Other and unspecified disorders of nose and nasal sinuses (J34)
ICD-10 code section J34 covers a variety of other and unspecified disorders of the nose and nasal sinuses. This group of codes is used to document specific nasal conditions, including abscesses, cysts, structural deformities, and inflammatory disorders that are not classified elsewhere.
The codes range from J34.0 for conditions like nasal abscesses, boils, and cellulitis (also known as abscess of nasal septum or furuncle of the nasal cavity), to J34.1 for nasal and sinus cysts or mucoceles (including cysts of ethmoid or maxillary sinuses). Structural problems like J34.2 for deviated nasal septum (commonly called nasal deviation) and J34.3 for hypertrophy of nasal turbinates are included. Disorders of the nasal valves, such as internal and external nasal valve collapse, have specific codes like J34.82 and J34.821. J34.89 captures other specified disorders, like nasal obstruction, silent sinus syndrome, or nasal septal perforation, while J34.9 covers unspecified nasal or sinus diseases, providing a coding option for more general nasal complaints. This section supports precise coding for a wide range of nasal conditions important for clinical documentation and insurance claims.

Instructional Notations
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.

Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Mouth Breathing
Abnormal breathing through the mouth, usually associated with obstructive disorders of the nasal passages.
Nasal Cavity
The proximal portion of the respiratory passages on either side of the NASAL SEPTUM. Nasal cavities, extending from the nares to the NASOPHARYNX, are lined with ciliated NASAL MUCOSA.
Nasal Obstruction
Any hindrance to the passage of air into and out of the nose. The obstruction may be unilateral or bilateral, and may involve any part of the NASAL CAVITY.
Oral Fistula
An abnormal passage within the mouth communicating between two or more anatomical structures.
