212.9
ICD-9-CMThis code signifies the presence of a non-cancerous growth within the respiratory system or other organs located inside the chest cavity, where the precise anatomical origin of the tumor has not been identified. It indicates a benign mass without further specification of its exact location within these broad anatomical regions.
This code is appropriate when diagnostic imaging or biopsy confirms a benign neoplasm within the respiratory tract (e.g., lung, bronchus, trachea) or other intrathoracic structures (e.g., mediastinum, pleura), but the medical record lacks documentation specifying the exact site. It is used when the physician's documentation explicitly states "benign neoplasm of respiratory organ, site unspecified" or similar phrasing.
