ICD-10 Code E79.8 – Other disorders of purine and pyrimidine metabolism (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E79.8 – Other disorders of purine and pyrimidine metabolism
What it is
E79.8 identifies a disorder affecting purine or pyrimidine metabolism that does not fit a more specific ICD-10 code. Use it for documented metabolic abnormalities involving these pathways when the exact condition is not named elsewhere.
Clinical signs
Clinical features vary; refer to documentation. Patients may have findings related to abnormal purine or pyrimidine handling, but the code itself does not define a single symptom pattern or laboratory profile.
When to use this code
Use E79.8 when the provider documents an unspecified or other disorder of purine or pyrimidine metabolism and no more specific code is available. It may also apply when the record names a related metabolic condition without enough detail for a narrower code. Check documentation for the exact diagnosis.
Do not use for
Do not use this code for gout, hyperuricemia, or other clearly defined metabolic disorders that have their own ICD-10 codes. If the chart supports a more specific purine or pyrimidine diagnosis, code that instead.
Coding tip
Before assigning E79.8, look for the exact metabolic disorder name in the assessment and problem list.
