Cancellation Policy

We require 24-hour notice if you need to make changes to your appointment or cancel. If you cancel less than 24-hours before appointment or no-show, you will be charged the full fee for the visit. If you need to call on the weekend to cancel for the following Monday this will be honored because we know things happen on the weekends. Surrendering your appointment in a reasonable time allows us to fill the appointment with someone waiting.

Insurance

At Greenhouse Natural Medicine, we are committed to providing the highest quality, cost-effective naturopathic care. We accept all major credit cards and Health Savings Accounts (HSAs).

Important Insurance Update

After careful consideration, effective January 1, 2026, Greenhouse Natural Medicine will no longer be in-network with the following insurance carriers:

Harvard Pilgrim (HP)

UnitedHealthcare (UHC)

Aetna

We will remain out-of-network providers with these insurers. Patients with these plans can still receive care with us—coverage and reimbursement will depend on your specific out-of-network benefits. If you have Anthem or Cigna, we continue to accept these plans in-network.

What This Means for You

  • Self-Payment at Time of Service: You’ll pay for your visit at the time of your appointment.

  • We’ll Help With Reimbursement:

    • If you have Harvard Pilgrim, UHC, or Aetna and confirmed out-of-network naturopathic coverage, we’ll submit your claim directly to your insurance. Reimbursement will be sent straight to you.

    • For all other plans, we’ll provide a superbill so you can submit for reimbursement yourself—our team will walk you through the process.

    • No Surprise Bills: You’ll always know your visit cost upfront.

    • Use Your HSA/FSA: These accounts can always be used to pay for visits.

Verify Your Coverage

Before your appointment, please contact your insurance company and confirm that “Naturopathic Services” are covered under your plan and whether you have out-of-network benefits.

Using Your Out-of-Network Benefits for Naturopathic Medicine

Many patients are surprised to learn that their health insurance may help cover naturopathic care—even when the provider is out-of-network. With a little guidance, you can make the most of these benefits and invest in the kind of holistic, personalized healthcare you’re looking for.

Step 1: Find Out if You Have Out-of-Network (OON) Coverage

The easiest way to start is by logging into your insurance portal or calling the number on the back of your card. Look for details about:

  • Out-of-network deductible – the amount you pay out of pocket before reimbursement begins.

  • Coinsurance – the percentage of each visit you’re responsible for after meeting your deductible.

  • Allowed amount – the maximum fee your plan will cover per visit.

Step 2: Call Your Insurance Company

Speaking directly with a representative is the most reliable way to understand your benefits. Please ask:

  • Do I have coverage for Naturopathic Services?

  • How much of my deductible has already been met this year?

  • What is my out-of-network deductible for naturopathic visits?

  • What percentage will be reimbursed once my deductible is met?

Step 3: Claim Submission or Request a Superbill

If you have Harvard Pilgrim, UnitedHealthcare, or Aetna and have confirmed that your plan includes out-of-network naturopathic coverage, we’ll submit the claim on your behalf. You simply pay at the time of service, and once your insurance processes the claim, reimbursement is sent directly to you.

If you carry coverage with another insurance company, we will provide you with a superbill—a detailed receipt with visit codes and fees. You’ll pay your naturopathic doctor at the time of service, then submit the superbill to your insurance company for reimbursement. Many patients find this process straightforward, and we’re here to guide you through it step by step.

Step 4: Receive Your Reimbursement

  • For Harvard Pilgrim, UnitedHealthcare, or Aetna members: Once we’ve submitted the claim on your behalf, your insurance company will process it and send reimbursement directly to you—no extra paperwork required.

  • For all other insurance plans: After you submit your superbill, your insurance company will review the claim and mail a reimbursement check.

To summarize: You pay for your visit at the time of service, and reimbursement comes straight back to you if your plan covers out-of-network naturopathic care.

Why Choose Out-of-Network Naturopathic Care?

Access the Care You Really Want

Naturopathic medicine is built on longer visits, personalized plans, and integrative therapies that don’t always fit inside conventional insurance models. Out-of-network coverage allows you to choose a provider who truly understands your health priorities.

It May Cost Less Than You Think

If you have a high-deductible plan or strong out-of-network benefits, your out-of-pocket costs can be the same—or even less—than seeing an in-network provider.

More Time, More Options, More Flexibility

Working outside the limitations of insurance billing codes means we can focus on what works best for you: longer visits, comprehensive care, and treatment plans that evolve with your needs.

Privacy and Peace of Mind

When you use out-of-network benefits, your insurance company doesn’t receive detailed information about your visits. For many patients, this added layer of privacy is invaluable.

The Bottom Line

You deserve care that’s aligned with your values and your health goals. Out-of-network benefits give you the freedom to choose a naturopathic doctor you trust, without letting insurance networks limit your options.

You can always use your Health Savings Account (HSA) or Flexible Spending Account (FSA) to pay for visits. That’s exactly what these accounts are designed for—to make holistic, out-of-pocket care more affordable. Your health is worth the investment.

Additional Fees

There are additional fees for completion of forms or letters for use outside of the patient’s medical record. This includes disability forms, letter for employment/education, FMLA forms, and year-end statements for tax purposes. Completion of forms can take-up to two weeks depending on doctor’s workload, please plan accordingly to ensure paperwork is able to be completed by your required deadlines.

Completion of disability forms, letter for employment/education, and FMLA paperwork can only be completed for patients who are currently undergoing treatment and have a scheduled follow-up appointment appropriate for the condition being treated.

Communication with Our Practitioners

We strive to promptly return calls and messages within one to two business days. Our staff answer phones and responds to emails Monday-Thursday from 8AM to 4PM. Due to high volume phone calls, emails, and other communications take time to address throughout a business day so we gently ask the following:

  • Try to limit repeat messages in a single business day. It can delay response due to increasing call/email volume.

  • Limit emails to 1-2 simple and clear questions related to current medical plan.

  • Communications requiring higher level of complexity, beyond simple questions will be referred for visit with the doctor, billed at their usual rate. If the conversation is under 10 minutes, there will be no charge for the visit.

Prescription Refill Request

  • Please contact your pharmacy to send us a refill request.

  • Allow 72 hours for doctors to complete the request.

  • Please plan accordingly based on this timeline so you will not have a gap in your medical care.

Lab Results

With patient portals becoming the norm, patients can often see their labs before the doctors. The doctors strive to have a response for the patient with non-emergent labs within five business days. These are labs related to chronic conditions which are not new onset. This represents most of our patient population.
