Benign neoplasm of intrathoracic organ, unspecified

This code signifies the presence of a non-cancerous growth within an intrathoracic organ, such as the heart, mediastinum, or thymus, when the specific organ involved is not documented. It indicates a benign tumor of an internal chest structure without further anatomical detail.

Use this code when documentation confirms a benign neoplasm located within the thoracic cavity, but the precise intrathoracic organ (e.g., heart, mediastinum, pleura, thymus, or other specified intrathoracic organs) is not identified. This code is appropriate when the physician's notes state "benign intrathoracic mass, site unspecified" or similar.

• Avoid using this code if a more specific benign neoplasm code for a particular intrathoracic organ (e.g., D15.0 for heart, D15.1 for mediastinum) can be assigned.
• Query the provider for clarification on the specific organ involved if possible to allow for more precise coding.
• This code should not be used for benign neoplasms of the lung (D14.3-) or bronchus (D14.2), which have their own specific codes.
