What Is Supartz FX?
Supartz FX is a multi-injection hyaluronic acid treatment for knee osteoarthritis, manufactured by Bioventus. It contains low molecular weight sodium hyaluronate derived from avian (rooster comb) sources and is delivered as a series of 3 to 5 weekly injections.
With FDA approval dating back to 1996 (as Supartz, updated to Supartz FX), this product has the longest track record of any viscosupplementation brand in the United States.

Supartz FX Cost With Medicare Part B
Medicare Coverage for Supartz FX
Coverage status: Yes — Medicare Part B covers Supartz FX (J7321)
Billing code: J7321 (hylan or sodium hyaluronate, 10 mg per dose; Supartz FX 2.5 mL syringe = 25 mg = 2.5 units)
Typical patient cost per injection (after deductible):
- Approximately $50–$100 per injection (20% coinsurance)
- Full 3-injection course: $150–$300
- Full 5-injection course: $250–$500
Note: If the Part B deductible ($257 in 2025) hasn’t been met, first-injection costs will be higher.
3-Injection vs. 5-Injection Protocol: What Medicare Covers
Supartz FX has a flexible dosing schedule — 3 or 5 weekly injections. Medicare typically covers whichever protocol your provider prescribes as medically necessary. The 3-injection protocol is increasingly common due to convenience and similar outcomes.
If you have a Medicare Advantage plan, coverage rules may differ. Some plans require:
- Prior authorization before treatment
- Step therapy (specific sequence of treatments required first)
- Use of preferred provider networks
Always verify with your specific plan before scheduling.
The Real Cost of Multi-Injection Series: Visit Copays Add Up
One consideration often overlooked with multi-injection brands: each injection requires a separate office visit, and each visit generates a separate copay.
| Supartz FX (5 shots) | Synvisc-One (1 shot) | Durolane (1 shot) | |
|---|---|---|---|
| Injections | 5 | 1 | 1 |
| Office visits | 5 | 1 | 1 |
| Medicare copays (est. $30/visit) | ~$150 | ~$30 | ~$30 |
| Time off work | 5 mornings | 1 morning | 1 morning |
| Duration of relief | 6 months | 6 months | 6 months |
For patients with busy schedules, the convenience of a single-injection product may justify its slightly higher per-dose cost. For patients who prefer gradual relief build-up, the series approach may be preferable.
Frequently Asked Questions
How much does a full Supartz FX treatment cost with Medicare?
With Medicare Part B (after deductible is met), a full Supartz FX treatment course typically costs $150–$300 for 3 injections, or $250–$500 for 5 injections — the 20% coinsurance on each injection. Your actual cost depends on the Medicare-approved rate in your area and whether your deductible has been met.
Is Supartz FX covered by insurance?
Yes. Supartz FX is covered by Medicare Part B and most commercial insurance plans for knee osteoarthritis when medically necessary. Prior authorization is typically required for private insurance. Medicare generally does not require prior authorization but does require documentation of medical necessity.
How many Supartz FX injections does Medicare cover?
Medicare covers the number of injections prescribed by your physician as medically necessary — either 3 or 5 in a series. Medicare allows retreatment every 6 months if the previous course was effective.
What HCPCS code is used for Supartz FX billing?
Supartz FX is billed under J7321 (the same code used for Hyalgan and Synvisc). The code covers sodium hyaluronate or hylan injections at 10 mg per dose. Confirm with your provider’s billing department that the correct code is being used to avoid claim issues.
