When Your Patient Is in the Hospital: Privileges, Hospitalists and Coordinating Care
Most primary care physicians no longer round. Hospitalists now run much of general inpatient medicine, and the handoff between hospital and office is where information gets lost. For a concierge physician, a member’s hospital stay is the moment the membership is most visible and hardest to deliver. This brief looks at what the evidence says about a primary physician staying involved and what hospital rules generally allow, then turns both into a playbook for the week a member is admitted.
New in October 2026. Built on Medicare outcome studies, CMS billing guidance and national handoff guidance, all opened and checked this month.
Start here: the questions this brief answers
Tap a question for the short answer, then jump to the evidence.
Hospitalists now provide much of the inpatient care primary physicians once gave. In Medicare data, the share of older inpatients visited by a primary care physician who had seen them before admission fell from 44.3% in 1996 to 31.9% in 2006. Observational studies link primary physician involvement with somewhat better results after discharge, but none is a trial, and physicians who still round may differ from those who stopped. The best-documented gap is at discharge: summaries arrive late or incomplete, and early follow-up helps high-risk patients most. For a concierge physician, the practical question is less about keeping full admitting privileges and more about a dependable system: learning of admissions fast, reaching the hospitalist, getting the discharge information and seeing the member within days. Hospital bylaws decide what role you may play inside the building, so start with the medical staff office.
Do I still need admitting privileges?
Not necessarily. Many hospitals offer a staff category that lets a community physician refer a patient and keep visiting while a hospitalist attends. Each hospital’s bylaws define what every category may do, so the answer is local.
Go to the full answer ↓Does it help patients when their own physician stays involved?
Possibly. In one large Medicare study, patients cared for by their primary care physician had lower adjusted 30-day mortality (8.6% vs. 10.8%) and went home more often than hospitalist patients. The studies are observational, so they cannot prove cause.
Go to the full answer ↓Where does care most often break down?
At discharge. A systematic review found direct physician-to-physician communication in only 3% to 20% of discharges, and a discharge summary at the first follow-up visit in 12% to 34%.
Go to the full answer ↓Can I bill Medicare for the work after discharge?
If your practice bills Medicare, the transitional care management codes 99495 and 99496 may apply. They require contact within 2 business days and a visit within 7 or 14 days. Have counsel check how this fits your membership agreement.
Go to the full answer ↓What should my membership agreement promise?
Only what you can deliver at every hospital your members use. Part 4 compares the roles a hospital may allow, and Part 5 gives a playbook you can adapt.
Go to the full answer ↓The hospital stopped being the primary physician’s second office
A generation ago, most internists started the day on hospital rounds. That routine is largely gone. Medicare claims show the change happening fast: from 1997 through 2006, the odds that a hospitalized older patient was cared for by a hospitalist rose 29.2% a year, and in some regions more than 70% of that care came from hospitalists by 2006.1
The same research group then asked what happened to continuity. Fewer older patients were seen in the hospital by a physician who knew them from the office.2
Growth has not stopped. The Society of Hospital Medicine’s 2025 survey covered nearly 11,000 full-time-equivalent physician hospitalists, the largest group it has ever reported on, and 64% of hospitalist groups expected to add staff in the coming year.4 Practice Insight
Lee Goldman, who named the role with Robert Wachter, has said continuity was an early worry and that the answer is “passing the baton” between inpatient and outpatient physicians who see themselves as one team.3 That framing matters for concierge physicians. The hospitalist is not a rival for the patient. The hospitalist is the colleague who holds the baton for a few days.
A member is admitted at 2 a.m. to a hospital 30 minutes from your office, where you hold no privileges. Write down what you can actually do in the next 24 hours, then compare it with what your membership materials say you will do. The gap between those two lists is where trust is won or lost.
What the outcome studies show, and what they cannot
Two large Medicare studies compared patients cared for by their own primary care physician with patients cared for by hospitalists. Both point the same way. Neither settles the question.
The larger one followed 560,651 Medicare beneficiaries admitted in 2013 for 20 common medical conditions. Hospitalists cared for 60% of them, primary care physicians for 14% and other generalists for 26%.5 The earlier study, from the University of Texas Medical Branch group, found that hospitalist patients had shorter stays and lower hospital charges but used more care in the month after discharge.6
Kuo and Goodwin also put dollar figures on the trade. Hospitalist stays were 0.64 days shorter and hospital charges $282 lower, but Medicare costs in the 30 days after discharge ran $332 higher, which the authors called a cost shift.6 Population Data In the 2013 data, other generalists had the longest stays and more readmissions, which suggests the difference is not simply hospitalist against everyone else.5 Population Data
Both studies use administrative Medicare claims. Primary care physicians who still admit their own patients chose to, and the patients they admit may differ in ways claims data do not capture. Hospitalists also bring real advantages, starting with being in the building all day. No randomized trial has tested whether a primary physician’s presence changes outcomes, and no study CMT found looks at concierge physicians specifically.
CMT’s reading is narrower than a headline would be. The evidence fits the idea that knowing the patient helps most at the edges of the stay: deciding where the patient goes next, and what happens in the weeks after. That is also where a concierge physician can contribute without attending. This is editorial reasoning from observational data, not a proven effect.
Discharge is where the handoff breaks
If one finding in this field is consistent, it is that information does not travel well from the hospital to the office. A JAMA systematic review found that the discharge summary was often late and often missing the details the next physician needed.8
| Finding | What the source reports | What it means for a concierge practice | Evidence type |
|---|---|---|---|
| Hospital and office rarely talk directly | Direct communication between hospital physicians and primary care physicians in 3% to 20% of cases; a discharge summary available at the first postdischarge visit in 12% to 34%, and in 51% to 77% at four weeks8 | Do not wait for the summary to arrive. Ask for it, and call the discharging physician | Clinical Trial Evidence |
| Summaries leave things out | Diagnostic test results missing from 33% to 63% of summaries, with pending tests and follow-up plans also often left out8 | Track pending results yourself until each one is resolved | Clinical Trial Evidence |
| Early follow-up matters most for high-risk patients | In 65,085 North Carolina Medicaid discharges, a visit within 7 days was linked to meaningfully fewer readmissions for patients with multiple chronic conditions, about 24% of discharges; the authors concluded most patients do not meaningfully benefit from early follow-up9 | Sort discharged members by risk. See the sickest within a week | Population Data |
| Transitional care services track with better results | Among Medicare beneficiaries, TCM services were billed after 3.1% of eligible discharges in 2013 and 7.0% in 2015; adjusted mortality 31 to 60 days after discharge was 1.0% with TCM vs. 1.6% without, and costs were $3,033 vs. $3,35810 | A structured 30-day plan is worth building, whether or not you bill for it | Population Data |
| Structured discharge programs exist | AHRQ’s Re-Engineered Discharge toolkit includes medication reconciliation, sending the summary to the outpatient clinician, follow-up calls and a help line; AHRQ reports that research showed it reduced readmissions and emergency visits11 | Borrow the outpatient half of the model for your own protocol | Policy and Law |
The Medicare transitional care management (TCM) codes put a clock on this work. The timeline below follows the CMS booklet; it describes billing requirements, not a clinical standard.12 Policy and Law
The member goes home from an inpatient hospital or another qualifying setting, such as a skilled nursing facility. The 30-day TCM period starts on the discharge date.
Clinical staff make interactive contact with the patient or caregiver, about more than scheduling. Phone and email both count. Two or more documented, timely attempts can count if they are unsuccessful.
Medication reconciliation and management are done on or before the date of the face-to-face visit.
Face-to-face visit for high-complexity medical decision making (99496).
Face-to-face visit for moderate-complexity medical decision making (99495).
The period ends. Only one physician or nonphysician practitioner may report TCM for the patient in that period.
TCM matters only to concierge practices that still bill Medicare, the blended model in CMT’s framework.13 A practice that has opted out does not submit Medicare claims. For a practice that does bill, one question needs counsel: if the membership agreement says post-discharge visits are included in the fee, and the practice also bills Medicare for them, the arrangement may run into the federal warning against charging Medicare patients for covered services.12,
What you promise vs. what the hospital allows
A membership brochure can say “your doctor will be there.” The hospital’s medical staff bylaws decide what “there” means. Federal rules require every participating hospital’s bylaws to state the duties and privileges of each category of medical staff and the criteria for granting privileges to individual practitioners.15 Policy and Law
So the menu below is general. Category names, rights and fees differ from one hospital to the next.
Attending with full privileges
You admit the patient and write the orders as physician of record. This is the most direct role and the most demanding: you meet the staff’s credentialing criteria and carry the daily responsibility for the patient, wherever your office schedule stands.15 Policy and Law
It fits a concierge physician with a small panel, one main hospital and the time to round.
Refer and follow, or a similar category
Some hospitals offer a category that lets a physician refer a patient for admission while a hospitalist or specialist takes over admitting duties. The referring physician may visit and provide follow-up care but does not make the inpatient decisions, and must still show current competence.16 Practice Insight
Hospitals use it partly to keep ties with community physicians who no longer admit. Ask whether it includes chart access.
No appointment: a visit as the patient’s physician
Without a staff category you generally cannot write orders or document in the chart, though you can still talk with the team. HIPAA treats consulting another provider about a patient as treatment, which does not require the patient’s written authorization.17 Policy and Law
Hospital policy still governs record access and unit visits. Confirm it before you promise members bedside visits.
Coordination from outside
Some concierge companies describe this role openly. MDVIP says its affiliated physicians may check on patients at the hospital, call them or talk with relatives, and asks members to say when they are admitted because the doctor may not know automatically.18 A PartnerMD physician writes that privileges are now “few and far between” for primary care and describes calling hospital doctors to “quarterback” care.19 Industry Research
A six-society consensus statement on transitions, including the Society of Hospital Medicine and the American College of Physicians, asks clinicians to respect the “hub of coordination of care” and says patients should always know who is responsible for their care and how to reach that person.20 Practice Insight During a stay, that person is the attending. Before and after it, a concierge physician is well placed to be the hub.
Promise what you can deliver at every hospital your members use, on your worst week. Verbs you control, such as call, coordinate, update the family and see you within days of discharge, travel better than “we manage your hospital care.” Before you sign or revise a membership agreement, ask each hospital’s medical staff office what your category allows and have counsel review the wording. This is CMT’s editorial view, not a legal standard.
A hospitalization playbook for your practice
The Joint Commission’s alert on handoffs cites an estimate that communication failures played a part in 30% of malpractice claims, and lists the minimum a receiving clinician needs: the sender’s contact information, illness severity, a patient summary, a to-do list, contingency plans, allergies, code status, medications, and dated labs and vital signs.21 Practice Insight Most of that sits in a concierge physician’s chart already. The playbook below turns it into a routine. Check what is true for your practice today.

Know the hospital’s rules
Ask each medical staff office what your category allows before you describe hospital care to members.
Make the handoff routine
A one-page summary, a call to the hospitalist, contact within two business days and a visit within the week, done the same way every time.
Be the constant
The hospital team changes every few days. You do not. Members should know you are the one who stays.
How this brief was built
CMT searched for peer-reviewed studies of the shift from primary care physicians to hospitalists and of outcomes by type of inpatient physician, then for evidence on discharge communication and early follow-up. Several journal and database pages blocked automated access during research; for those studies CMT relied on the published abstract or a university or society summary and says so in the reference (“Summary via”). Billing rules come from the CMS Medicare Learning Network booklet on transitional care management (August 2025). Handoff guidance comes from The Joint Commission’s 2017 alert and AHRQ’s discharge toolkit. A six-society consensus statement adds principles for transitions. Hospital staff rules are described only in general terms from the federal condition of participation and a credentialing trade publication, because bylaws differ by hospital. Practice examples come from two concierge company websites and are labeled Industry Research. CMT’s own books are cited only for the model framework, because CMT could not confirm that they address hospital care in detail. Every source was opened in October 2026.
No study CMT found reports outcomes for concierge members specifically. The outcome studies describe primary care physicians in general, mostly in Medicare, and are labeled as such. No direct primary care (DPC) data appear in this brief, and no combined concierge and DPC figures are used. The Kripalani review is labeled by its design, a systematic review, even though most studies it pooled were observational. The playbook in Part 5 is a CMT editorial aid, not a clinical, legal or billing standard.
How to read the evidence types
Every key finding is labeled by evidence type. Labels describe the type of evidence, not its value. Each type answers different questions. Funding is disclosed on every source.
Randomized trials and systematic reviews.Best for cause and effect.
Large observational studies and government data.Best for trends at scale.
Surveys, smaller studies and expert consensus.Best for real-world experience.
Company-sponsored or company-reported data that is not peer-reviewed.Best for early signals and operating data.
Statutes, regulation and official guidance.Best for what is required.
What we don't know
- How many concierge physicians still hold hospital privileges, and in which staff categories. No public dataset tracks this.
- Whether hospital visits by a non-attending concierge physician change outcomes. The published comparisons look at who attends, not who visits.
- Outcomes after hospitalization for concierge members compared with similar patients in conventional practices.
- How often hospitals notify community physicians of admissions in practice, and how quickly.
- Whether newer, team-based hospitalist models have narrowed the post-discharge gaps found in the 2007 to 2017 studies.
