I · Mercury
The AI system for medical practices
Voice · Patient management · Billing
Mercury is the AI system a medical practice runs on: a voice agent built for practices of every kind, the patient-management system behind it, and the billing system behind that. Built by KET Digital, run in your accounts, priced per location. It is ready today. Anything custom to your practice is scoped as a build, with the license and the security itemized.
Founding-client pricing, per location: $1,500 to implement and $800 a month for practices with three or more locations. Single location: $5,000 to implement, $800 a month.
II · The leak
A patient who reaches voicemail mostly does not leave one. They hang up and call the next practice on the page. There is no report for calls that were never answered. The cost is real, and it is invisible.
If you cannot see the missed calls, you cannot price what they cost you.
III · The call
What Mercury does
Mercury's lines below are its actual script. The caller is illustrative. The alert on the right carries the same fields that reach your front desk by text and email, while the caller is still on the line.
Hear a sample call
It never gives medical advice and never interprets a symptom. It says it is a virtual assistant in its first sentence. Chest pain, breathing trouble and anything that sounds like an emergency go to 911 before anything else. Anyone who asks for a person gets one.
Try it from your own phone
A demo line for a practice that does not exist. Mercury answers it exactly as it answers a forwarded call: the recording notice first, then the intake. Pretend your lower back has hurt for three days and you want to be seen this week. If you give it your mobile, it texts you the alert your front desk would get. Demo calls are deleted within 24 hours.
Dial it from your phone. There is no form.
IV · What we build
Mercury at the front door, the patient-management system behind it, billing behind that. Built in your accounts, run by us, and started on real volume before you decide on the rest. What the platform actually works, day to day, is the five leaks below.
Multi-location practices start with three sites that span their range, run the platform on real volume for a full quarter, and roll the rest on at the same founding-client rates. Single-location practices simply start.
Built in your own accounts and run per location: scheduling, intake, records, and the billing work that gets treated visits paid — claims out, statements sent, balances followed up. Monitoring and monthly reporting included. If we part ways, everything stays with you.
An add-on to the platform. Mercury answers every line 24/7 in English, Spanish and Portuguese, matches a new or existing patient to the record, books into your scheduler and follows up by text. In the office, digital intake on a tablet we supply if you do not have one.
V · Underneath the front door
The five leaks
Mercury answers the calls you would have missed. That is the top of the system and the only part a patient ever hears. Underneath it, the platform works the leaks that never ring at all: the slot that evaporated, the plan left unfinished, the patient who quietly stopped coming, the referrer who never heard back. Every one of them is a visit that was already yours. The measure is visits per day, set with you at the start, and each pillar is scored against it.
The leak
A referral that reaches voicemail rarely calls back. Before a system records it, nobody even knows what was missed.
What the software does
Mercury answers every line in three languages and ends every call in a logged outcome. A web door lets a patient start at eleven at night. Missing insurance fields are flagged before they can become a denial.
What your desk does
Verifies each intake and clears it. Nothing reaches the record until it is cleared.
The leak
A cancelled afternoon slot evaporates. In most practices the no-show rate is not even measurable, so nobody can argue about it either way.
What the software does
Reminders before the visit, and a standing waitlist that offers the freed slot the same day. The consent packet carries the cancellation policy that makes the rule enforceable.
What your desk does
Works the waitlist the moment a slot frees, instead of discovering the hole that afternoon.
The leak
A patient who stops mid-plan leaves no event behind. The chart simply stays open, so nothing triggers a call and the loss stays invisible.
What the software does
Flags anyone falling behind their plan before they disappear: visits used against visits authorized, a script about to expire, a follow-up overdue.
What your desk does
Works the flagged list every day, in the patient's language, and logs what came of each call.
The leak
Past patients who could be contacted about their own care, and never are, because nobody ever owned re-engagement.
What the software does
Finds and sizes the pool, then runs the invitation in batches on a schedule instead of in a burst.
What your desk does
Books the responses. This is treatment communication to your own patients, inside healthcare marketing rules, with no advertising.
The leak
Referring doctors never hear back, so referrals never grow. Report-back means a person typing an email per patient per milestone, which is exactly why it never happens.
What the software does
Sends the evaluation summary and progress notes back to the referring physician automatically, drawn from the note your clinician already signed.
What your desk does
Nothing extra. The signed note is the source, and the release in your consent packet is the permission.
Adoption is not requested. It is operated.
Every step is measured from the audit log, not from what anyone says they did. Nothing in the loop depends on someone remembering, and nothing that drops stays invisible.
A platform you hand over gets ignored. A system somebody operates cannot be.
VI · The rollout
Step by step
Mercury sits underneath the practice you already run. Your number, your scheduler, your records and your team stay exactly where they are.
Which locations go first, what they run on for scheduling, records and billing, how your front desk handles a new patient, and who should be alerted. Mercury screens the same way your desk does.
We send the exact wording. One code, dialed once from your main line, about five minutes. Forwarding fires only on busy, no-answer and after-hours: during business hours Mercury only takes the call your team could not pick up, never a ring that is answered. Your main number and your voicemail stay exactly as they are.
We look up the exact codes for your line and carrier before the setup call and send them in writing.
What if I stop? Forwarding off with one code. Nothing else changes. Full answer below →
Before anything goes live, we call the line together, about ten minutes. We never skip this.
We listen to the real recordings with you over the first seven to ten days and fix the awkward spots. Then the system runs through a full quarter, which is the smallest sample that shows a billing cycle end to end.
Every caller in a spreadsheet, every recording and transcript, the pattern by hour and day, and one billing cycle end to end, reviewed with you. What the first quarter proved is yours either way. The rest of your locations roll on at the same founding-client rates.
VII · What it costs
Founding-client pricing
The patient-management and billing AI platform, priced once to implement and monthly to run. These are founding-client rates for the practices that come on now.
| What | One-time | Monthly | Covers |
|---|---|---|---|
| Multi-location practicethree locations or more | $1,500 per location | $800 per location | The platform on every location: scheduling, intake, records, and the billing work that gets treated visits paid. Monitoring and monthly reporting. Start with three locations for ninety days, then roll the rest on at the same rates. |
| Single-location practice | $5,000 | $800 | The same platform, built for one site. Same founding-client monthly rate. |
| The front dooradd-on · Mercury on the phone and at the desk | $5,000 per location | $1,200 per location | Every line answered 24/7 in English, Spanish and Portuguese, matched to the patient record, booked into your scheduler, followed up by text. In the office, digital intake on an iPad; if you do not have one, it is included in the build. The one-time fee covers the lines, the intake build and the tablet. |
We do not guarantee bookings or collected revenue. Nobody honest can. What we guarantee is narrower and checkable: every call, every recording, and the pattern by hour, from your own systems, reviewed with you.
Why per location: each site carries its own lines, systems and staff, so the price follows the footprint instead of a bundle you grow into. Why founding-client: the practices that come on now are the ones we build around, and their rate is the one they keep. Why the front door is separate: the platform runs the practice behind the desk; the front door is Mercury on the phone and on the tablet, which is a different scope of work. What is not on this table: anything custom to your practice, an integration we have not built or a workflow of your own, is scoped as a build on its own line, with the license and the security itemized.

VIII · The list
What the phone proves
On the phone, the rollout measures one thing: calls Mercury answered that would otherwise have hit voicemail. The first list lands inside the first two weeks; the report is generated from the call log, not typed by hand.
| Started | Day | Hour | Window | Lang | Reason | Caller | Number | Patient | Triage | Alerted |
|---|---|---|---|---|---|---|---|---|---|---|
| 09-02 21:14 | Tue | 21 | AFTER_HOURS | ES | BACK_PAIN | Marisol V. | (201) ••• ••38 | new | BOOKED | sms · email |
| 09-03 | Wed | 12 | BUSINESS_HOURS | EN | REFILL | D. Okafor | (973) ••• ••02 | existing | CALLBACK | sms · email |
| 09-03 | Wed | 18 | AFTER_HOURS | PT | POST_OP_QUESTION | J. Fernandes | (908) ••• ••71 | existing | CALLBACK | sms · email |
| 09-04 | Thu | 08 | AFTER_HOURS | EN | CHEST_PAIN | withheld | — | — | 911 | logged |
| 09-06 | Sat | 10 | AFTER_HOURS | ES | NEW_PATIENT | R. Castillo | (862) ••• ••15 | new | BOOKED | sms · email |
| 09-08 | Mon | 13 | BUSINESS_HOURS | EN | BILLING_QUESTION | T. Nguyen | (732) ••• ••90 | existing | CALLBACK | sms · email |
Row four is on purpose. The caller described chest pain. Mercury sent them to 911 before anything else, logged the call and booked nothing. Those calls stay in the list, marked 911, so you can see that it did.
Example pattern. Most practices are surprised by which hour is worst, and it is almost never the one they would guess. Some captured callers would have left a voicemail and been called back anyway, so the count is an upper bound, and the report says so above the number. No rate is printed below 20 calls.
IX · Fit
A good fit
Not a fit
Spending on new-patient marketing before you can answer the phone is how practices waste money. Fix the front door first.
X · Questions
Your carrier forwards calls to a KET number when your line is busy, unanswered, or outside your hours. Mercury answers in under ten seconds, announces the recording, introduces itself as a virtual assistant, detects the caller's language, and takes the intake using the questions your own front desk asks. It matches an existing patient to the record or creates a new one, books into your scheduler, and texts your desk the alert while the caller is still on the line. Anyone who asks for a person is transferred or scheduled for a callback.
Founding-client rates, per location. Practices with three or more locations: $1,500 per location to implement and $800 per location a month. A single-location practice: $5,000 to implement and $800 a month. The front door, Mercury on the phone and the in-office tablet, is an add-on at $5,000 per location one-time and $1,200 per location a month; the iPad is included in the build if you do not have one. Every fee is per location and flat. We are never paid per patient, per booking or per claim.
No. Your main number, your voicemail and your workflow stay exactly as they are. Forwarding only fires on the calls you would have missed. If you continue after the pilot, the KET number is transferred into your own account so it is yours. If you stop, forwarding is switched off with one code and nothing else changes.
Emergencies go to 911 before anything else. A question that needs a clinician's judgment gets a callback slot, not an answer; Mercury never gives medical advice and never interprets a symptom. Anyone who asks for a person is transferred or scheduled for a callback. Every one of those calls is logged and appears in your list, marked, so you can see what it did.
A 20-minute setup call, one five-minute call to your carrier with the exact wording we send you, and one joint test call. Most lines are live within days. Week one is calibration: we listen to the real recordings with you and tune the awkward spots.
Yes. Mercury says so in its first sentence, in the caller's language, and the recording notice comes before anything else. People are far more comfortable with a clearly labelled assistant that answers instantly than with a voicemail that never calls back.
Mercury runs inside your accounts under a signed business-associate agreement. Recordings, transcripts and intake data live where your records live, not with a third party. Mercury captures what the patient says for the clinician's review rather than assessing it itself, and tells every caller it is a virtual assistant in its first sentence. Everything is subject to your review under your practice's policies, and we adjust whatever your compliance officer asks.
No. Nobody honest can. What we do guarantee is printed under the price in section VII: every call, every recording, and the pattern by hour, from your own systems, reviewed with you. What you do with it is your decision.
That is a build. KET Digital scopes anything custom to your practice, an integration we have not built or a workflow of your own, on its own line, with the license and the security itemized. Mercury stays the base; the build sits on top. Request a proposal from the main site.
The engineer who built it. KET Digital is founder-led. The person on your setup call, your test call and your pilot reviews is the same person who wrote Mercury's intake logic and runs the system. Nothing is handed to an account manager.
XI · Provenance
Mercury is built and run by KET Digital, a founder-led AI software company in New Jersey. We build the system for your practice, in your accounts, and we stay to run it.
You talk to the person who built the system, on every call, for as long as you are a client. There is no junior tier to be handed to.
Phone numbers, accounts and keys are opened in your name. Vendor costs pass through at cost. If we part ways, nothing you paid for leaves with us.
One page naming every vendor the system touches, what breaks if one dies, and what it costs to switch. AI vendors change their terms. Your system should not depend on any of them.
