Aetna Plan Overview

Aetna is a major health insurer serving over 23 million members across the United States. In 2018, CVS Health acquired Aetna, creating one of the largest healthcare companies in America. This merger affects how pharmacy benefits and medical coverage work together for Aetna members.

For joint pain patients, Aetna offers coverage through several plan types:

  • Employer-sponsored plans (PPO, HMO, POS)
  • Individual marketplace plans (ACA/Obamacare)
  • Medicare Advantage plans (for those 65+)
  • Medicaid managed care (in select states)

Coverage for knee injections and joint treatments varies by plan. This guide explains what Aetna covers, what you will pay, and how to get approved.

Hyaluronic Acid Injections (Gel Shots)

Covered with Prior Authorization

Aetna covers most FDA-approved hyaluronic acid products for knee osteoarthritis. Popular brands include Synvisc-One, Euflexxa, Gel-One, and Supartz. Your provider must get approval before treatment.

Coverage requirements:

  • X-ray or MRI confirming knee osteoarthritis
  • At least 3 months of failed conservative care (PT, medications)
  • Documented pain and functional limitation
  • You are not ready for or want to avoid knee replacement

Cortisone Injections

Aetna covers cortisone (corticosteroid) injections for joint pain and inflammation. These shots typically do not require prior authorization. Your doctor can provide them during a regular office visit.

Coverage requirements:

  • Medical necessity documented
  • Appropriate diagnosis (arthritis, bursitis, tendinitis)

Physical Therapy

Physical therapy is covered under most Aetna plans. However, visit limits vary significantly:

  • Some plans cover 20-30 visits per year
  • Other plans have no set limit if medically necessary
  • In-network providers cost less than out-of-network

Check your specific plan documents or call member services to confirm your PT benefits.

What Aetna Does NOT Cover

Not Covered by Aetna
  • PRP (Platelet-Rich Plasma): Aetna considers PRP experimental and investigational
  • Stem cell injections: Not covered under standard policies
  • Prolotherapy: Considered experimental

These treatments require full out-of-pocket payment.


The Precertification Process

Aetna calls prior authorization “precertification.” For hyaluronic acid injections, your provider must get approval before your treatment.

How Precertification Works

1
Your doctor submits a request

Includes your diagnosis, imaging results, and treatment history

2
Aetna reviews medical necessity

Checks if you meet their clinical policy criteria

3
Decision issued within 15 days

Urgent requests may be processed faster

4
Treatment scheduled after approval

Authorization is valid for a specific time period

Documentation Your Doctor Needs

  • Imaging reports: X-rays showing joint space narrowing or bone spurs
  • Treatment records: Dates and outcomes of PT, medications, and other treatments
  • Pain assessment: Scores and descriptions of how pain affects your daily life
  • Medical necessity letter: Statement explaining why HA injections are appropriate

For detailed guidance, read our Prior Authorization Guide for Gel Injections.


Step Therapy Requirements

Aetna may require you to try other treatments before approving hyaluronic acid injections. This is called “step therapy.”

Typical Step Therapy Progression

Step 1: Conservative Care (3+ months)

  • Over-the-counter pain relievers (acetaminophen, ibuprofen)
  • Physical therapy
  • Weight management
  • Activity modification

Step 2: Prescription Options

  • Stronger NSAIDs
  • Topical treatments
  • Cortisone injection(s)

Step 3: Viscosupplementation

  • Hyaluronic acid injections approved after steps 1-2 fail

Important: Keep records of all treatments you have tried. Aetna will want to see proof that conservative care did not provide adequate relief.


Understanding Your Costs

What You Will Pay

Your out-of-pocket costs depend on your specific Aetna plan. Here are typical ranges:

Cost TypeTypical Amount
Office visit copay$30-$75
Specialist copay$40-$100
Coinsurance20-40% after deductible
Annual deductible$500-$3,000+
Out-of-pocket maximum$3,000-$9,100

Factors That Affect Your Cost

  1. Plan type: PPO, HMO, and high-deductible plans have different cost structures
  2. Network status: In-network providers have negotiated lower rates
  3. Deductible status: Services before meeting your deductible cost more
  4. Specific HA product: Some plans have preferred brands

In-Network vs. Out-of-Network

Save Money: Use In-Network Providers

Using an in-network provider can save you hundreds of dollars:

  • In-network: Lower copay, negotiated rates, no balance billing
  • Out-of-network: Higher costs, separate deductible, balance billing possible

Tip: Always verify a provider is in your Aetna network before scheduling treatment.

CVS Health and Pharmacy Benefits

Since the CVS-Aetna merger, your pharmacy benefits may be managed through CVS Caremark. For injectable medications like hyaluronic acid:

  • Some plans require the HA product to come from a specialty pharmacy
  • CVS specialty pharmacy may provide the medication to your doctor
  • This can affect which HA brands are covered or preferred

Ask your Aetna plan about any specialty pharmacy requirements.


The Appeals Process

If Aetna denies your request for coverage, you have the right to appeal.

Common Denial Reasons

Precertification was not obtained before treatment
Documentation of failed conservative treatment is incomplete
Diagnosis does not meet clinical policy criteria
Treatment received from an out-of-network provider

How to File an Appeal

Step 1: Review Your Denial Letter

  • Understand the specific reason for denial
  • Note the deadline for filing an appeal (usually 60-180 days)

Step 2: Gather Supporting Documents

  • Complete medical records
  • All imaging reports
  • Records of every treatment tried
  • Letter from your doctor explaining medical necessity

Step 3: Submit Your Appeal

  • Mail or fax to the address on your denial letter
  • Include a clear explanation of why you believe coverage should be approved
  • Attach all supporting documents

Step 4: Request Peer-to-Peer Review

  • Your doctor can speak directly with an Aetna medical director
  • This often resolves issues faster than written appeals

Step 5: External Review (If Needed)

  • If Aetna denies your internal appeals, you can request an independent external review
  • Contact your state insurance commissioner if you need additional help

Tips for a Successful Appeal

File your appeal as soon as possible (within 60 days is best)
Include ALL medical records, not just summaries
Ask your doctor to write a detailed medical necessity letter
Request a peer-to-peer review between your doctor and Aetna
Keep copies of everything you submit
