Participating and Non-Participating Providers: Explained

Optimize your Medicare billing strategy and patient satisfaction with PT-focused insights.

When it comes to operating a successful physical therapy practice, understanding your Medicare provider status is more than a regulatory detail—it can directly impact your reimbursement rates, patient satisfaction, and overall administrative workflow. One of the most critical distinctions to grasp is what is the difference between participating and non participating providers—a question that many clinicians and practice owners encounter as they navigate the complexities of health insurance and Medicare compliance.

This article will break down the difference between participating, non-participating, and opt-out providers, and how this choice affects billing, reimbursement, and patient relationships in a physical therapy setting. Whether you're a solo practitioner or managing a multi-provider clinic, understanding this landscape is key to making informed decisions that enhance both your business and patient outcomes.

What Is a Participating Provider?

A participating provider (often referred to as "PAR") is one who has signed a formal agreement with Medicare. This agreement commits the provider to:

  • Accept Medicare’s approved amount for all covered services.
  • Always accept assignment, meaning the provider agrees to the Medicare fee schedule as full payment.
  • Bill Medicare directly and not charge patients more than the allowed coinsurance and deductible amounts.

In return, Medicare typically reimburses 80% of the approved amount, and patients pay the remaining 20%—a setup that creates predictability for both provider and patient.

Benefits for Physical Therapy Practices

  • Streamlined billing processes: Submitting claims is straightforward and results in faster payments.
  • Higher patient volume: Patients seeking in-network care through Medicare directories are more likely to find and choose your clinic.
  • Lower patient financial burden: Patients owe only 20% of the approved fee, making services more accessible.

Being a participating provider can enhance a physical therapy clinic’s reputation as patient-friendly and fully integrated with the Medicare system.

What Is a Non-Participating Provider?

A non-participating provider (Non-PAR) also accepts Medicare but does not sign the formal participation agreement. Instead, these providers can choose on a case-by-case basis whether to accept Medicare’s assignment.

Key Characteristics:

  • They can charge up to 15% above the Medicare-approved amount, known as the limiting charge.
  • Medicare reimburses them at 95% of the approved amount, slightly lower than what PARs receive.
  • Patients often pay out of pocket first, then file claims for reimbursement.

This setup introduces more administrative complexity, both for providers and patients. However, it also allows for slightly higher fees and more flexibility in setting payment terms.

Why Some PT Practices Choose This

  • Higher potential revenue per service, especially in high-demand areas.
  • Greater flexibility in who and how they serve, especially if they offer premium services or specialized treatments.
  • Selective acceptance of assignment gives providers more control over their business.

While the added freedom appeals to some clinics, it’s important to balance this with the potential for reduced patient retention and increased administrative tasks.

Opt-Out Providers: A Third Category

The final category is the opt-out provider, who chooses to completely disengage from Medicare. These providers cannot bill Medicare for any services and must establish private contracts with Medicare beneficiaries.

Key Details:

  • Providers must submit an opt-out affidavit to Medicare every two years.
  • They set their own rates, outside of Medicare’s constraints.
  • Patients pay fully out-of-pocket, with no Medicare reimbursement.

For most physical therapy clinics, opting out is rare due to the large population of Medicare beneficiaries seeking rehab services. Still, for high-end boutique practices or out-of-network cash-based models, this approach may offer long-term benefits.

So, What Is the Difference Between Participating and Non Participating Providers?

This fundamental question boils down to billing, reimbursement, and patient financial responsibility:

Feature

Participating (PAR)

Non-Participating (Non-PAR)

Medicare Agreement

Signed

Not signed

Assignment Acceptance

Always

Case-by-case

Reimbursement Rate

95% of approved amount

Patient Billing

Only 20% coinsurance owed

Up to 115% of approved amount

Listing in Directories

Yes

No

Understanding this distinction helps physical therapy practices better serve their clientele, optimize financial planning, and maintain regulatory compliance.

Applying This Knowledge to Streamline Physical Therapy Operations

Now that we understand the distinctions, the next step is putting this into action in a way that supports the day-to-day workflow of a PT practice.

Key Considerations:

  1. Patient Demographics: If your practice serves a large Medicare population, participating status may result in higher volume and fewer billing headaches.
  2. Revenue Strategy: Non-participating status can boost revenue on a per-service basis but may limit patient access and introduce delays.
  3. Administrative Capacity: Larger practices with billing staff may better handle the complexities of non-PAR claims, while smaller clinics benefit from the simplicity of PAR status.
  4. Legal & Compliance Requirements: Understanding the assignment process and timely claim submissions is essential to avoid audits and penalties.
  5. Marketing and Visibility: Participating providers appear in Medicare’s public directories, helping attract new patients organically.

For most physical therapy clinics, the decision to become a PAR or Non-PAR provider isn’t just about numbers—it’s about long-term alignment with their business model and patient care philosophy.
