metabolic disorder characterized by the body's inability to properly break down certain proteins and fats. Specifically, individuals with Propionic Acidemia lack the functional enzyme propionyl-CoA carboxylase, leading to the accumulation of toxic organic acids in the blood and tissues. This biochemical imbalance can lead to severe metabolic crises, often manifesting as lethargy, vomiting, and developmental delays. At DiseaseMaps.org, 17 people with Propionic Acidemia have joined our community to share their experiences and navigate the complexities of managing this condition alongside their medical teams.

How are the ICD codes for Propionic Acidemia used in practice?

The use of standardized coding, such as ICD-10 E71.121, ensures that patients with Propionic Acidemia receive accurate billing, appropriate insurance coverage for specialized formulas and medications, and proper documentation in their electronic health records. These codes allow clinical researchers to identify patient cohorts for longitudinal studies and clinical trials. Because Propionic Acidemia is a complex, multisystem disease, accurate coding helps medical specialists—including metabolic geneticists, neurologists, and dietitians—coordinate care effectively across different departments.

What are the key diagnostic and management factors for Propionic Acidemia?

Diagnosis is typically confirmed through newborn screening or follow-up blood and urine testing that identifies elevated levels of propionylcarnitine and other metabolites. Management of Propionic Acidemia requires a lifelong, highly specialized approach to prevent metabolic decompensation. Common management strategies include:

• Strict dietary protein restriction: Limiting intake of amino acids isoleucine, valine, methionine, and threonine.


• Metabolic formula supplementation: Providing essential nutrients without the problematic amino acids.


• Carnitine supplementation: Helping the body excrete toxic metabolites.


• Emergency protocols: Having a pre-planned "sick day" regimen to manage metabolic crisis during illness or stress.


• Frequent monitoring: Regular laboratory testing of plasma amino acids and acylcarnitine profiles.

Is Propionic Acidemia hereditary?

Yes, Propionic Acidemia is an autosomal recessive genetic disorder caused by mutations in the PCCA or PCCB genes. This means that both parents must be carriers of a mutation to pass the condition to their child, with each pregnancy carrying a 25% risk of the child inheriting the disorder. Genetic counseling is strongly recommended for families affected by Propionic Acidemia to understand recurrence risks and available reproductive options.
