Glossary of Cash-Pay and Direct Primary Care Terms Every Patient Should Know

When you start researching affordable healthcare outside the traditional insurance system, you run into a lot of overlapping terms fast. Direct primary care, concierge medicine, retainer medicine, cash-pay, direct-pay, health-sharing ministry, and catastrophic plan all describe different things, but they get mixed together in articles, ads, and even doctor websites. That confusion can make it hard to compare options or know what questions to ask.

This glossary gives you plain definitions for the terms you are most likely to see. It is not medical advice, and it does not tell you which option is right for you. It is a reference you can return to any time a term stops you cold. Where a term has a formal definition from a government or professional body, we link to that source so you can read the primary material yourself.

Direct primary care (DPC) is a practice model in which a primary care doctor charges patients a flat periodic fee, usually monthly, in exchange for a defined set of primary care services. The practice does not bill insurance for those covered services. The American Academy of Family Physicians (AAFP) describes DPC as a model that removes third-party billing from the primary care relationship, which lets doctors spend more time with fewer patients. Because DPC membership is not insurance, patients typically still need a separate insurance policy or another arrangement to cover hospitalizations, specialist visits, and other care outside the DPC scope. Membership fees vary by practice and patient age, so always ask a specific practice for its current fee schedule.

Concierge medicine is a membership-based model that shares some features with DPC but has important differences. Many concierge practices charge a retainer fee and also bill your insurance for individual visits on top of that fee. Some concierge practices do not bill insurance at all and operate more like DPC. The term is not standardized, so you need to ask any concierge practice exactly how it handles insurance billing and what the retainer covers. Retainer medicine is the broader umbrella term for any practice that charges a periodic fee for enhanced access or a defined set of services, whether or not it also bills insurance. You may see all three terms used interchangeably, which is why asking specific questions matters more than relying on the label alone.

Cash-pay and direct-pay are often used interchangeably to describe paying a healthcare provider directly, without submitting a claim to insurance. A cash-pay price is the amount a provider charges when no insurer is involved. Some providers post these prices publicly; others share them on request. Paying cash can sometimes cost less than using insurance, especially if you have a high deductible, because you skip the insurer's processing layer. However, cash payments generally do not count toward your insurance deductible unless your plan specifically allows it, so check your plan documents or call your insurer to confirm.

A high-deductible health plan (HDHP) is a specific type of insurance plan defined by the IRS. For 2024, the IRS set the minimum deductible at $1,600 for self-only coverage and $3,200 for family coverage. HDHPs are relevant to the direct-pay world because many people pair an HDHP with a DPC membership: the DPC membership covers routine primary care at a predictable monthly cost, while the HDHP provides a safety net for large or unexpected expenses. The IRS also allows people enrolled in an HDHP to contribute to a Health Savings Account (HSA), a tax-advantaged account for qualified medical expenses. Whether DPC membership fees are a qualified HSA expense is a nuanced tax question; the IRS has not issued a definitive ruling that covers all DPC arrangements, so consult a tax professional before using HSA funds for DPC fees.

A health-sharing ministry (also called a healthcare sharing ministry or HCSM) is an organization whose members share each other's medical costs according to the ministry's guidelines. Health-sharing ministries are not insurance and are not regulated as insurance under state insurance laws. The Centers for Medicare and Medicaid Services (CMS) notes that health-sharing ministry membership does not satisfy the Affordable Care Act's minimum essential coverage standard, though the individual mandate penalty was reduced to zero at the federal level starting in 2019. Members agree to share costs voluntarily, and the ministry is not legally obligated to pay any claim. Before joining, read the ministry's guidelines carefully to understand what costs are and are not eligible for sharing.

A catastrophic health plan is a real insurance product, not a cost-sharing arrangement. Under the ACA, catastrophic plans are available to people under 30 or those who qualify for a hardship or affordability exemption. These plans have low monthly premiums but very high deductibles, meaning you pay most routine costs out of pocket until you hit the deductible. HealthCare.gov explains that catastrophic plans must cover three primary care visits per year before the deductible and must include ACA-required preventive services at no cost. Some people pair a catastrophic plan with a DPC membership to keep monthly costs low while maintaining protection against major medical events.

Fee-for-service (FFS) is the traditional insurance billing model in which a provider charges a separate fee for each service delivered and submits a claim to the insurer. The insurer pays its portion and the patient pays the rest. DPC practices explicitly step away from this model for primary care services covered by the membership. Understanding FFS helps you see why DPC doctors often describe their model as freeing them from paperwork: they bill one flat fee to the patient rather than coding and submitting dozens of individual claims.

Price transparency refers to a provider's practice of publicly posting or readily sharing the prices patients will pay before care is delivered. Federal rules require hospitals to post standard charges, and the No Surprises Act created protections against unexpected out-of-network bills in certain situations. For cash-pay and DPC providers, price transparency often means listing membership fees, visit costs, and common procedure prices on their website or in a welcome packet. When a provider is transparent about pricing, you can compare costs before you commit, which is a core principle behind directories like DirectMedicine.

A Federally Qualified Health Center (FQHC) is a community-based clinic that receives federal funding under the Health Center Program administered by the Health Resources and Services Administration (HRSA). FQHCs serve patients regardless of ability to pay and use a sliding-fee scale based on income. They are not direct-pay or DPC practices, but they are an important part of the affordable-care landscape and worth knowing about if cost is a primary concern. You can find HRSA-funded health centers using the health center finder on the HRSA website.

Telehealth refers to healthcare services delivered remotely using video, phone, or secure messaging. Many DPC and cash-pay practices include telehealth as part of their membership or offer it at a flat per-visit fee. Telehealth is a delivery method, not a payment model, so it can exist inside or outside insurance billing. When a DPC practice offers telehealth, it typically means you can message or video-call your doctor without an extra charge, which is one of the access benefits members often cite. Always confirm with a specific practice what telehealth services are included and whether any visits require an additional fee.

DirectMedicine is a directory built around price transparency and plain information. When you search for a direct primary care doctor, a cash-pay specialist, or a concierge practice, the listings show you what each provider offers and, where practices have shared their pricing, what you can expect to pay. You are not guessing or waiting for a bill. You are comparing real options with real information before you make a call.

The glossary terms above come up throughout the site, in provider profiles, in filters, and in educational articles. Knowing what DPC, cash-pay, retainer, and HDHP mean lets you use those filters with confidence and ask better questions when you contact a practice. DirectMedicine does not sell insurance, does not recommend specific providers, and does not give medical advice. Its job is to make the search for transparent, direct-pay care easier so you can make the decision that fits your health and your budget.
