A rheumatology office performs arthrocentesis of the knee with ultrasound guidance. What reporting concept should be applied?
Select an answer to reveal the explanation.
Short Explanation
Draining a knee and watching it on ultrasound can be two documented pieces of work—needle into the joint, plus imaging guidance. When CPT/payer rules allow separate guidance, don’t pretend guidance never existed or that you replaced the whole knee.
Full Explanation
Arthrocentesis is selected from joint aspiration/injection families by site. Ultrasound guidance may be separately reportable when documented and when CPT and payer rules permit distinct guidance reporting rather than inherent bundling. MRI and arthroplasty are unrelated service families for an office aspiration with guidance.
