Answer: The code you’ll want to choose for this patient is J04.0 (Acute laryngitis). “Subglottic laryngitis [acute]” is in the list of alternate terms for J04.0.

Here’s a bit more about the other codes in J04.-:

J040.0 (Acute laryngitis): Acute laryngitis is a condition characterized by inflammation of the larynx. It is usually caused by a viral infection, such as the common cold or flu. Alternate terms for this condition are:

  • Edematous laryngitis (acute)
  • Laryngitis (acute) NOS
  • Subglottic laryngitis (acute)
  • Suppurative laryngitis (acute)
  • Ulcerative laryngitis (acute)

J04.10 (Acute tracheitis without obstruction) and J04.11 (Acute tracheitis with obstruction): Acute tracheitis without obstruction refers to inflammation of the trachea (windpipe) that occurs without any blockage or narrowing of the airway. Acute tracheitis with obstruction has the same symptoms as J04.10, but there is a blockage or narrowing of the airway accompanying the tracheitis. Alternate terms for J04.10 and J04.11 are:

  • Acute viral tracheitis
  • Catarrhal tracheitis (acute)
  • Tracheitis (acute) NOS

J04.2 (Acute laryngotracheitis): Acute laryngotracheitis, also known as croup, is an inflammation of the larynx (voice box) and trachea (windpipe). It primarily affects young children and is usually caused by a viral infection, most commonly the parainfluenza virus. Alternate terms for J04.2 are laryngotracheitis NOS and tracheitis (acute) with laryngitis (acute)

J04.30 (Supraglottitis, unspecified, without obstruction) and J04.31 (Supraglottitis, unspecified, with obstruction): Supraglottitis without obstruction refers to inflammation of the supraglottic area, which is the upper part of the larynx, without any blockage or narrowing of the airway. J04.31 refers to an inflammation of the supraglottic area with blockage or narrowing.
