By Joint Pain Authority Team
Key Takeaways
- Gel-One injection self-pay cost ranges from $400 to $900 depending on provider, location, and discounts
- With Medicare Part B, patients typically pay the 20% coinsurance — roughly $80–$200 for the injection after meeting the annual deductible
- Gel-One is billed under HCPCS code J7320 (hyaluronan or derivative, Gel-One, for intra-articular injection, per dose)
- Most private insurance plans cover Gel-One when medical necessity criteria are met, though prior authorization is typically required
- Gel-One’s single-injection convenience eliminates multiple office visit copays compared to 3–5 injection series brands
- Allergy alert: Gel-One is avian-derived (rooster comb) — it is not safe for patients with bird or egg allergies
Gel-One is a single-injection hyaluronic acid treatment for knee osteoarthritis made by Zimmer Biomet. One injection can provide up to 6 months of pain relief from a single office visit. If you’re considering Gel-One, understanding exactly what it costs — with insurance, without insurance, and compared to alternatives — is essential for planning your care.
This guide covers 2026 pricing for all scenarios: Medicare Part B, private insurance, and self-pay, along with tips for minimizing your out-of-pocket costs.
What Is Gel-One and Why Does It Cost What It Does?
Gel-One is a single-injection hyaluronic acid (HA) product manufactured by Zimmer Biomet. It delivers 30 mg of cross-linked sodium hyaluronate in a 3 mL syringe. Unlike biosynthetic brands such as Durolane or Monovisc, Gel-One is avian-derived — the hyaluronic acid comes from rooster combs.
Gel-One received FDA approval in 2011 and remains one of only two avian-derived single-injection HA products (alongside Synvisc-One).
This matters for cost because:
- Single injection vs. series: Gel-One requires only one office visit, while brands like Euflexxa (3 injections) or Supartz FX (5 injections) require multiple visits — each with its own copay and office fee
- Cross-linked formula: Gel-One’s cross-linked hyaluronic acid is designed for longer retention in the joint than non-cross-linked alternatives
- Avian sourcing: Manufacturing from rooster combs is a well-established process, which can keep production costs lower than newer biosynthetic methods
- Allergy consideration: Because Gel-One is avian-derived, patients with bird or egg allergies must use a non-avian alternative like Durolane or Monovisc
Gel-One Cost Without Insurance (Self-Pay)
Self-Pay Price Ranges for Gel-One (2026)
| Cost Component | Range |
|---|---|
| Gel-One injection (medication only) | $400–$900 |
| Office visit fee | $50–$200 |
| Imaging guidance (recommended) | $100–$300 |
| Total self-pay range | $550–$1,400+ |
Why Prices Vary So Much
Gel-One pricing varies significantly because:
- Provider markup: Clinics purchase Gel-One at wholesale and mark up the price — office-based practices typically charge less than hospital outpatient departments
- Geographic location: Urban markets and high cost-of-living areas charge more
- Facility type: Hospital outpatient departments add facility fees ($200–$500+), while office-based clinics typically include everything in one price
- Wholesale pricing: Direct-to-provider wholesale prices are lower than what patients see — but cash-pay patients can sometimes negotiate closer to these rates
Tip: Call providers and ask for their “self-pay price” for Gel-One — many offer discounted cash rates. Also, ask whether the imaging guidance (fluoroscopy or ultrasound) is included in the quoted price or billed separately.
Gel-One Cost With Medicare Part B
Medicare Coverage for Gel-One
Coverage status: Yes, Medicare Part B covers Gel-One (J7320)
Typical patient cost with Medicare:
- Annual Part B deductible: $257 (2025; verify current year)
- After deductible: You pay 20% coinsurance of the Medicare-approved amount
- Medicare pays 80% of the approved amount
Estimated patient out-of-pocket:
- If deductible already met: ~$80–$200 per injection (20% of the Medicare-approved amount)
- If deductible not yet met: $257 + 20% of remainder
How Medicare Bills Gel-One
Medicare uses HCPCS code J7320 for Gel-One (Hyaluronan or derivative, Gel-One, for intra-articular injection, per dose). Gel-One comes as a single 30 mg/3 mL syringe, and providers bill 1 unit of J7320 per injection.
Your 20% coinsurance share typically comes to approximately $80–$200 — though actual costs vary by region, provider type, and whether imaging guidance is billed separately.
Medicare Coverage Requirements
Medicare requires documentation that:
Medicare Advantage Plans
If you have a Medicare Advantage (Part C) plan, Gel-One coverage may differ from Original Medicare. Some Medicare Advantage plans require prior authorization, preferred networks, or specific prior treatment failure requirements. Always verify coverage with your specific plan before scheduling.
Gel-One Cost With Private Insurance
Most commercial insurance plans cover Gel-One for knee osteoarthritis when medical necessity criteria are met, similar to Medicare requirements.
Typical private insurance process:
- Prior authorization is almost always required — your provider’s office handles this
- Step therapy may require documentation of failed conservative treatments
- Copay or coinsurance: Varies by plan — typically $50–$200 per injection
- Deductible: If not yet met, you pay the full allowed amount until the deductible is reached
Tip: Have your provider’s office call to verify coverage and get prior authorization before your appointment. A reputable clinic handles this verification proactively.
Gel-One vs. Other Single-Injection Brands: Cost Comparison
Gel-One is one of four FDA-approved single-injection HA products. Understanding how its cost compares to alternatives helps you discuss options with your doctor.
| Brand | Source | Self-Pay Estimate | Medicare Coverage | Allergy-Safe |
|---|---|---|---|---|
| Gel-One | Avian (rooster comb) | $400–$900 | Yes (J7320) | No — not safe for bird/egg allergies |
| Synvisc-One | Avian (rooster comb) | $600–$1,200 | Yes (J7321) | No — not safe for bird/egg allergies |
| Durolane | Non-animal (bacterial) | $300–$1,465 | Yes (J7318) | Yes — bird/egg safe |
| Monovisc | Non-animal | $500–$1,000 | Yes (J7322) | Yes — bird/egg safe |
All four are covered by Medicare at similar payment levels. Gel-One is typically the most affordable avian-derived single-injection option, but patients with bird or egg allergies must choose Durolane or Monovisc instead. See our bird allergy guide for details.
Gel-One vs. Multi-Injection Series: True Cost Comparison
Single-injection Gel-One may look more expensive per dose, but the total cost often comes out similar to — or less than — a multi-injection series when you factor in all costs.
| Gel-One (Single) | Euflexxa (3 injections) | Supartz FX (5 injections) | |
|---|---|---|---|
| Injections needed | 1 | 3 | 5 |
| Office visits | 1 | 3 | 5 |
| Medication cost (self-pay) | $400–$900 | $300–$900 total | $500–$1,000 total |
| Office visit copays | 1x | 3x | 5x |
| Time commitment | 1 visit | 3 weeks | 5 weeks |
| Work/travel disruption | Minimal | Moderate | High |
The hidden cost of series injections is time and visit copays. For Medicare patients with a $20 copay per visit, Gel-One saves $40 vs. Euflexxa and $80 vs. Supartz FX in visit copays alone — partly offsetting any medication cost difference.
Important: Bird and Egg Allergy Warning
Gel-One Is Not Safe for Patients With Bird or Egg Allergies
Gel-One is manufactured from rooster combs (avian-derived hyaluronic acid). If you have a known allergy to birds, poultry, feathers, or eggs, Gel-One is not recommended for you.
Safe single-injection alternatives include:
- Durolane — Non-animal (bacterial fermentation), $300–$1,465 self-pay
- Monovisc — Non-animal sourced, $500–$1,000 self-pay
Both are covered by Medicare Part B and provide similar single-injection convenience.
Always tell your doctor about any bird or egg allergies before receiving any gel injection. Read our complete guide: Bird or Egg Allergy? Safe Knee Gel Shot Options.
Hidden Costs to Budget For
When planning for Gel-One, account for these additional expenses beyond the injection itself:
Frequently Overlooked Costs
Office/consultation visit fee: $50–$200 (may be separate from injection fee)
Imaging guidance: $100–$300 if billed separately — studies show imaging guidance improves injection accuracy by 30%, so it’s worth the cost. Medicare covers fluoroscopy with the injection.
Pre-injection X-ray: If not already done, you may need knee X-rays ($100–$300 without insurance)
Follow-up visit: Some providers schedule a follow-up 4–6 weeks post-injection to assess response
Facility fees: Hospital outpatient departments charge a facility fee (often $200–$500+) on top of the injection fee — office-based clinics typically don’t

Frequently Asked Questions
Does Medicare cover Gel-One injections?
Yes. Medicare Part B covers Gel-One (billed as J7320) for knee osteoarthritis when medically necessary. You typically pay 20% coinsurance after meeting your annual Part B deductible of $257 (2025 figure). Your actual out-of-pocket cost per injection is typically $80–$200 depending on your deductible status and the provider’s Medicare-approved amount.
How much does Gel-One cost without insurance?
Without insurance, Gel-One costs approximately $400–$900 at most providers for the medication alone. The total self-pay cost including the office visit and imaging guidance typically ranges from $550–$1,400+. Ask providers directly for their cash-pay rate — prices vary significantly between clinics.
Is Gel-One safe if I have a bird or egg allergy?
No. Gel-One is avian-derived (manufactured from rooster combs) and is not recommended for patients with bird, poultry, feather, or egg allergies. If you have these allergies, safe single-injection alternatives include Durolane (non-animal, bacterial fermentation) and Monovisc (non-animal). Both are covered by Medicare. See our bird allergy guide for more details.
How does Gel-One compare to Synvisc-One in cost?
Both Gel-One and Synvisc-One are avian-derived single-injection options. Gel-One typically costs $400–$900 self-pay, while Synvisc-One runs $600–$1,200. Both are covered by Medicare Part B at similar payment levels. Gel-One tends to be the more affordable avian-derived single-injection option.
Does prior authorization affect the cost of Gel-One?
Prior authorization doesn’t directly change the price, but failing to get it before your injection could result in a claim denial — leaving you responsible for the full cost. Most reputable clinics handle prior authorization for you before scheduling. Always confirm prior auth is obtained before your appointment.
How often can I get Gel-One and how does that affect annual cost?
Medicare allows repeat Gel-One treatment every 6 months when the previous course was effective. Annual cost for two treatments with Medicare (20% coinsurance, deductible already met) is typically $160–$400. Self-pay patients would pay $800–$1,800+ annually for twice-yearly treatment.
What’s the HCPCS code for Gel-One for insurance purposes?
Gel-One is billed using HCPCS code J7320 (Hyaluronan or derivative, Gel-One, for intra-articular injection, per dose). One 30 mg/3 mL syringe = 1 unit of J7320. The administration itself is typically billed under CPT 20610 (arthrocentesis, aspiration and/or injection, major joint).
