Frequently Asked Questions

Why did we decide to not take insurance?

Insurance companies have become overly intrusive in patient care, often hindering our ability to provide optimal care to our patients. The restrictions imposed by insurance companies can lead to substandard care, which is unacceptable to us.

To ensure that our patients receive the highest quality care and experience possible, we have made the decision to not contract with insurance companies. This allows us to focus solely on our patients’ needs without any external interference. Since implementing this decision, we have seen a significant improvement in the level of care we are able to provide to our patients. Our patients have noticed the difference and have expressed their appreciation for the level of care we are able to provide.

By choosing to forgo contracts with insurance companies, we have been able to put our patients first and provide them with the care they deserve. We believe that every patient deserves access to the best care possible, and this is something we are committed to providing.

Do you take Medicaid or Medicare?

Peds Happy Hearts, PLLC has opted out of Medicare and Medicaid programs. You cannot bill Medicare or Medicaid for services provided by Dr. Hua or Peds Happy Hearts, PLLC, nor can you receive reimbursement from these programs.

Can I still use my FSA, HSA, or insurance?

Of course! We accept FSA, HSA, and all major credit cards. If you have out-of-network benefits, we will happily provide you with a detailed statement (“superbill”) that you can submit for reimbursement.

Please note that we cannot guarantee reimbursement as it depends on your insurance plan.

Will I ever get a medical bill?

At our office, we value transparency and honesty. That’s why we always make sure that our patients are fully informed of their financial responsibility before starting a treatment. We believe that every patient deserves to know what they’re getting into, without any hidden fees or surprises. And that’s why we guarantee that you will never receive a medical bill from us after your visit. Trust us to take care of you and your health.

What is a Superbill?

Insurance companies use a document called a superbill that details the services provided to a client. Think of it as a receipt for your visit to the doctor’s office. Unlike traditional receipts, superbills contain crucial information, like diagnosis and procedure codes, required by insurance payers to reimburse you for the services after you’ve paid. These documents differ from regular medical bills since insurers use them to pay patients instead of doctors.

Many people underestimate how much of their superbills are eligible for reimbursement. That’s because superbills deal with out-of-network services, and people often mistakenly assume their insurance doesn’t cover out-of-network care.

If you have any questions, please check your out-of-network benefits and contact your insurance company.

In addition to your insurance company, third-party companies, such as or, can help with superbill reimbursement. Please note that Dr. Hua is not affiliated with any of these companies.

How available is the doctor after clinic hours?

Dr. Hua fully dedicates herself to providing the best care possible for her patients. She ensures that all her patients have access to a direct phone number and personally returns their calls and texts within 24 hours, even on the weekends.

More time with the doctor.

Dr. Hua saved my grandson's life. When we took him in for his checkup, his pediatrician thought she heard a murmur. Dr. Hua came in immediately and soon we knew he had a significant heart problem. Dr Hua stayed late and was so kind. Sure helped us navigate getting to specialists in Denver, and has been doing follow up since his surgery. She has always answered our questions and is available when we've needed. I cannot find words to thank her enough!
Caitlin Skinner

Dr. Hua has been with us since before our little one was born, and we wouldn’t change a thing in terms of our experience. She is caring, reassuring, honest, and attentive. She’s also an excellent pediatric cardiologist who discovered an additional, rare heart condition in our son that had been previously missed by specialists in Denver. We’ll stick with her forever!
