What is ICD-10 for hyperammonemia?
E72. 29 is a billable diagnosis code used to specify a medical diagnosis of other disorders of urea cycle metabolism. In a healthy adult, the total soluble ammonia level is only mcg with 5 l of blood.
What do you mean by hyperammonemia?
Hyperammonemia is a metabolic condition characterized by elevated levels of ammonia in the blood.Sep 29, 2021
What are the symptoms of hyperammonemia?
Symptoms include irritability, headache, vomiting, ataxia, and gait abnormalities in the milder cases. Seizures, encephalopathy, coma, and even death can occur in cases with ammonia levels greater than 200 micromol/L.
What is the treatment for hyperammonemia?
Rifaximin has become the most effective antibiotic of choice in the treatment of hyperammonemia because of its safety, efficacy, and tolerability [62]. Rifaximin is a nonsystemic, GI site-specific antibiotic as a result of the addition of a nonabsorbable pyridoimidazole ring.Jan 28, 2018
How is hyperammonemia diagnosis?
The most important diagnostic test for the diagnosis of hyperammonemia is measuring plasma ammonia. Various biomarkers are used for the differential diagnosis of hyperammonia. They include plasma and urine amino acid profiles, urine organic acid profiles, and plasma acylcarnitine profiles.
What are the types of hyperammonemia?
Specific types
Online Mendelian Inheritance in Man (OMIM): 606762 - hyperinsulinism-hyperammonemia syndrome (glutamate dehydrogenase 1) Online Mendelian Inheritance in Man (OMIM): 238970 - hyperornithinemia-hyperammonemia-homocitrullinuria.

What is the cause of hyperammonemia?
Hyperammonemia is due to defect in detoxification or overproduction of ammonia. Defects in the urea cycle lead to the most severe hyperammonemia. Other causes of hyperammonemia include various metabolic defects such as certain organic acidurias, fatty acid oxidation defects, drugs and liver disease.
Is hyperammonemia genetic?
In the genetic forms of hyperammonemia, men and women are affected equally because almost all types are autosomal recessive traits. The only exception to equal sex distribution is X-linked ornithine transcarbamylase (OTC) deficiency, the most common of the urea cycle disorders.Sep 20, 2018
What causes Type 2 hyperammonemia?
Hyperammonemia, caused by mutation in ornithine transcarbamylase gene, is often considered as a reason of coma by pediatricians but skipped by internist, although it is the third reason of hepatic coma in adults.
What happens during hyperammonemia?
In most hyperammonemic episodes, patients may present with a loss of appetite, vomiting, lethargy, and behavior abnormalities associated with hallucinations, sleep disorders, ataxia, and even seizures. These episodes are usually related to periods of high protein intake, systemic infection, or catabolic stress.Mar 13, 2014
How is hyperammonemia managed in the clinic?
The management of hyperammonemia includes 1) identification of precipitating factors and cerebral edema presence, 2) a decrease in ammonia production by reducing protein intake and reversing catabolism, and 3) ammonia removal with pharmacologic treatment and, in the most severe cases, with extracorporeal therapies.Sep 12, 2018
How does hyperammonemia affect TCA cycle?
Elevated ammonia concentrations also inhibit decarboxylation of alpha-ketoglutarate in the TCA cycle. This effect occurs in both neurons and astrocytes, is unrelated to MAS activity and seen after chronic treatment with ammonia even in the absence of elevated ammonia concentrations.
