2025 ICD-10-CM code C30.0

Malignant neoplasm of nasal cavity. Includes: malignant neoplasm of cartilage of nose, nasal concha, internal nose, septum of nose, and vestibule of nose.

Use additional codes to identify any functional activity associated with the neoplasm (Chapter 4).If the neoplasm overlaps contiguous sites within the nasal cavity, use code C30.8 unless a specific combination code exists. If there are multiple non-contiguous tumors in the same site (e.g., different quadrants of the nose), code each site separately.

Medical necessity for treatment of a malignant neoplasm of the nasal cavity is established by the confirmed diagnosis of malignancy based on histopathological examination.Treatment options, including surgery, chemotherapy, and radiation therapy, are determined based on the stage, location, and type of cancer.

The provider diagnoses the condition based on history, physical examination, and symptoms. Diagnostic tests include X-rays, MRI of head and neck, nasal endoscopy, and nasal mass biopsy. Treatment depends on the stage and location of the neoplasm.If resectable, surgical management is the primary treatment along with chemotherapy and radiotherapy. For advanced neoplasms, chemotherapy and radiotherapy are used to improve the quality of life.

In simple words: Cancer of the nasal cavity. This refers to the uncontrolled growth of harmful cells within the nose.

Malignant neoplasm of nasal cavity. This code encompasses malignancies originating in various parts of the nasal cavity, including the cartilage, nasal concha (turbinates), internal nose, nasal septum, and vestibule.It excludes malignancies of the nasal bone (C41.0), nose NOS (C76.0), olfactory bulb (C72.2-), posterior margin of nasal septum and choana (C11.3), malignant melanoma of skin of nose (C43.31), and other skin malignancies of the nose (C44.301, C44.311, C44.321, C44.391).

Example 1: A patient presents with persistent nosebleeds, nasal obstruction, and facial pain. After a thorough examination and imaging studies, a biopsy confirms a malignant neoplasm of the nasal septum. The diagnosis is coded as C30.0., A patient with a history of occupational exposure to wood dust develops a mass in the nasal cavity. Biopsy reveals a squamous cell carcinoma of the nasal concha. The appropriate ICD-10-CM code is C30.0., An elderly patient experiences a decreased sense of smell and recurrent sinus infections.A nasal endoscopy and subsequent biopsy identify a malignant tumor originating in the vestibule of the nose.This is coded as C30.0.

Documentation should include details of the patient's history, physical examination findings, imaging results (X-ray, MRI, CT), nasal endoscopy findings, and biopsy results confirming the diagnosis and location of the malignancy within the nasal cavity.
