Chronic respiratory failure, unsp w hypoxia or hypercapnia

This code signifies a long-standing impairment of the respiratory system's ability to adequately exchange oxygen and carbon dioxide, where the specific nature of the gas exchange abnormality (low oxygen or high carbon dioxide) is not documented. It indicates a persistent, rather than acute, failure of the lungs to perform their primary function.

This code is appropriate when a patient has a documented history or current diagnosis of chronic respiratory failure, but the medical record does not specify if it is primarily hypoxic (low oxygen) or hypercapnic (high carbon dioxide). It is often used when the physician's documentation simply states "chronic respiratory failure" without further detail.

• Only use this code when the documentation explicitly lacks specificity regarding hypoxia or hypercapnia.
• Always query the provider for clarification if "chronic respiratory failure" is documented without further detail, to determine if J96.11 (with hypoxia) or J96.12 (with hypercapnia) can be assigned.
• This code is often a principal diagnosis if it's the reason for admission or a significant comorbidity affecting treatment.
