ICD-10: J05.0

The diagnosis of Acute obstructive laryngitis, commonly known as croup, is primarily clinical and is characterized by several key symptoms. Here are the criteria used for diagnosis:

• Classic Symptoms: The most notable presentation includes an acute onset of a "seal-like" barking cough, which is a hallmark of croup. Additionally, patients may exhibit inspiratory stridor (a high-pitched wheezing sound), hoarseness, and chest wall retractions during breathing [5][9].

• Age Group: Croup typically affects young children, particularly those between 6 months and 3 years of age, although it can occur in older children as well [5].

• Exclusion of Other Conditions: The diagnosis may also involve ruling out other potential causes of similar symptoms, such as foreign body aspiration or other upper airway infections [5].

• Severity Assessment: The severity of the condition can be assessed based on the presence and intensity of stridor, the degree of respiratory distress, and the overall clinical appearance of the child [5].

• ICD-10 Coding: For coding purposes, the ICD-10 code J05.0 is specifically designated for acute obstructive laryngitis (croup), and it is important to note that this code is valid for the current fiscal year for billing and insurance purposes [15].

These criteria help healthcare providers accurately diagnose and manage croup, ensuring appropriate treatment and care for affected children.
