Nasal polyp (J33)
ICD-10 code J33 and its subcategories classify different types of nasal polyps, which are noncancerous growths in the nasal cavity and sinuses. These codes help specify the exact location and type of nasal polyps for accurate medical documentation and treatment planning.
The code J33.0 covers polyps located specifically within the nasal cavity, including variations such as choanal or nasopharyngeal polyps. This is useful when identifying growths that affect the mucous membrane of various nasal regions. J33.1 refers to polypoid sinus degeneration, often related to sinus inflammation alongside nasal polyps, sometimes noted as sinusitis with nasal polyps. The code J33.8 includes other sinus polyps found in areas like the maxillary, ethmoidal, frontal, or sphenoidal sinuses. When the polyp's location or type is not clearly defined, J33.9 identifies unspecified nasal polyps, often linked with chronic rhinosinusitis or multiple nasal polyps. These codes help medical professionals pinpoint the site and nature of nasal polyps, aiding in diagnosis, treatment decisions, and proper medical billing for conditions involving nasal and sinus growths.
Instructional Notations
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.

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.
Allergic Fungal Sinusitis
Fungal infection in the PARANASAL SINUSES characterized by common allergy respiratory symptoms, recurrent NASAL POLYPS and/or ASTHMA with buildup of allergic MUCIN.
Rhinosinusitis
Obstruction of sinus drainage into the NASAL CAVITY and inflammation of the NASAL MUCOSA in the PARANASAL SINUSES.
