The ICD-10 code for Acute on chronic respiratory failure (ACRF) with hypoxia is J96.21
Step-by-step explanation:
The ICD-10 codes ranging from J00-J99 stands for various respiratory system diseases and disorders. These respiratory failure disease codes are assigned based on their nature (acute, chronic, or unspecified) and the accompanying hypoxic or hypercapnic conditions.
The code J96.20 is the code for unspecified ACRF.
The code J96.21 is the billable and specific code for hypoexemic acute-on-chronic respiratory failure.
ACRF arises due to a sudden insult leading to quick emergent short-term exacerbation of the existing chronic respiratory failure. This results in sudden deterioration of the patient’s condition leading to hypoxemia.
