Concierge medicine software: the operating system for concierge practices

How a concierge practice runs

A concierge practice sells access. The patient pays a retainer, and the practice keeps its panel small enough to keep its promises.

Most concierge practices still bill insurance for covered visits. The retainer pays for what insurance doesn't: time, availability and services outside the plan. That is the difference from direct primary care, where the membership fee is the whole payment for primary care.

The typical member journey has five steps.

1. Inquiry. A call from someone whose doctor is retiring, or who wants more time with one. Often a referral from a current member.
2. Enrollment. The practice explains the retainer, what it includes and what insurance still pays. The patient signs a membership agreement.
3. Onboarding. Records from the previous practice, a full history and medication list, and a long first visit.
4. Access. Same-day or next-day visits, longer appointments and a direct line to the practice.
5. Renewal. The retainer renews, and the member decides whether the access was worth it.

Every step is a promise about access. A call that reaches voicemail breaks it.

Where the work goes

Responsiveness is the product, and responsiveness is work.

• Answering every call. Members expect an answer, not a phone tree. After hours too.
• Explaining the membership. What the retainer covers, what insurance still pays, how renewal works. Prospects ask the same questions every week.
• Scheduling fast. Same-day requests, long annual visits and follow-ups, on a small calendar.
• Onboarding records. Charts from the previous practice arrive by fax, and every page has to reach the right patient.
• Documentation. Long visits produce long notes.
• Keeping members engaged. Annual physicals and follow-ups need reminders. A member who never comes in doesn't renew.

What to look for in concierge medicine software

Ask any vendor these questions.

1. What happens to a member's call at 9 pm? Answered, or a voicemail for tomorrow. Access is what the member pays for.
2. Can it reach your physician when you want it to? A transfer to the number you set, under the rules you set.
3. Can it explain your membership in your words? Retainer questions are most of the prospect calls.
4. Does it book straight into your EMR? Or into a list someone copies over.
5. Does intake arrive before the first visit? Or as a PDF someone retypes.
6. Where do outside records land? Filed to the patient, or in a fax tray.
7. Who reminds members about the annual physical? And who rebooks the one who misses.
8. Will the vendor sign a BAA? Member data is health data.

Retainer fees and Medicare

Federal guidance limits what a retainer can buy from a Medicare patient.

A participating physician may charge Medicare patients for items and services Medicare does not cover. The HHS Office of Inspector General said so in a 2004 alert on added charges for covered services.

A fee that only lets a patient obtain Medicare-covered services is different. The OIG calls an "access fee" or "administrative fee" of that kind double billing.

In one case the OIG describes, a physician paid $107,000 to resolve potential liability for charging patients, including Medicare beneficiaries, an annual fee.

The retainer agreement should say exactly what the fee buys. Have a healthcare attorney review it.

The new HSA rule for direct primary care doesn't cover a retainer on top of insurance billing. Under IRS Notice 2026-5, an arrangement that charges a fixed periodic fee but bills separately for its services, through insurance or otherwise, is not a direct primary care service arrangement.

Where Caesar fits

Caesar is the operating system for concierge practices. It runs the access your members pay for, around your chart.

• The Phone Agent answers every call, 24/7, in English and Spanish. It answers membership questions from your approved wording, books into your EMR, 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 enrollment 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 practice and faxed lab results to the right patient.
• The AI Scribe drafts the note for long visits 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 bill insurance claims. Clinical questions go to your physician under the rules you set.

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.

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.

Your physician sees the month, not just the visit.
