Final answer:
The statement is false; the National Correct Coding Initiative does include guidelines for coding procedures on the mediastinum and diaphragm.
Step-by-step explanation:
The statement that "There are no National Correct Coding Initiative (NCCI) guidelines for coding procedures completed on the mediastinum and diaphragm" is false. The National Correct Coding Initiative has guidelines and edits that apply to the wide range of medical procedures, including those for the thoracic cavity, specifically the mediastinum and diaphragm. These comprehensive NCCI guidelines are designed to prevent improper coding such as unbundling and incorrect billing, and they also include procedures related to the superior mediastinum, pleural cavity, and pericardial cavity within the mediastinum.
