Best Add-On Services for Concierge and Direct Primary Care Practices
The best add-on services for concierge and DPC practices are the ones that help improve patient outcomes, not just the practice.
Whole health diagnostics, longevity care, medical weight loss, hormone therapy, nutrition, and at-home sleep testing all give patients better access to the proactive care they're already paying a membership for. Better outcomes are what drive the patient retention practices you are looking for, not the other way around.
What Are Add-On Services?
Add-on services extend the care a concierge or DPC practice already provides into areas patients are asking for: preventive health, metabolic health, wellness, and chronic condition management.
For patients, this means:
Getting more of their care through one trusted practice they already know
Fewer referrals to outside providers for common needs
A more complete picture of their health, not just episodic treatment
The model can fit well for membership-based practices, where patients have already chosen to pay for greater access and a closer relationship with their clinician. The U.S. concierge medicine market was valued at $7.35 billion in 2024 and is projected to grow at a 10.3% CAGR through 2030, reflecting existing demand and future growth.
Why Add-On Services Fit the Concierge and DPC Model
Traditional primary care runs on episodic visits. Concierge and DPC models give clinicians room for continuous engagement, which benefits patients first:
Better continuity of care — patients don't fall through the cracks between specialists
Fewer care gaps — one practice can catch issues that a fragmented system might miss
More proactive health management — problems get addressed before they become urgent
Stronger clinician relationships — more touchpoints build trust over time
When patients get better, more connected care, practices see the natural result: higher patient retention that doesn't require growing appointment volume.
6 Add-On Services Worth Considering
1. Whole Health Diagnostics
Patient benefit: A more complete picture of their health, and a baseline clinicians can track over time.
Comprehensive lab testing can turn an annual physical into a detailed evaluation of metabolic health, cardiovascular risk, thyroid function, nutrient status, hormones, and other biomarkers, depending on clinical judgment.
Demand signals:
Medicare Part B lab spending hit $8.4 billion in 2024, a 5% increase over the prior year
65% of consumers want a healthcare system built around prevention rather than treatment, and 28% would pay more for personalized treatment
Why it works long-term: Diagnostics create a natural pathway into other care. A patient whose results flag metabolic concerns may benefit from nutrition counseling or a supervised weight-management program. Practices that treat diagnostics as part of an ongoing preventive strategy — not a one-off test — see patients return for interpretation, follow-up, and monitoring.
2. Cellular Longevity
Patient benefit: Earlier intervention on age-related health risks, built around their own biomarkers and goals.
Longevity care uses health history, lab data, lifestyle factors, and biomarkers to flag where a patient may benefit from acting sooner rather than waiting for a problem to emerge — a natural extension of the preventive approach concierge and DPC medicine already takes.
Demand signals:
Longevity-focused companies attracted $8.49 billion in financing across 331 deals in 2024, more than double the year before
Why it works long-term: Longevity programs are built around ongoing check-ins: establish a baseline, make changes, monitor results, revisit the plan. That structure keeps patients engaged with their care team over months and years, not just during a single visit.
3. Medical Weight Loss
Patient benefit: A structured, clinically supervised approach to a condition tied to metabolic health, cardiovascular risk, diabetes, and sleep.
Weight management touches nearly every other area of primary care, which makes it a natural fit for the comprehensive relationship concierge and DPC practices already offer patients.
Demand signals:
The U.S. weight loss market hit a historic $135 billion in 2025, driven largely by GLP-1 medications
Why it works long-term: A well-run program combines clinical evaluation, appropriate medication management, nutrition guidance, and ongoing monitoring, rather than treating weight as an isolated number. That kind of program calls for regular follow-ups, which keeps the patient relationship active.
The FDA does not approve nor review compounded products for safety, effectiveness, or quality. Medications will only be prescribed by a licensed clinician if deemed medically appropriate and to meet patient requirements after a thorough consultation. Not available in all 50 states. See our website for full details, important safety information, and applicable restrictions.
4. Hormone Therapy
Patient benefit: Relief from symptoms that disrupt sleep, mood, energy, and quality of life during major life-stage transitions.
Hormone-related concerns touch sleep, energy, mood, sexual health, and metabolic changes, so they fit naturally into a longitudinal primary-care relationship rather than a one-time referral.
Demand signals:
Why it works long-term: Treatment typically requires ongoing monitoring, which supports a longer-term relationship, and it gives practices a way to support patients through a life stage many feel unsupported in elsewhere.
5. Nutrition
Patient benefit: A structured, personalized plan instead of generic dietary advice.
Nutrition connects to nearly every other area of care. Patients working on weight management, metabolic health, or a chronic condition like diabetes or hypertension all benefit from individualized counseling rather than a one-size-fits-all handout.
Demand signals:
BLS projects 6% employment growth for dietitians and nutritionists through 2034, twice the average for all occupations
Global clinical nutrition market: $34 billion, projected to reach $51.5 billion by 2033
Why it works long-term: Nutrition strengthens every other add-on service on this list. Pairing it with weight management, longevity, or diagnostics gives patients a more complete experience and another reason to stay engaged.
6. At-Home Sleep Testing
Patient benefit: A convenient way to get evaluated for a condition that affects nearly every area of health, without an overnight lab stay.
Sleep problems touch energy, mood, metabolic function, and cardiovascular health. At-home testing lets appropriate patients get evaluated for conditions like obstructive sleep apnea from home.
Demand signals:
Why it works long-term: Sleep testing often uncovers issues tied to other conditions. A patient struggling with weight may also have undiagnosed sleep apnea. Catching both means more coordinated care instead of treating each issue separately.
Building a Complete Care Experience
The strongest add-on programs don't feel like a menu of unrelated extras. They connect to each other around the patient:
Service
What it does for the patient
Whole health diagnostics
Informs a personalized care plan
Nutrition
Supports weight management and metabolic health
At-home sleep testing
Surfaces an often-overlooked health risk
Hormone therapy
Addresses major life-stage needs
Cellular longevity
Supports proactive, long-term health management
Medical weight loss
Offers a structured plan for a widespread chronic condition
Connecting one or more of these gives patients a genuinely more complete experience, and gives the practice a coherent story instead of a scattered service list.
Give Patients More Complete Care, Without More Operational Burden
Every service on this list starts with the same goal: help patients get more of the care they need, in one place, from a practice they already trust. When that happens well, the growth follows.
Adding new clinical services in-house usually means new clinicians, prescribing workflows, licensing, labs, and technology. OpenLoop® provides the clinical infrastructure behind medical weight loss, longevity, hormone therapy, nutrition, and diagnostics, so concierge and DPC practices can give patients access to more comprehensive care without building every capability from scratch, and without the patient relationship or practice brand ever leaving the practice.
