International Classification of Diseases

Last updated: 3/24/2026

What is a ICD-10 Code?

ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.

Detailed Description

This code indicates that a patient has hypotension, which means their blood pressure is lower than normal levels. The 'unspecified' designation means that the specific type or underlying cause of the low blood pressure has not been identified or documented. Normal blood pressure is typically around 120/80 mmHg, and hypotension generally refers to readings significantly below this range, though the exact threshold can vary based on individual circumstances.

Additional Information

This is a symptom-based diagnosis that requires further evaluation to determine the underlying cause. Treatment depends on identifying and addressing the root cause of the hypotension.
