ICD-10 Code E79.89 – Other specified disorders of purine and pyrimidine metabolism (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E79.89 – Other specified disorders of purine and pyrimidine metabolism
What it is
This code identifies a documented disorder of purine or pyrimidine metabolism that does not fit a more specific ICD-10-CM category. Use it when the provider names a distinct metabolic condition, but no exact code is available.
Clinical signs
Clinical features vary; refer to documentation. Findings may reflect abnormal purine or pyrimidine handling, but you should code only when the record supports a specific metabolic disorder.
When to use this code
Use E79.89 when the clinician documents an “other specified” purine or pyrimidine metabolic disorder and the chart does not support a more specific code. It may apply when the condition is named in the assessment, problem list, or discharge summary. If the diagnosis is unclear, check documentation.
Do not use for
Do not use this code for gout, hyperuricemia, or other separately coded metabolic disorders. If the record only mentions abnormal labs or a suspected condition without a documented diagnosis, do not assign this code.
Coding tip
Match the provider’s exact wording and confirm that no more specific purine or pyrimidine code applies before selecting E79.89.
