ICD-10 Code E87.2 – Acidosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E87.2 – Acidosis
What it is
Acidosis is a condition where the body’s blood or tissues become too acidic. Use this code for documented acidosis when the record does not specify a more precise cause or type.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include rapid breathing, confusion, fatigue, or other signs of an acid-base imbalance, but the diagnosis should be supported by the provider’s assessment.
When to use this code
Use E87.2 when the provider documents acidosis without naming a specific underlying disorder such as diabetic, lactic, or respiratory acidosis. It may also fit cases where the chart notes an acid-base disturbance and the type is not further defined.
Code the documented condition, not the lab result alone. If the record identifies a cause or a more specific acid-base disorder, choose that diagnosis instead.
Do not use for
Do not use this code for a more specific acidosis diagnosis when one is documented. Do not assign it for isolated abnormal laboratory values without a provider diagnosis; check documentation.
Coding tip
Look for the exact type and cause of acidosis in the note before defaulting to E87.2.
