Can CPT 27447 be billed with cpt 20680?

CPT 27447 (arthroplasty, knee, condyle and plateau) and CPT 20680 (arthrocentesis, aspiration, and/or injection into a major joint or bursa) can be billed together, but this depends on the specific circumstances of the procedures performed. If both procedures are medically necessary and distinct, appropriate modifiers should be applied to indicate that they are separate services. It's essential to check payer guidelines and documentation requirements to ensure compliance when billing these codes together.
