Respiratory failure, unspecified with hypoxia

This code signifies a patient experiencing respiratory failure of an unknown or unspecified etiology, characterized by insufficient oxygenation of the blood (hypoxia). It indicates the lungs are unable to adequately exchange gases, leading to low blood oxygen levels without a specified underlying cause for the respiratory compromise.

Use this code when documentation clearly states "respiratory failure with hypoxia" but does not specify whether it is acute, chronic, or acute on chronic, nor does it identify the underlying cause. This is appropriate for initial presentations where the specific type or etiology of respiratory failure is still under investigation or not yet determined.

• Do not use this code if the documentation specifies acute, chronic, or acute on chronic respiratory failure; instead, select the more specific J96.0x or J96.2x codes.
• Always sequence the underlying condition causing the respiratory failure (if known) before this code.
• Query the provider for clarification on the type and etiology of respiratory failure whenever possible to allow for more specific coding.
