What 20605 covers
Orthopedists, rheumatologists, sports medicine clinicians, and other qualified practitioners use this service to withdraw fluid from or inject medication into an intermediate joint or bursa. Common targets include the wrist, elbow, ankle, acromioclavicular joint, and temporomandibular joint. It is performed in settings such as an office, clinic, or hospital outpatient department when the clinical need calls for treatment or fluid sampling at one of these sites without ultrasound guidance.
Select the code based on the treated site and whether aspiration, injection, or both are performed; document the specific joint or bursa, laterality, procedure, and clinical reason. This minor procedure has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, Medicare pays the highest-valued procedure in full and applies the standard reduction to the others. For bilateral treatment reported with modifier 50, CMS pays 150%. Assistant-at-surgery services are not paid; co-surgeons and team surgery are not permitted.

20605 billing questions
How does this differ from codes for small or major joints?
Choose the code level based on the joint or bursa treated. This code is for intermediate sites such as the wrist, elbow, ankle, acromioclavicular joint, or temporomandibular joint.
Can this code be reported when ultrasound guides the procedure?
No. For ultrasound-guided aspiration or injection of an intermediate joint or bursa, use 20606 instead.
What should the procedure note identify?
Document the specific joint or bursa, side, whether fluid was aspirated or medication injected, and the clinical reason for the procedure.
How is bilateral treatment reported under the CMS rule?
Report bilateral treatment with modifier 50; CMS pays 150% for the bilateral procedure.
Does the code include the injected medication?
The code describes the aspiration or injection procedure, not a particular drug. It does not by itself identify or report the medication administered.
