Malignant neoplasm of unsp part of unsp bronchus or lung

This code signifies a primary cancerous tumor originating in the lung or bronchus when the specific location within these structures is not documented. It indicates a malignant growth of pulmonary tissue without further anatomical precision.

Apply this code when medical record documentation confirms a primary malignant neoplasm of the lung or bronchus, but the physician's notes do not specify the lobe, segment, or even whether it's bronchial or pulmonary. This code is appropriate when the laterality (left/right) is also unspecified.

• Avoid using this code if any more specific anatomical detail (e.g., upper lobe, main bronchus) is documented.
• Always query the provider for greater specificity regarding the tumor's location and laterality if possible.
• This code should be a last resort when no further information can be obtained regarding the primary site.
