What is a Single-Payer Health System?

A single-payer health system is one in which a single entity, most often the government, acts as the sole insurer, collecting revenue through taxes or mandatory contributions and using those funds to cover healthcare services for all residents. Unlike multi-payer systems with competing private insurers, a single-payer approach centralizes the financing of care to reduce fragmentation and ensure broad access to essential services.

The government ensures coverage, but in most cases, care is still provided by private or independent healthcare facilities and professionals.

Purpose & Reasons for a Single-Payer Health System

• Universal Coverage: Provides every resident with access to medical care irrespective of income, employment, or prior condition.
• Financial Protection: Abolishes out-of-pocket expenses and lowers medical bankruptcies by paying for medical care through taxes,  instead of individual outlays.
• Efficiency: Merges billing and payment functions into one system, eliminating the administrative inefficiencies of multiple insurers.
• Equity: Encourages equal access to health care services without socio-economic inequalities.

Key Features of a Single-Payer Health System

• Single financing body: Government (or designated authority) serves as the payer.
• Funding source: Taxes or payroll contributions.
• Coverage scope: Essential and preventive healthcare services for the entire population.
• Provider network: Care may be delivered by public or private providers, depending on the model.
• Centralized negotiation: The payer negotiates rates with hospitals, doctors, and pharmaceutical companies, leveraging scale for cost control.

Benefits of a Single-Payer Health System

• Universal Access: Eliminates insurance gaps, ensuring no resident is left without coverage.
• Simplified Administration: Providers bill one payer, reducing billing complexity and administrative overhead.
• Cost Containment: Government leverage helps negotiate fair prices for drugs and services, lowering total system costs.
• Improved Health Outcomes: Broader access to primary and preventive care supports early intervention and better population health.
• Equity in Access: Reduces healthcare disparities tied to income, employment, or insurance status.

Challenges and Criticisms of a Single-Payer Health System

• Increased Taxes: Funding demands high public investment, commonly by way of tax hikes.
• Possible Wait Times: Centralized systems may experience waits for specialty services or elective procedures if demand outpaces supply.
• Restricted Choice: Individuals have less private insurance coverage or restricted provider choice.
• Concerns Over Innovation: Critics suggest that government control over funding will retard the acceptance of new treatments or technology.
• Political & Implementation Complexities: Moving from multi-payer to single-payer entails breaking down resistance from insurers, providers, and political stakeholders.

Examples of Single-Payer Health Systems Worldwide

• Canada - Medicare: A publicly funded, provincially administered system covering essential healthcare services. Care is delivered by private providers, and services are free at the point of use.
• United Kingdom - NHS: Fully public, with government ownership of hospitals and direct employment of medical professionals. Funded through general taxation.
• Australia - Medicare: A hybrid system where the government covers essential services, but citizens can supplement with private insurance for faster access or additional coverage.

Implications for Revenue Cycle Management

In revenue cycle management (RCM), a single-payer framework simplifies operations by consolidating all claims submission and payments through one payer. This reduces administrative burden, cuts costs linked to claim denials or mismatches, and allows providers to focus more on clinical care than paperwork. However, it also reduces payer diversity, limiting negotiation options and requiring alignment with government regulations and reimbursement rates.
