J31.1
ICD-10-CMThis code represents persistent inflammation of the nasopharynx, the area behind the nose and above the soft palate. It is characterized by chronic symptoms such as postnasal drip, nasal obstruction, and throat irritation, without an acute infectious process.
Use this code when documentation clearly indicates a chronic inflammatory condition of the nasopharynx. This typically applies to patients experiencing long-standing or recurrent symptoms that are not attributed to an acute infection. Supporting documentation should specify the chronicity of the condition.
