ICD-10 Code E83.82 – Disorders of pyrophosphate metabolism (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E83.82 – Disorders of pyrophosphate metabolism
What it is
E83.82 identifies disorders involving abnormal pyrophosphate handling in the body. Use it for documented pyrophosphate metabolism problems, including conditions linked to calcium pyrophosphate deposition when the record supports that diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings may include joint pain, swelling, stiffness, or recurrent inflammatory episodes when pyrophosphate crystal disease is present.
When to use this code
Use this code when the provider documents a disorder of pyrophosphate metabolism, pyrophosphate deposition, or a related metabolic abnormality. It may also apply when the assessment specifically names calcium pyrophosphate crystal disease and no more specific code is assigned. Check documentation if the chart only mentions joint symptoms without a confirmed diagnosis.
Do not use for
Do not use this code for nonspecific arthralgia, osteoarthritis, or gout unless pyrophosphate metabolism disorder is documented. If the note describes a different crystal arthropathy or metabolic disorder, code that condition instead.
Coding tip
Look for explicit provider wording such as “pyrophosphate deposition” or “disorders of pyrophosphate metabolism” before assigning E83.82.
