2025 ICD-10-CM code C34.11

Malignant neoplasm of the upper lobe of the right lung or right bronchus.

Use additional codes to identify tobacco use/exposure (Z72.0, Z77.22, P96.81, Z87.891, Z57.31, F17.-). Do not use C34.11 for Kaposi's sarcoma (C46.5-) or malignant carcinoid tumor (C7A.090).

Medical necessity for procedures related to C34.11 should be supported by documentation of signs, symptoms, and diagnostic findings confirming the presence of the malignancy. Treatment should align with established guidelines and be appropriate for the patient's specific condition and stage of cancer.

Clinicians should document patient history, symptoms (cough, wheezing, shortness of breath, difficulty swallowing, chest pain, weakness, weight loss, recurring infections), and conduct physical examinations. Laboratory tests (CBC, blood chemistry, sputum examination, respiratory function tests, biopsy) and imaging (X-ray, CT, MRI, bronchoscopy, mediastinoscopy, thoracoscopy, PET) are crucial for diagnosis and staging. Treatment depends on stage and location and may include surgery, chemotherapy, radiotherapy, radiofrequency ablation, or immunotherapy.

In simple words: Cancer in the upper part of your right lung, affecting either the main airway (bronchus) or the lung tissue.

Malignant neoplasm of the upper lobe, right bronchus or lung. This code represents the presence of a cancerous growth originating in the upper part of the right lung, specifically affecting the right bronchus or the lung tissue itself.

Example 1: A 65-year-old patient with a history of smoking presents with a persistent cough and weight loss. Imaging reveals a mass in the upper lobe of the right lung, confirmed as malignant through biopsy. C34.11 is used for diagnosis coding., A 50-year-old patient undergoes bronchoscopy due to hemoptysis. Biopsy of a lesion in the right upper lobe bronchus confirms malignancy, leading to the use of C34.11., During a routine chest X-ray, a small nodule is discovered in the upper lobe of a patient's right lung. Subsequent CT scans and biopsy confirm the presence of a malignant neoplasm. C34.11 is assigned.

Thorough documentation should include patient demographics, medical history (smoking, exposures), presenting symptoms, physical exam findings, results of laboratory tests (CBC, blood chemistry, sputum analysis, biopsy), imaging reports (X-ray, CT, MRI, PET, bronchoscopy), and treatment plan.
