ICD-10-CM Code C34.90
Malignant neoplasm of unspecified part of unspecified bronchus or lung
Billable CodeBillable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
C34.90 is a billable ICD code used to specify a diagnosis of malignant neoplasm of unspecified part of unspecified bronchus or lung. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
The ICD code C34 is used to code Large-cell lung carcinoma with rhabdoid phenotype
Large cell lung carcinoma with rhabdoid phenotype (LCLC-RP) is a rare histological form of lung cancer, currently classified as a variant of large cell lung carcinoma (LCLC). In order for a LCLC to be subclassified as the rhabdoid phenotype variant, at least 10% of the malignant tumor cells must contain distinctive structures composed of tangled intermediate filaments that displace the cell nucleus outward toward the cell membrane. The whorled eosinophilic inclusions in LCLC-RP cells give it a microscopic resemblance to malignant cells found in rhabdomyosarcoma (RMS), a rare neoplasm arising from transformed skeletal muscle. Despite their microscopic similarities, LCLC-RP is not associated with rhabdomyosarcoma.
