ICD-10 Code E83.50 – Unspecified disorder of calcium metabolism (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E83.50 – Unspecified disorder of calcium metabolism
What it is
E83.50 identifies a disorder of calcium metabolism when the record does not specify the exact type. Use it when the chart shows an abnormal calcium-handling condition, but the cause or subtype is not documented.
Clinical signs
Clinical features vary; refer to documentation. Findings may include symptoms or assessment notes consistent with disturbed calcium balance, but the record must not name a more specific metabolic disorder.
When to use this code
Use this code when the provider documents a calcium metabolism disorder without further detail, or when the available note is too nonspecific for a more precise code. It is appropriate for unresolved or unspecified calcium-related metabolic problems in the assessment.
If the documentation later identifies a clearer diagnosis, you should code the more specific condition instead. Check documentation for whether the issue is congenital, endocrine, renal, or another defined disorder.
Do not use for
Do not use E83.50 when the chart names a specific calcium disorder, such as hypocalcemia or hypercalcemia. Also avoid it if the abnormality is only a lab finding without a documented disorder.
Coding tip
Use the unspecified code only when the provider’s documentation truly lacks detail; query for specificity whenever possible.
