About J34.83

J34.83 is the ICD-10-CM diagnosis code for odontogenic sinusitis. It belongs to category J34 (other and unspecified disorders of nose and nasal sinuses), block J30-J39 (other diseases of upper respiratory tract) and chapter 10 (diseases of the respiratory system). It is a header code, so it can't be reported by itself; one of its 5 subcodes must be used instead.

Within J34.8 (other specified disorders of nose and nasal sinuses), J34.83 is specifically for odontogenic sinusitis. Related codes cover nasal mucositis (ulcerative) (J34.81), nasal valve collapse (J34.82) and other specified disorders of nose and nasal sinuses (J34.89).

To report this condition, pick the subcode that matches the documentation: J34.830 (maxillary sinus), J34.831 (ethmoid sinus), J34.832 (frontal sinus), J34.833 (sphenoid sinus) and J34.839 (unspecified).

It was added in FY2027, effective October 1, 2026.
