Clinical InformationClinical
Hyperuricemia
excessive uric acid or urate in blood as defined by its solubility in plasma at 37 degrees c; greater than 0.42mmol per liter (7.0mg/dl) in men or 0.36mmol per liter (6.0mg/dl) in women. this condition is caused by overproduction of uric acid or impaired renal clearance. hyperuricemia can be acquired, drug-induced or genetically determined (lesch-nyhan syndrome). it is associated with hypertension and gout.Lesch-Nyhan Syndrome
an inherited disorder transmitted as a sex-linked trait and caused by a deficiency of an enzyme of purine metabolism; hypoxanthine phosphoribosyltransferase. affected individuals are normal in the first year of life and then develop psychomotor retardation, extrapyramidal movement disorders, progressive spasticity, and seizures. self-destructive behaviors such as biting of fingers and lips are seen frequently. intellectual impairment may also occur but is typically not severe. elevation of uric acid in the serum leads to the development of renal calculi and gouty arthritis. (menkes, textbook of child neurology, 5th ed, pp127)Hypoxanthine Phosphoribosyltransferase
an enzyme that catalyzes the conversion of 5-phosphoribosyl-1-pyrophosphate and hypoxanthine, guanine, or mercaptopurine to the corresponding 5'-mononucleotides and pyrophosphate. the enzyme is important in purine biosynthesis as well as central nervous system functions. complete lack of enzyme activity is associated with the lesch-nyhan syndrome, while partial deficiency results in overproduction of uric acid. ec 2.4.2.8.

Metabolism is the process your body uses to get or make energy from the food you eat. Food is made up of proteins, carbohydrates, and fats. Chemicals in your digestive system break the food parts down into sugars and acids, your body's fuel.

Questions About E79.0Overview
Is E79.0 (Disorders of purine and pyrimidine metabolism) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report hyperuricemia without signs of inflammatory arthritis and tophaceous disease on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does E79.0 group to?
When hyperuricemia without signs of inflammatory arthritis and tophaceous disease is the principal diagnosis on an inpatient stay, it groups to MS-DRG 947, 948, with relative weights from 0.8005 to 1.2694 depending on complications. Higher weights mean higher Medicare reimbursement.
What is the ICD-9 equivalent of E79.0?
Under the General Equivalence Mappings, hyperuricemia without signs of inflammatory arthritis and tophaceous disease converts to ICD-9-CM 790.6 (abn blood chemistry NEC). The mapping is approximate, so confirm the match fits the documentation.
Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
