When your physician performs arthrocentesis to manage a patient's pain, you need to check if she used fluoroscopy during the procedure. Why? Coding will depend upon, among other factors, whether or not the physician used fluoroscopic guidance during the procedure. We got the chance to ask Amy Turner, RN, BSN, MMHC, CPC, vice president of revenue at Comprehensive Pain Specialists in Brentwood, Tenn., a few questions about pain-related arthrocentesis injections. Check out what she had to say, and remember her advice the next time you're coding for CPT® codes 20600 (Arthrocentesis, aspiration and/or injection, small joint or bursa (e.g., fingers, toes); without ultrasound guidance) through 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). Q: What types of patients need arthrocentesis 20600-20611? A: According to Turner, the most common presentations for pain-relieving arthrocentesis would be osteoarthritic conditions. These might include: Q: When might my provider perform a pain-relieving arthrocentesis injection? A: Your practice will mostly perform arthrocentesis injections on larger joints, Turner says. Example: A patient reports to the practice complaining of right knee pain. The physician diagnoses unilateral primary osteoarthritis in the patient's right knee. She then injects 40 mg of Depo-Medrol with ultrasound guidance. On the claim, you should report Q: Why might a physician need guidance during an arthroscopy? A: If the physician needs to use fluoroscopic guidance during an arthroscopy, it is likely because she had trouble with needle placement, Turner says. If the notes indicate that there were complications during needle placement for the arthrocentesis, and that complication resulted in the physician using fluoroscopy, you might need to report once of the following codes, depending on the specifics of the encounter: Q: Which J codes, and drugs, might you be able to code for with arthrocentesis? A: Your physician will typically inject steroids during pain-relieving arthrocentesis injections, Turner says. Some of the most common drugs include:
