E79.0Hyperuricemia without signs of inflammatory arthritis and tophaceous disease

E79.0 is the ICD-10-CM diagnosis code for Hyperuricemia without signs of inflammatory arthritis and tophaceous disease. It belongs to category E79 (disorders of purine and pyrimidine metabolism), block E70-E88 (metabolic disorders) and chapter 4 (endocrine, nutritional and metabolic diseases). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within E79, choose E79.0 (Hyperuricemia without signs of inflammatory arthritis and tophaceous disease) only when documentation doesn't support a more specific option: Lesch-Nyhan syndrome (E79.1), Myoadenylate deaminase deficiency (E79.2), other disorders of purine and pyrimidine metabolism (E79.8) and disorder of purine and pyrimidine metabolism, unspecified (E79.9).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 947 (Signs and Symptoms with MCC, relative weight 1.261) and DRG 948 (Signs and Symptoms without MCC, relative weight 0.7835), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 790.6 (other abnormal blood chemistry).
