ICD-10 Code G93.41 – Metabolic encephalopathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G93.41 – Metabolic encephalopathy
What it is
G93.41 identifies encephalopathy caused by a metabolic disturbance, meaning brain dysfunction due to an underlying systemic problem rather than a primary brain disease.
Clinical signs
Clinical features vary; refer to documentation. Common findings include altered mental status, confusion, reduced alertness, and impaired attention or cognition.
When to use this code
Use G93.41 when the provider documents metabolic encephalopathy and links the mental status change to a metabolic cause. It is appropriate when the record clearly supports encephalopathy from conditions such as electrolyte imbalance, renal failure, or other metabolic derangements. Check documentation if the cause is not stated.
Do not use for
Do not use this code for delirium, coma, or nonspecific confusion without documentation of metabolic encephalopathy. Avoid it when the encephalopathy is due to another specified cause.
Coding tip
Code the underlying metabolic condition first when sequencing rules require it, and report G93.41 only when the provider explicitly documents metabolic encephalopathy.
