2025 ICD-10-CM code C11.1
Malignant neoplasm of the posterior wall of the nasopharynx (part of the throat open to the nasal cavity).
Medical necessity is established by the presence of a malignant neoplasm confirmed by biopsy and imaging, along with associated signs and symptoms. Treatment is deemed medically necessary to eradicate the tumor and prevent its spread.
Symptoms include facial pain, bloody sputum, speech difficulty, ear pain/deafness, bloody nasal discharge, congestion, headaches, neck lumps, and enlarged lymph nodes. Diagnosis involves patient history, nose/throat/ear/neck exam, endoscopy, biopsy, blood tests, and EBV testing. Imaging (X-ray, CT, MRI, PET) helps diagnose and stage the cancer. Treatment may include chemotherapy, radiation, surgery, and targeted therapy.
In simple words: Cancer on the back wall of the nasopharynx (the upper part of your throat, behind your nose) that can spread. Main risks are past infection with the Epstein-Barr virus, some gene changes, family history of this cancer, and eating preserved fish or meat.
Malignant neoplasm of the posterior wall of the nasopharynx. This cancerous growth can spread to other tissues. Risk factors include prior Epstein-Barr virus (EBV) infection, genetic mutations, family history, and consuming preserved fish/meat.
Example 1: A 50-year-old male presents with persistent nasal congestion, occasional bloody discharge, and a lump in his neck. After examination, imaging, and biopsy, he is diagnosed with a malignant neoplasm of the posterior nasopharyngeal wall., A patient with a history of EBV infection experiences difficulty speaking and swallowing. A nasopharyngeal examination and biopsy reveal a malignant tumor on the posterior wall., An individual with a family history of nasopharyngeal cancer develops ear pain and hearing loss. A thorough examination, including imaging, leads to a diagnosis of C11.1.
Diagnosis requires documentation of symptoms, physical exam findings, endoscopy/biopsy results, imaging reports, and EBV test results. Treatment documentation should include details of chemotherapy, radiation therapy, surgical procedures, and targeted therapies administered.
