HCPCS Code J7325: Hyaluronan or Derivative, Synvisc or Synvisc-One, for Intra-Articular Injection, 1 mg

Each Synvisc injection is 16 mg. Bill 16 units per injection. If a series of up to 3 injections is given, each injection is billed separately. The EJ modifier may be required for the second and third injections, depending on payer guidelines.

Bill 48 units of J7325 for the one-time Synvisc-One dose.

For bilateral knee injections, indicate 2 injections (or double the units as appropriate per payer) and append the -50 modifier to the CPT code for the procedure (e.g., 20610). J7325 units are billed based on the mg administered per knee.
