Choosing the right healthcare provider isn’t just about location or reputation; it’s about understanding their insurance participation status. The terms par provider (participating) and non-par provider (non-participating) might sound like industry jargon, but they directly influence how much you pay, what your insurance covers, and the quality of care you receive.
This is especially critical under Medicare, where the difference between participating and non-participating providers can mean hundreds of dollars in savings, or unexpected out-of-pocket costs.
In this article, we’ll unpack par vs non par providers in clear, actionable terms, compare their benefits and drawbacks, explore their role in Medicare, and give you the tools to make confident, cost-effective healthcare decisions.
What Are Participating (PAR) Providers?
A participating provider, commonly called a PAR provider, is a healthcare professional or organization that signs an agreement with Medicare to accept the Medicare-approved amount as full payment for all covered services. This is referred to as “accepting assignment.”
In practice, this means:
- The provider cannot bill the patient more than the Medicare-approved amount for covered services.
- Medicare pays the provider directly for 80% of the allowed charge.
- The patient is only responsible for any applicable deductible and/or coinsurance.
How PAR Providers Work?
When a PAR provider delivers a Medicare-covered service:
- The provider bills Medicare directly.
- Medicare reimburses 80% of the participating fee schedule amount.
- The patient pays the remaining 20% (coinsurance) plus any unmet deductible.
Example:
If the Medicare-approved amount for a service is $168, Medicare will pay the provider $134.40, and the patient will pay $33.60.
Benefits of Being a PAR Provider
- Higher Reimbursement Rates: PAR providers receive 5% higher reimbursement than non-participating providers.
- Simplified Billing: Medicare automatically processes and forwards Medigap claims to supplementary insurers, reducing administrative work.
- Better Patient Relationships: Lower out-of-pocket costs improve patient satisfaction and trust.
- Predictable Revenue: Consistent rates make financial planning easier.
- Increased Visibility: PAR providers are listed in the Medicare Participating Physicians and Suppliers Directory (MEDPARD), making it easier for patients to find them.
What Are Non-Participating (Non-PAR) Providers?
A non-participating provider, or non par provider, chooses not to sign a participation agreement with Medicare. This gives them the flexibility to decide whether to accept assignment on a claim-by-claim basis.
How Non-PAR Providers Work?
When a Non-PAR provider accepts assignment:
- They agree to accept Medicare’s approved amount for that specific service.
- Medicare pays the patient directly, and the provider collects the coinsurance from the patient.
When a Non-PAR provider does not accept assignment:
- They may charge up to the limiting charge, which is 115% of the non-participating fee schedule.
- The patient usually pays the provider in full at the time of service.
- Medicare reimburses the patient for 80% of the non-par fee schedule (not the limiting charge).
Benefits of Being a Non-PAR Provider
Greater Pricing Flexibility: Ability to set rates higher than the Medicare-approved amount (within limiting charge rules).
Potentially Higher Per-Service Revenue: For certain services, total patient payments can exceed PAR reimbursement rates.
Selective Assignment Acceptance: Decide on a claim-by-claim basis whether to accept Medicare’s rates.
Appealing to Niche Patient Groups: Flexibility may be useful for specialized care not widely available in-network.
Par vs Non Par Providers – Key Differences
Here’s a side-by-side look at the most important distinctions between participating and non-participating providers:
| Feature | Participating Provider (PAR) | Non-Participating Provider (Non-PAR) |
| Medicare Agreement | Accepts assignment for all Medicare claims | Decides per claim |
| Reimbursement Rate | 5% higher than Non-PAR | 5% lower than PAR |
| Limiting Charge | Not applicable | Up to 115% of Non-PAR fee schedule |
| Payment Flow | Medicare pays provider directly | Patient may pay provider, Medicare reimburses patient |
| Medigap Claim Processing | Automatically forwarded | Not forwarded automatically |
| Directory Listing | Included in MEDPARD | Not listed |
| Patient Costs | Lower | Potentially higher |
Cost Example – Understanding the Numbers
To make the difference between par vs non par providers crystal clear, let’s walk through an example using the Medicare service code 90792.
| Cost Element | PAR Provider | Non-PAR Provider |
| Participating Fee Schedule | $168.00 | N/A |
| Non-Par Fee Schedule | N/A | $159.60 (95% of PAR rate) |
| Limiting Charge | N/A | $183.54 (115% of Non-Par fee schedule) |
| Medicare Reimbursement | $134.40 (80% of PAR rate) paid to provider | $127.68 (80% of Non-Par rate) paid to patient |
| Patient Coinsurance | $33.60 | Varies (patient pays full amount upfront; Medicare reimburses later) |
| Potential Patient Out-of-Pocket | $33.60 | $55.86 after Medicare reimbursement |
Key Takeaways:
- PAR providers receive slightly lower total possible charges but get direct, predictable payment from Medicare.
- Non-PAR providers may receive higher patient payments but must collect from patients directly, and patients may face higher out-of-pocket costs.
Which Option is Right for Your Practice?
There’s no single right answer; it depends on your practice model, patient base, and revenue strategy.
Factors Favoring PAR Provider Status
- Predictable Revenue: Consistent Medicare-approved rates help with budgeting.
- Simplified Billing: Less paperwork thanks to Medicare’s Medigap claim forwarding.
- Patient-Friendly Costs: Attracts Medicare beneficiaries seeking lower out-of-pocket expenses.
- Directory Visibility: Being listed in MEDPARD can boost patient referrals.
Factors Favoring Non-PAR Provider Status
- Greater Pricing Control: Flexibility to charge up to the limiting charge on non-assigned claims.
- Potential Higher Earnings Per Service: Especially for certain specialized procedures.
- Selective Assignment Acceptance: Decide per claim if Medicare’s payment is acceptable.
- Niche Patient Appeal: May suit providers offering unique services not covered by Medicare.
Medicare Enrollment Rules for PAR Status
If you are enrolling as a new Medicare provider:
- You have 90 days from receiving your Provider Identification Number (PIN) to submit your PAR agreement.
- If you choose to participate after this 90-day window, you must wait for the annual open enrollment period.
- Once you choose PAR status, you must remain a participant until the next enrollment period.
Conclusion
Choosing between par vs non par providers is a strategic decision for healthcare professionals. Participating providers benefit from predictable reimbursements, simpler billing, and greater patient satisfaction due to lower costs. Non-participating providers enjoy more flexibility in setting fees but take on more administrative and collection responsibilities, and may create higher costs for patients.
By understanding how participating and non participating providers work, both in terms of reimbursement rates and patient financial impact, you can make a choice that aligns with your practice goals, business model, and patient care philosophy.
FAQs
Q1: Do patients pay more with Non-PAR providers?
Yes, in many cases. Non-PAR providers can bill up to 115% of the non-PAR fee schedule, so patient out-of-pocket expenses may be higher.
Q2: Can a Non-PAR provider still accept an assignment?
Yes. Non-PAR providers can choose to accept assignment on a claim-by-claim basis.
Q3: Is switching between PAR and Non-PAR easy?
Not mid-year. You generally must wait for the annual open enrollment period unless you are a new provider within your 90-day grace period.
Q4: Does Non-PAR mean out-of-network for Medicare?
No. Non-PAR providers are still enrolled in Medicare—they just haven’t agreed to accept Medicare’s approved payment for all services.
