Causes and Risk Factors for Acute Laryngitis or Tracheitis

Acute laryngitis or tracheitis is primarily caused by upper respiratory tract viral infections. Voice abuse can also be a contributing factor to laryngitis. In some cases, particularly with tracheitis, bacterial infections can follow an initial viral illness, with common culprits including Staphylococcus aureus and streptococci.

Synonyms and Alternative Terms for Acute Laryngitis or Tracheitis

This condition is officially classified under the ICD-11 code CA05. It encompasses several related terms, including acute laryngitis (CA05.0), acute tracheitis (CA05.1), and acute laryngotracheitis (CA05.2). Other clinical synonyms may include laryngotracheitis NOS, tracheitis with laryngitis, and historically, terms like Haemophilus influenzae laryngotracheitis or Streptococcal laryngotracheitis when specific causative agents were identified.

Clinical Overview of Acute Laryngitis or Tracheitis

Acute laryngitis or tracheitis refers to the sudden onset of inflammation affecting the larynx (voice box) and/or the trachea (windpipe). This inflammation is characterised by local findings such as redness (erythema) and swelling (oedema) of the mucosal lining within these airways. It falls under the broader category of upper respiratory tract disorders in the ICD-11 classification.

How Acute Laryngitis or Tracheitis is Diagnosed

Diagnosis of acute laryngitis or tracheitis is typically based on the presence of characteristic clinical signs and symptoms, alongside visual confirmation of inflammation, such as erythema and oedema of the laryngeal and tracheal mucosa. Medical professionals assess the patient's presentation and may use diagnostic tools to visualise the affected areas.

Common Symptoms and Presentation of Acute Laryngitis or Tracheitis

Symptoms can vary depending on whether the larynx, trachea, or both are primarily affected. Laryngitis often presents with hoarseness, a sore throat, and potential voice loss. Tracheitis may manifest as a barking or croup-like cough, loud squeaking noises during breathing, a scratchy throat sensation, high fever, and the production of significant amounts of pus-filled secretions. When both are involved (laryngotracheitis), a combination of these symptoms may be observed.

Treatment and Management Considerations for Acute Laryngitis or Tracheitis

Management strategies focus on alleviating symptoms and addressing the underlying cause. For viral infections, which are common, antibiotics are generally not indicated. Supportive care measures include resting the voice and ensuring adequate hydration. Specific treatments may be tailored based on the severity and the identified cause, distinguishing between laryngitis and tracheitis.

Documentation and Coding Considerations for Acute Laryngitis or Tracheitis

The ICD-11 code CA05 is used for 'Acute laryngitis or tracheitis'. This code serves as a primary classification for these conditions. It is important to note that specific sub-codes exist for acute laryngitis (CA05.0), acute tracheitis (CA05.1), and acute laryngotracheitis (CA05.2), allowing for more precise documentation. Conditions such as laryngismus (stridulus) and acute obstructive laryngitis or epiglottitis (CA06) are excluded from this code.

Frequently asked questions

What is the ICD-11 classification meaning of CA05?
CA05 in ICD-11 denotes Acute laryngitis or tracheitis, referring to the acute inflammation of the larynx, the trachea, or both.
What are the specific ICD-11 codes within the CA05 category for Acute laryngitis or tracheitis?
The CA05 category includes specific codes for Acute laryngitis (CA05.0), Acute tracheitis (CA05.1), and Acute laryngotracheitis (CA05.2).
How is the ICD-11 code CA05 used in relation to its sub-codes?
The general code CA05 is used when the specific condition of acute laryngitis, acute tracheitis, or acute laryngotracheitis is not precisely documented. The more specific codes CA05.0, CA05.1, or CA05.2 should be used when the documentation clearly indicates acute laryngitis, acute tracheitis, or acute laryngotracheitis, respectively.
What anatomical structures are involved in the ICD-11 classification CA05?
ICD-11 code CA05 pertains to acute inflammation affecting the larynx, the trachea, or both the larynx and trachea.
