2014 ICD-9-CM Diagnosis Code 270.6
Disorders of urea cycle metabolism
- Short description: Dis urea cycle metabol.
- ICD-9-CM 270.6 will be replaced by an equivalent ICD-10-CM code (or codes) when the United States transitions from ICD-9-CM to ICD-10-CM on October 1, 2015.
- ICD-9-CM 270.6 is a billable medical code that can be used to specify a diagnosis on a reimbursement claim.

- Hyperornithinemia-hyperammonemia-homocitrullinuria syndrome
- N-acetylglutamate synthetase deficiency
- Ornithine carbamoyltransferase deficiency
- Ornithine metabolism disorder
- Ornithine transcarbamylase deficiency
- Urea cycle metabolism disorder
- A genetic inborn error of metabolism characterized by the deficiency of one of the enzymes necessary for the urea cycle. It results in accumulation of ammonia in the body.
- Autosomal recessive aminoacidopathy characterized by marked elevation in plasma and urine levels of citrulline, with hyperammonemia and sometimes secondary oroticaciduria; clinical findings include mental retardation and neurologic abnormalities.
- Excess of ornithine in the plasma, such as occurs in the genetic disorders gyrate atrophy of choroid and retina and hyperornithinemia-hyperamonemia-homocitrullinuria syndrome.
- Inherited errors in the metabolic reactions occurring in the liver that convert ammonia to urea, resulting from inborn genetic mutations.
- Rare congenital metabolism disorders of the urea cycle. The disorders are due to mutations that result in complete (neonatal onset) or partial (childhood or adult onset) inactivity of an enzyme, involved in the urea cycle. Neonatal onset results in clinical features that include irritability, vomiting, lethargy, seizures, neonatal hypotonia; respiratory alkalosis; hyperammonemia; coma, and death. Survivors of the neonatal onset and childhood/adult onset disorders share common risks for encephalopathies, metabolic, inborn; and respiratory alkalosis due to hyperammonemia.
- Argininosuccinic aciduria
- Disorders of metabolism of ornithine, citrulline, argininosuccinic acid, arginine, and ammonia
