Which medicare plan requires prior authorization?

Nearly 99% of Medicare Advantage (Part C) plans and all standalone Medicare Part D prescription drug plans require prior authorization for specific services or medications.

Medicare Advantage (Part C)

  • Standard practice: Almost all Medicare Advantage plans use prior authorization to control costs.
  • Common services: Preapproval is frequently required for specialist visits, expensive tests, durable medical equipment, skilled nursing facility stays, and inpatient surgeries.

Medicare Part D

Original Medicare (Part A and Part B)

Why is Aetna cancelling Medicare Advantage plans?

Aetna is cancelling and scaling back dozens of Medicare Advantage plans primarily due to rising medical utilization costs and inadequate government reimbursements from the Centers for Medicare & Medicaid Services (CMS) that fail to keep pace with inflation.

Most users on Reddit agree that increasing care costs and profitability challenges are driving major insurers like Aetna, Humana, and UnitedHealthcare to retreat from unprofitable markets.

📊 Key Drivers Behind Aetna's Cuts

  • 📈 Rising Medical Costs: Higher-than-expected doctor visits, procedures, and post-pandemic care utilization have strained insurer margins.
  • 📉 Lower Government Payments: CMS benchmark updates and reimbursement rates have not kept up with inflation or care costs.
  • 📌 Profitability & Footprint Reduction: Aetna is withdrawing or trimming options (especially PPO plans) across dozens of states to focus on sustainable service areas.
  • 🔍 Broker Commission Adjustments: Aetna and other carriers have cut or halted broker commissions on specific plans to manage acquisition expenses.

  • Plan Exclusions: Many standard Aetna commercial plans have removed Zepbound from coverage for weight loss unless prescribed for alternative indications like obstructive sleep apnea (OSA).
  • Clinical Criteria: When prior authorization is allowed, Aetna generally requires proof of a body mass index (BMI) of 30 or higher (or 27+ with a weight-related health condition like high blood pressure or high cholesterol) and documentation of at least 6 months of participation in a structured weight-management program.

Who is better, UnitedHealthcare or Aetna?

Neither UnitedHealthcare is universally better than Aetna; the right choice depends on your specific needs, location, and whether you want a larger provider network or better quality ratings.

Network and Coverage

  • UnitedHealthcare: Offers a massive national footprint with a large provider network available across all 50 states. It often stands out for robust individual and health savings account (HSA) options.
  • Aetna: Owned by CVS Health, it provides near-nationwide coverage and frequently scores higher on government quality ratings, particularly for Medicare Advantage plans.

Costs and Perks

  • UnitedHealthcare: Tends to feature lower maximum out-of-pocket spending caps on certain Medicare plans, though general plans can sometimes carry higher price points.
  • Aetna: Frequently features a higher percentage of $0-premium plans and integrates well with CVS pharmacy benefits (CVS Caremark).

Customer Satisfaction

  • Both major insurers often score around the industry average or slightly below on independent customer satisfaction surveys, meaning experiences can vary significantly depending on your local market.

Why are doctors leaving Aetna?

Doctors and healthcare systems leave Aetna's network primarily due to disagreements over reimbursement rates, heavy administrative burdens, and failed contract negotiations.

For comprehensive details on why provider networks change, you can review the Aetna Medicare Provider Network Changes guide.

Key Reasons Providers Leave Aetna

  • Low Reimbursement Rates: Providers often state that Aetna's payment rates do not keep up with inflation, rising operational costs, or the rates paid by other insurers.
  • Administrative Hassles: Doctors face extensive paperwork, prior authorization (precertification) requirements, and claim denials that increase office overhead and delay care.
  • Contract Impasses: When annual or multi-year contracts expire, Aetna and large medical groups (such as university health systems or regional hospitals) frequently fail to agree on financial terms, forcing providers out-of-network.
  • Aetna's Market Reductions: Parent company CVS Health has pulled back from specific regional markets, scaling back certain Affordable Care Act (ACA) exchange footprints and Medicare Advantage plans, which structurally alters local networks.
