ICD-10 Code I95.9 – Hypotension, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I95.9 – Hypotension, unspecified
What it is
I95.9 identifies hypotension when the record does not specify a cause or subtype. Use it for documented low blood pressure without further detail.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings may include dizziness, lightheadedness, weakness, or syncope, but you should code only when hypotension is clearly documented.
When to use this code
Use I95.9 when the clinician documents hypotension and does not identify orthostatic, drug-induced, or another specific form. It is also appropriate when the chart simply states “hypotension” without additional clarification.
If the record links low blood pressure to another condition, follow the documented cause and sequence coding as directed. Check documentation when the type, cause, or acuity is unclear.
Do not use for
Do not use I95.9 when a more specific hypotension code is documented, such as orthostatic or drug-related hypotension. Do not assign it for transient symptoms without a documented diagnosis.
Coding tip
Query the provider when the note says only “low BP” but the type or cause is missing.
