Introduction of CPT codes for arthrocentesis

There are changes in CPT codes for arthrocentesis which we are using in interventional radiology coding. In interventional radiology, we will be having combined new codes in place of deleted old codes. CPT codes for arthrocentesis have separate procedure code for small, intermediate and large joint. The codes will include the ultrasound guidance, hence no need of coding guidance separately. Also, the CPT codes will be used for coding for aspiration and/or injection procedures done on joints.

Coding of guidance with CPT codes for arthrocentesis

As we know the CPT codes for arthrocentesis are combined codes and include ultrasound guidance, but there are no codes given for guidance other ultrasound like fluoroscopic guidance. The CPT codes are used only when done with ultrasound guidance, for arthrocentesis procedures with fluoroscopic guidance still are in question. Hope with the use of CPT codes we will overcome this confusion. Let’s check out these arthrocentesis CPT codes.

20604 Arthrocentesis, aspiration and/or injection, small joint or bursa (e.g., fingers, toes); with ultrasound guidance, with permanent recording and reporting

20606 Arthrocentesis, aspiration and/or injection, intermediate joint or bursa (e.g., temporomandibular, acromioclavicular, wrist, elbow or ankle, olecranon bursa); with ultrasound guidance, with permanent recording and reporting

20611 Arthrocentesis, aspiration and/or injection, major joint or bursa (e.g., shoulder, hip, knee, subacromial bursa); with ultrasound guidance, with permanent recording and reporting
