3 Simple Requirements for Medicare to Cover Your Knee Gel

Good News for Medicare Beneficiaries

Medicare has covered viscosupplementation (gel/HA injections) for knee osteoarthritis since 1997. This isn’t experimental or new—it’s an established, medically-validated treatment option.

With just 3 requirements, you may qualify for this non-surgical treatment that provides 6-12 months of relief.


The 3 Requirements

Requirement #1: Confirmed Knee Osteoarthritis Diagnosis

What You Need: An X-ray showing osteoarthritis of the knee

What Qualifies:

  • Joint space narrowing
  • Bone spurs (osteophytes)
  • Bone density changes (sclerosis)

Why It Matters: Medicare needs objective evidence that osteoarthritis is present. An X-ray provides this documentation.

Requirement #2: Failed Conservative Treatment

What You Need: Documentation that you’ve tried other treatments first

What Qualifies:

  • Physical therapy
  • Over-the-counter pain relievers (NSAIDs)
  • Weight management efforts
  • Activity modification
  • Other conservative measures

Why It Matters: Medicare considers viscosupplementation after simpler treatments haven’t provided adequate relief.

Requirement #3: Active Medicare Part B Coverage

What You Need: Active Medicare Part B enrollment

Part B Covers:

  • Outpatient medical services
  • Doctor visits
  • Injections and procedures

Important: If you have Medicare Advantage, coverage follows Medicare guidelines but your plan may have additional requirements.

Office visitYes
Injection procedureYes
Hyaluronic acid medicationYes
X-ray imagingYes
Fluoroscopy guidanceYes

What You’ll Pay

With Original Medicare (Part B):

After meeting your annual deductible ($240 in 2024):

  • Medicare pays 80% of the approved amount
  • You pay 20% coinsurance
  • Typical out-of-pocket: $100-$300 per knee

If you have a Medigap supplement:

  • Plans F, G, and others may cover your 20%
  • Your out-of-pocket may be $0 after deductible

Medicare Advantage Plans

If you have Medicare Advantage (Part C):

Important Differences:

  • Must cover what Original Medicare covers
  • May require prior authorization
  • Must use in-network providers
  • Copays vary by plan
  • Call the number on your card to verify specifics

Tip: Ask about prior authorization requirements before scheduling.


How to Ensure Coverage

Step 1: Get Proper Documentation

Make sure your medical record includes:

  • X-ray results showing knee osteoarthritis
  • Notes about conservative treatments you’ve tried
  • Documentation of ongoing pain/functional limitations
  • Your provider’s statement of medical necessity

Step 2: Choose the Right Provider

Work with a provider who:

  • Accepts Medicare assignment
  • Has experience with viscosupplementation
  • Uses imaging guidance for accuracy
  • Will handle prior authorization if needed

Step 3: Verify Before Treatment

Before your procedure:

  • Confirm your Part B is active
  • Ask about your specific out-of-pocket cost
  • Check if prior authorization is required (for MA plans)
  • Bring your Medicare card to the appointment
