Can I report a nasal endoscopy with a diagnostic drug induced sleep endoscopy?

No, when reporting CPT code 42975 for a diagnostic drug induced sleep endoscopy you cannot report a nasal endoscopy 31231 unless it is performed for a separate condition other than sleep disordered breathing and using a separate endoscope.
