UnitedHealthcare Coverage Overview

UnitedHealthcare (UHC) is the largest private health insurer in the United States. For knee osteoarthritis patients, the good news is that UHC lists hyaluronic acid injections as “proven and medically necessary” in their medical policy—meaning coverage is available when criteria are met.

However, coverage details vary significantly by plan type, so understanding your specific benefits is essential.

UHC’s Position on Hyaluronic Acid

Official Medical Policy

UnitedHealthcare’s medical policy states that sodium hyaluronate (HA) injections are “proven and medically necessary” for the treatment of knee osteoarthritis when specific criteria are met.[1]

Coverage Criteria:

Documented osteoarthritis of the knee
Failed conservative measures (PT, oral medications)
Pain interfering with function or daily activities

What “Proven and Medically Necessary” Means

This classification is stronger than many insurers provide. It indicates:

  • UHC acknowledges clinical evidence supports HA
  • Coverage is policy-based, not subject to case-by-case review (when criteria met)
  • Denials are less common than with insurers who call HA “experimental”

Prior Authorization Requirements

What to Expect

Most UHC plans require prior authorization for HA injections. This means:

  1. Your provider submits a request before treatment
  2. UHC reviews the request against medical policy
  3. Approval is issued (or denied with reason)
  4. Treatment proceeds once approved

Prior Auth Process

1
Provider submits request

Includes diagnosis, imaging, treatment history, and medical necessity statement

2
UHC reviews

Typically 1-5 business days for standard requests

3
Decision issued

Approval, denial, or request for additional information

4
Treatment scheduled

Once approved, proceed with injection

Tips for Smooth Approval

Ensure X-rays clearly show osteoarthritis
Document conservative treatment attempts and failures
Describe functional limitations specifically
Use correct diagnosis codes (M17.x for knee OA)

Plan Variations

Employer-Sponsored Plans

Coverage varies by employer. Some employers:

  • Include HA without restrictions
  • Require step therapy (try cortisone first)
  • Have higher or lower copays
  • May exclude HA altogether (check your SPD)

Individual/ACA Marketplace Plans

Coverage depends on the specific plan level and benefits. Generally:

  • Silver and Gold plans more likely to cover
  • Prior authorization typically required
  • In-network providers strongly preferred

Medicare Advantage (UHC branded)

UHC Medicare Advantage plans typically follow Medicare coverage rules:

  • HA covered under Part B equivalent
  • Prior authorization may or may not apply
  • Coverage matches traditional Medicare in most cases

Costs and Out-of-Pocket

What You’ll Typically Pay

Cost ComponentTypical Range
Deductible$0-$1,500+ (varies by plan)
Copay (specialist)$30-$75 per visit
Coinsurance20-40% after deductible
Out-of-pocket maxPlan-specific

In-Network vs. Out-of-Network

Important: Going out-of-network can significantly increase costs:

  • Higher deductible applies
  • Higher coinsurance (often 40-50%)
  • Balance billing possible
  • May not count toward in-network out-of-pocket max

Always verify your provider is in-network before treatment.


If You’re Denied

Common Denial Reasons

  1. Prior authorization not obtained - Most common fixable issue
  2. Insufficient documentation - Need more treatment history
  3. Criteria not met - May need to try other treatments first
  4. Out of network - Higher costs or no coverage
  5. Plan exclusion - HA specifically excluded (rare)

Appeal Process

UHC Appeal Steps:

  1. Request written denial explanation - Call number on denial letter
  2. Gather documentation - Medical records, imaging, treatment history
  3. Provider letter of medical necessity - Explains why HA is appropriate
  4. Submit formal appeal - Within 180 days of denial
  5. Request peer-to-peer - Your doctor speaks with UHC medical director
  6. External review - If internal appeals fail
