Direct primary care software: the operating system for DPC practices

How a direct primary care practice runs

A direct primary care practice contracts with the patient. The patient pays a flat monthly membership, and the practice provides primary care without billing insurance for it.

No claims means no billing staff for primary care visits. The practice runs lean, and the membership fee has to cover the whole team.

That is the difference from concierge medicine, where a retainer usually sits on top of insurance billing.

The typical member journey has five steps.

1. Inquiry. Someone tired of waiting weeks for a visit, or on a high-deductible plan, calls to ask how the membership works.
2. Enrollment. The patient signs the membership agreement and sets up the monthly payment.
3. First visit. A full history, a medication list and records from the previous doctor.
4. Ongoing care. Visits, calls and messages included in the fee, often the same day.
5. Retention. The fee comes due again and again. A member who stops feeling cared for cancels.

Where the work goes

In a small DPC practice, the physician is often also the front desk.

• Enrollment questions. What the membership includes, what it doesn't, and how it works with a health plan or an HSA.
• Calls and messages. Included access means members use it. Every call can interrupt a visit.
• Scheduling. Same-day visits, annual physicals and follow-ups on one calendar.
• Records in. Charts from the previous doctor and outside lab results arrive by fax and have to reach the right patient.
• Notes. A lean practice can't afford an evening of charting.
• Keeping members. Reminders for physicals and follow-ups, and a rebooking for every miss.

What to look for in direct primary care software

Ask any vendor these questions.

1. Who answers when you're with a patient? A solo physician can't pick up mid-visit.
2. Can it explain your membership in your words? Price, inclusions and HSA questions come in every day.
3. Does it work without insurance billing? A DPC practice doesn't file claims.
4. Does it book straight into your chart? Or into a list someone copies over.
5. Does intake arrive before the first visit? Or as a PDF someone retypes.
6. Where do records from the previous doctor land? Filed to the patient, or in a fax tray.
7. Who reminds members and rebooks the ones who miss? Retention is revenue.
8. Will the vendor sign a BAA? Member data is health data, whether or not you bill insurance.

Direct primary care, HSAs and state law

Since 1 January 2026, enrollment in a qualifying direct primary care arrangement no longer stops someone from contributing to an HSA. Section 71308 of Public Law 119-21 added the rule, and IRS Notice 2026-5 explains it.

To qualify, the arrangement must consist solely of primary care services from primary care practitioners, and a fixed periodic fee must be the only payment for that care.

Three things are excluded from primary care services under the rule: procedures that require general anesthesia, prescription drugs other than vaccines, and laboratory services not typically done in an ambulatory primary care setting.

The fees for all of an individual's arrangements can't exceed $150 a month, or $300 for an arrangement covering more than one person. The limit is adjusted for inflation after 2026.

An arrangement that bills insurance separately for its services does not qualify.

HSA funds can also pay DPC fees. Under the notice, fees above the monthly limit can still be reimbursed from an HSA, but they disqualify the member from contributing.

State law decides whether the agreement is insurance. Florida's statute says a direct health care agreement does not constitute insurance and is not subject to the Florida Insurance Code. The agreement must state that it is not health insurance and that the provider will not file claims against the patient's plan for the services it covers.

Prospects will ask about all of this. Put the answers in your approved wording, and have a healthcare attorney review the agreement.

Where Caesar fits

Caesar is the operating system for direct primary care practices. It runs the front office a lean practice can't staff.

• The Phone Agent answers every call, 24/7, in English and Spanish. It answers membership and HSA questions from your approved wording, books into your chart, and transfers to the number you set. Forward your existing line. No number port.
• The Web Agent answers visitors on your site and books the first visit, with a deposit or card on file at booking.
• Patient Intake collects history, medications and consents before the first visit.
• The Document Inbox files records from the previous doctor and faxed lab results to the right patient.
• The AI Scribe drafts each visit note in your template.
• The SMS Agent sends confirmations, reminds members of physicals and follow-ups, and rebooks the ones who miss.

Caesar does not give medical advice, triage symptoms, prescribe or order labs. It doesn't bill insurance claims, and a DPC practice doesn't need it to.

Caesar works with the EMR you run today, including Elation, DrChrono, OptiMantra and IntakeQ and PracticeQ. A new practice can start on Caesar's own chart, from the first member.

For retainer practices that also bill insurance, see concierge medicine software. For prevention-focused programs, see longevity clinic software and the operating system for longevity medicine.

Between visits: the member app

• Wearables and health apps. Caesar's patient app syncs from Apple Health, Android Health Connect and continuous glucose monitors.
• What it tracks. Sleep, heart rate, activity, weight, blood pressure, blood oxygen and glucose, plus food logs, medication reminders and goals.

The membership keeps working between visits.
