Nasal mucositis (ulcerative)

This code represents inflammation and ulceration of the nasal mucous membranes. It signifies a breakdown of the mucosal lining within the nasal cavity, often presenting with pain, bleeding, and crusting. This condition can be a side effect of certain medical treatments or other underlying causes.

Use this code when documentation explicitly states "nasal mucositis" or "ulcerative nasal mucositis." This is frequently seen in patients undergoing chemotherapy or radiation therapy to the head and neck region, or those with chronic nasal irritation. The physician's notes should clearly indicate the location as nasal.

• Differentiate carefully from other mucositis sites; verify the documentation specifies "nasal."
• Do not use for mucositis of the oral cavity (K12.3-), gastrointestinal tract (K92.81), or vagina/vulva (N76.81).
• Consider an additional code for the underlying cause, such as an adverse effect of a drug, if applicable.
