Acute laryngitis and tracheitis (J04)

Browse all the diagnosis codes used for acute laryngitis and tracheitis (j04). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range. This format makes it simple to browse diagnosis codes in this chapter or section and find what you're looking for. We've also added green checkmark icons to label billable codes, and red warning icons for non-billable ones. This makes it easy to identify which codes can be billed.

Clinical Information

Laryngitis - Inflammation of the LARYNGEAL MUCOSA, including the VOCAL CORDS. Laryngitis is characterized by irritation, edema, and reduced pliability of the mucosa leading to VOICE DISORDERS such as APHONIA and HOARSENESS.

Supraglottitis - Inflammation of the EPIGLOTTIS and supraglottic structures including the PHARYNX; UVULA; base of tongue; and aryepiglottic folds. It is usually caused by HAEMOPHILUS INFLUENZAE in children but often by different organisms in adults.

Tracheitis - INFLAMMATION of the TRACHEA that is usually associated with RESPIRATORY TRACT INFECTIONS.

Instructional Notations

Code Also

A "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.

• influenza, if present, such as:
• influenza due to identified novel influenza A virus with other respiratory manifestations J09.X2
• influenza due to other identified influenza virus with other respiratory manifestations J10.1
• influenza due to unidentified influenza virus with other respiratory manifestations J11.1

Use Additional Code

The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.

• code B95 B97

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

• acute obstructive laryngitis [croup] and epiglottitis J05

Type 2 Excludes

A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

• laryngismus stridulus J38.5
