What does a 5 star CMS rating mean?

Editorial team Published on

A 5-star CMS rating means "much above average" quality or excellent performance based on an evaluation by the Centers for Medicare & Medicaid Services (CMS).

Depending on what is being evaluated, a 5-star rating applies to different areas of healthcare:

Nursing Homes & Senior Care

For nursing homes listed on Medicare Care Compare, a 5-star overall rating places a facility in the top tier nationwide for care quality. It is calculated using three main categories:

  • Health Inspections: Results from state health surveys over three years, measuring safety, infection control, and compliance. Only the top 10% in each state earn 5 stars in this category.
  • Staffing: High numbers of direct-care nursing hours per resident daily and low staff/administrator turnover rates.
  • Quality Measures (QMs): Superior physical and clinical outcomes for short- and long-stay residents (such as preventing falls, pressure ulcers, or pain).

Medicare Advantage & Part D Plans

For insurance plans, a 5-star rating indicates excellent performance in member satisfaction and plan quality. CMS evaluates metrics like:

  • Customer service and handling of member appeals
  • Staying healthy (preventive screenings, vaccinations, and checkups)
  • Management of chronic conditions
  • Plans with 5 stars generally allow beneficiaries to enroll in that plan outside of the standard annual enrollment period.

Hospitals

For hospitals, the Overall Hospital Quality Star Rating combines various measures across multiple areas—such as safety of care, readmission rates, mortality, and patient experience—into a single summary score reflecting high-level performance.

How many CMS 5-star hospitals are there?

There are 384 to 385 hospitals with a 5-star rating from the Centers for Medicare & Medicaid Services (CMS) in the 2026 update.

Details of the 2026 CMS Ratings

  • Total 5-star hospitals: 384 (or 385, depending on the specific reporting extract), representing about 12% of rated facilities.
  • Total hospitals rated: 3,182 national facilities.
  • Comparison to last year: This is an increase from 290 five-star hospitals in 2025.
  • Evaluation categories: Mortality, safety of care, readmission rates, patient experience, and timely/effective care.

You can check individual hospital ratings directly through the CMS Provider Data Catalog.

What is a 5-star Medicare plan?

A 5-star Medicare plan is a top-performing health or prescription drug plan that earned the highest possible quality rating from the Centers for Medicare & Medicaid Services (CMS).

How Ratings Work

  • The Scale: CMS evaluates Medicare Advantage (Part C) and Part D prescription drug plans every year on a scale from 1 to 5 stars.
  • The Measures: Scores rely on dozens of unique quality and performance items. These include customer service, appointment wait times, member satisfaction, chronic condition management, and drug safety.
  • The Meaning: 5 stars means excellent performance. Fewer than 10% of plans typically achieve this status.

Key Benefits of a 5-Star Plan

  • Special Enrollment Period (SEP): If a 5-star plan is available in your area, Medicare lets you switch from your current plan to that 5-star plan one time between December 8 and November 30 outside of normal enrollment windows.
  • Quality Care: High ratings point to fewer member complaints, better care coordination, and reliable customer support.

Which CMS star rating is the highest?

The highest CMS star rating is 5 stars, which indicates excellent performance and quality.

What does a 5-star rating mean?

A 5-star rating means the highest level of quality, luxury, or performance available in that specific category.

Because a 5-star score is used across many different industries, its exact meaning depends on what is being rated:

Hotels and Accommodations

  • Luxury and Service: A 5-Star Hotel offers top-tier personalized service, 24-hour reception, fine dining, valets, concierges, and high-end room amenities.
  • Facilities: These properties typically feature spas, fitness centers, pools, and exceptional interior design.

Customer Reviews and Products

  • Complete Satisfaction: On digital platforms (like e-commerce or ride-sharing apps), 5 stars mean the user had a flawless or optimal experience.
  • Exceeded Expectations: It signals that the product or service matched its description and performed without any issues.

Government and Official Programs

  • Healthcare: The Five-Star Quality Rating System used by official agencies for nursing homes indicates quality that is "much above average" based on health inspections, staffing, and specific care metrics.
  • Food Hygiene: A 5-star food hygiene rating means a restaurant or food business has very good standards that fully comply with safety laws.

What does a CMS 5-Star rating mean?

A CMS 5-star rating means a nursing home or healthcare facility performs "much above average" and ranks among the highest-quality providers nationwide.

The Centers for Medicare & Medicaid Services (CMS) created the Five-Star Quality Rating System to help patients and families compare facilities. You can view these scores on the Medicare Care Compare tool.

Core Rating Categories

A 5-star overall score builds upon performance across three distinct areas:

  • Health Inspections: Evaluates state health surveys from the past three years, focusing on the number, severity, and scope of any safety or operational deficiencies. Only the top 10% of facilities in each state earn 5 stars in this category.
  • Staffing: Measures the average number of direct-care nursing hours provided to each resident daily (Hours Per Resident Day), alongside nurse and administrator turnover rates.
  • Quality Measures: Tracks clinical care outcomes—such as fall prevention, mobility, pressure injuries, and pain management—using standardized resident data.

How the Score is Calculated

The overall rating is not a simple average. CMS starts with the health inspection score as the baseline, then adjusts the rating up or down based on strong or poor performance in staffing and quality measures.

Why do people say to stay away from Medicare Advantage plans?

Critics and beneficiaries advise caution with Medicare Advantage plans because of restrictions on care, unexpected costs, and administrative hurdles. While these private plans often feature low or zero monthly premiums and extra perks like dental or vision, they come with significant trade-offs.

Restricted Provider Networks

  • Local limitations: Most plans use specific HMO or PPO networks, meaning you must see doctors and go to hospitals within the plan’s local area.
  • No nationwide freedom: Unlike Original Medicare, which lets you see any accepting doctor nationwide, Medicare Advantage offers very limited coverage when traveling.
  • Frequent changes: Provider lists can change annually or even during the year, meaning your favorite doctor might leave the network unexpectedly.

Prior Authorization and Denials

  • Approval delays: Private insurers often require "prior authorization" (advance permission) for specialized care, MRIs, surgeries, or rehabilitation.
  • Care obstacles: This review process can delay or block medically necessary treatments.

High Out-of-Pocket Costs

  • Cost-sharing for serious illnesses: While plans have annual out-of-pocket maximums (up to thousands of dollars), treatments like chemotherapy or expensive infusions can trigger steep 20% coinsurance charges before you reach that cap.
  • End-of-life complications: High utilization during severe or chronic illness can result in major expenses or coverage friction.

The "Medigap" Trap

  • Locked-in coverage: If you try to switch back to Original Medicare after a 12-month trial period, moving to a Medicare Supplement (Medigap) plan often requires passing medical underwriting. Pre-existing health conditions can make it difficult or impossible to qualify for a good supplement later.

What is the highest rated Medicare company?

Humana and Aetna rank as the highest-rated major national insurance companies for Medicare Advantage plans, according to evaluations by U.S. News & World Report and NerdWallet.

Because ratings depend on the specific type of Medicare coverage and your location, top-rated providers vary by category:

Medicare Advantage

  • Humana: Ranks highest for major national availability, overall plan offerings, and member experience.
  • Aetna: Earns the highest weighted average government star ratings and customer satisfaction scores from the Centers for Medicare & Medicaid Services (CMS).
  • Devoted Health: Scores very high for clinical quality and care continuity in the select states where it operates.

Medicare Supplement (Medigap)

  • State Farm: Consistently scores highest for overall customer satisfaction and low complaint rates on Medigap plans.
  • Mutual of Omaha: Highly rated for financial stability and long-standing reputation, though it often features higher premium increases.
