ICD-10 Code J96.9 – Respiratory failure, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J96.9 – Respiratory failure, unspecified
What it is
J96.9 identifies respiratory failure when the record does not specify whether it is acute, chronic, or acute on chronic. Use this code when documentation confirms respiratory failure but gives no further detail.
Clinical signs
Clinical features vary; refer to documentation. Commonly, patients may have labored breathing, hypoxemia, hypercapnia, or need for ventilatory support, but the exact type and severity must be documented.
When to use this code
Use J96.9 when the provider documents respiratory failure without specifying acute or chronic status, or when the note only states “respiratory failure” and no more detail is available. It may also be appropriate when coding from a summary that does not clarify the type. Check documentation for laterality, acuity, and any linked conditions before assigning a more specific code.
Do not use for
Do not use this code if the record clearly states acute respiratory failure, chronic respiratory failure, or acute on chronic respiratory failure. Do not use it when respiratory distress or insufficiency is documented without confirmed failure.
Coding tip
If the type of respiratory failure is unclear, query for acuity and chronicity before defaulting to J96.9.
