Purpose:
To study trends in volume and reimbursement for paracentesis and thoracentesis by physicians and advanced practice providers (APPs) after the introduction of discreet Current Procedural Terminology codes for image guidance.
Methods:
Medicare claims for 2012 to 2018 (paracentesis) and 2013 to 2018 (thoracentesis) were extracted using Current Procedural Terminology codes for blind and image-guided paracentesis and thoracentesis. Total volumes were analyzed by provider specialty. Nonfacility reimbursement and relative value units were compared.
Results:
For blind paracentesis, volume decreased from 17,393 to 12,226 procedures from 2012 to 2018. Conversely, volume of image-guided paracentesis increased from 171,631 to 253,834 procedures. Radiology performed the majority of image-guide paracentesis (83.9% in 2012 and 77.1% in 2018). Volume and relative share for APPs dramatically increased (from 10.2% to 15.8%). For blind thoracentesis, volume decreased from 26,716 to 15,075 procedures from 2013 to 2018. Conversely, volume of image-guided thoracentesis increased from 187,168 to 222,673 procedures. Radiology performed the majority of image-guided thoracentesis (73.6% in 2013 and 66.2% in 2018). Volume and relative share for APPs dramatically increased (from 7.7% to 12.9%). Although reimbursement for both image-guided paracentesis and thoracentesis decreased, their reimbursement remained higher than that of blind paracentesis and thoracentesis throughout the study period.
Conclusion:
A higher percentage of these procedures are being performed using image guidance; radiologists performed a growing number but declining percentage of image-guided paracentesis and thoracentesis. APPs are playing an increasing role, particularly using image guidance. Given decreasing reimbursement for these procedures, APPs can provide a large cost advantage in procedural radiology practices.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
