Specific code icon 2015 ICD-10-CM Diagnosis Code C34.90

Malignant neoplasm of unspecified part of unspecified bronchus or lung

    2015 Billable Code

  • C34.90 is a billable ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
  • On October 1, 2015 ICD-10-CM will replace ICD-9-CM in the United States, therefore, C34.90 - and all other ICD-10-CM codes - should only be used for training or planning purposes until then.
  • This is the American ICD-10-CM version of C34.90. Other international ICD-10 versions may differ.

Clinical Information
  • A carcinoma originating in the lung. Lung carcinomas usually arise from the epithelium that lines the bronchial tree (bronchogenic carcinomas), and are classified as small cell or non-small cell carcinomas. Non-small cell lung carcinomas are usually adenocarcinomas, squamous cell carcinomas, or large cell carcinomas. Metastatic carcinomas to the lung are also common, and can be difficult to distinguish from primary tumors.
  • Cancer that forms in tissues of the lung, usually in the cells lining air passages. The two main types are small cell lung cancer and non-small cell lung cancer. These types are diagnosed based on how the cells look under a microscope.
