E79.8Other disorders of purine and pyrimidine metabolism

E79.8 is the ICD-10-CM diagnosis code for other disorders of purine and pyrimidine metabolism. 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 a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

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

To report this condition, pick the subcode that matches the documentation: E79.81 (syndrome), E79.82 (xanthinuria) and E79.89 (metabolism).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2024 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 277.2 (other disorders of purine and pyrimidine metabolism).
