ICD-10 Code J96.20 – Acute and chronic respiratory failure, unspecified whether with hypoxia or hypercapnia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J96.20 – Acute and chronic respiratory failure, unspecified whether with hypoxia or hypercapnia
What it is
J96.20 identifies respiratory failure that is both acute and chronic, but the record does not specify whether hypoxia, hypercapnia, or both are present. Use it when the documentation clearly states this combined diagnosis.
Clinical signs
Patients may show shortness of breath, increased work of breathing, confusion, or need for ventilatory support. Clinical features vary; refer to documentation for whether oxygenation, ventilation, or both are impaired.
When to use this code
Use this code when the provider documents acute and chronic respiratory failure together and does not specify hypoxia or hypercapnia. It is appropriate for inpatient or outpatient records only when the diagnosis is clearly stated. If the note distinguishes the type of failure, code that more specific option instead.
Do not use for
Do not use it for respiratory failure described only as acute or only as chronic. Also avoid it when the chart specifies hypoxia or hypercapnia separately and a more precise code is supported.
Coding tip
Check the provider’s exact wording; the presence or absence of hypoxia or hypercapnia changes code selection.
