ICD-10 Code I95.0 – Idiopathic hypotension (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I95.0 – Idiopathic hypotension
What it is
Use this code for low blood pressure that is not explained by another condition. “Idiopathic” means the cause is unknown or not documented.
Clinical signs
Clinical features vary; refer to documentation. Patients may have persistent low blood pressure with dizziness, lightheadedness, weakness, or fainting, but the record should support a diagnosis of hypotension without another identified cause.
When to use this code
Assign I95.0 when the provider documents idiopathic hypotension, primary hypotension, or hypotension of unknown cause. Use it when the chart shows low blood pressure as the diagnosed condition and no secondary cause is stated.
Do not infer this code from a single low reading alone. Check documentation if hypotension is only mentioned as a symptom, a transient finding, or part of another disorder.
Do not use for
Do not use this code for hypotension clearly linked to dehydration, shock, medication effect, or another underlying disease. Check documentation if the provider identifies a different cause.
Coding tip
Code the documented diagnosis, not the blood pressure number; if the cause is unclear, confirm that the provider specifically identifies idiopathic hypotension.
