What 74230 covers
This study uses fluoroscopy and recorded images to observe swallowing as the patient takes oral contrast material of selected consistencies. It can show how a bolus moves through the oral and pharyngeal phases and whether material enters the airway. Radiologists commonly provide the imaging interpretation, while speech-language pathologists may assess swallowing mechanics during the examination. Studies are performed in radiology departments and other settings equipped for fluoroscopy, often for patients with dysphagia, coughing during meals, or suspected aspiration.
Report 74230 for the recorded fluoroscopic assessment of swallowing function, rather than an examination focused primarily on esophageal structure or transit. The record should support the swallowing concern, the imaging performed, and the findings interpreted. CMS recognizes professional and technical components: report modifier 26 for the professional interpretation, modifier TC for the equipment and staff, or no modifier for the global service. A speech-language pathologist's separately furnished swallowing evaluation may be reported with 92611 when its work is documented.

How to choose
- 74220Esophagram
- Choose 74230 for recorded assessment of swallowing mechanics and airway protection. Choose 74220 when the examination is directed primarily at the esophagus and its transit.
- 74210Contrast X-ray
- 74210 focuses on radiographic examination of the pharynx or cervical esophagus. 74230 captures swallowing function dynamically with recorded imaging.
- 92611Swallow study
- 74230 represents the radiologic service and interpretation. 92611 represents the speech-language pathologist's functional swallowing evaluation when separately furnished and documented.
74230 billing questions
How does 74230 differ from an esophagram?
74230 evaluates swallowing function dynamically, including bolus movement and airway protection. An esophagram such as 74220 focuses on the esophagus and its transit.
When should modifier 26 or TC be used?
Use modifier 26 for the professional interpretation and modifier TC for the technical service, including equipment and staff. Submit without a component modifier when billing the global service.
Can 92611 be reported for the same examination?
A speech-language pathologist may report 92611 for a separately furnished functional swallowing evaluation. Documentation should distinguish that evaluation from the radiologic interpretation reported with 74230.
What documentation supports 74230?
Document the swallowing symptoms or concern, the fluoroscopic assessment and recorded images, and the interpreted findings, including relevant observations of bolus movement or airway entry.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
