San Antonio Telemedicine Doctors for Integrative Functional Medicine

Direct Integrative Care, led by Yoon Hang Kim, MD, MPH, is a membership-based telemedicine practice offering integrative functional medicine to San Antonio residents. This guide explains how to evaluate, verify, and select a telemedicine provider for root-cause care, detailing the specific questions to ask, the costs involved, and the clinical workflow you can expect from a consultative practice.

How to Choose a Provider

Choosing a functional medicine provider requires looking beyond marketing language. A high-quality practice prioritizes depth over volume. In a standard high-volume clinic, a physician may see 30 to 40 patients a day, leaving 10 to 15 minutes per visit. This is often insufficient for complex, multi-system conditions. A consultative model, such as the one used by Direct Integrative Care, caps the number of active clients to ensure each individual receives sustained attention.

Depth of History Taking

Functional medicine is a root-cause approach. It requires a detailed investigation of genetics, environment, nutrition, and stress physiology. If a provider cannot dedicate 60 to 90 minutes to your initial evaluation, they are likely not practicing true functional medicine. They are likely practicing symptom management.

Continuity of Care

Complex illness does not wait for your next scheduled appointment. You need a provider who is accessible between visits. Look for practices that offer secure messaging, phone calls, and telemedicine appointments as standard features of the membership. This continuity allows for real-time interpretation of lab results and fine-tuning of treatment plans.

Questions to Ask Before Committing

Before signing a membership agreement, you must clarify the scope of the relationship. Ask these specific questions to ensure the provider fits your needs.

• Is this a primary care relationship? Most functional medicine practices are consultative. They work alongside your primary care physician (PCP). Confirm that the provider expects you to maintain a PCP for acute illness, immunizations, and emergency care.
• What is the communication protocol? Ask how quickly you can reach the physician. Is it 24/7, or is it business hours? Does the membership include direct access to the doctor, or only to a nurse or assistant?
• What tests are included? Clarify if lab fees are part of the membership or billed separately. In many direct care models, the membership covers the physician's time, while labs and medications are billed to your insurance or paid out-of-pocket.
• What is the cancellation policy? Understand the terms if you need to leave the practice. A reputable practice will have a clear, fair exit process.

Verifying Credentials and Claims

The functional medicine space is unregulated in many ways. Anyone can call themselves a functional medicine doctor. You must verify credentials independently.

Board Certification

Check if the physician is board-certified in a relevant field, such as Preventive Medicine, Family Medicine, or Internal Medicine. You can verify this through the American Board of Medical Specialties (ABMS) or the relevant specialty board. For example, Yoon Hang Kim, MD, MPH, holds board certification in Preventive Medicine.

The Clinical Workflow

Understanding the process helps set realistic expectations. The workflow in a telemedicine functional medicine practice typically follows these steps.

1. Initial Consultation: A 60 to 90-minute video visit. The physician takes a comprehensive history, including medical, family, social, and environmental factors.
2. Diagnostic Testing: The physician orders advanced labs. These may include inflammation markers, hormonal panels, gut health tests, and nutrient levels. You complete these at a local lab.
3. Plan Development: The physician reviews the results and creates a personalized plan. This may include nutrition changes, targeted supplementation, stress management techniques, and medication adjustments.
4. Follow-Up and Monitoring: Regular video visits to track progress. You can message the physician between visits with questions or concerns.

This process is iterative. It is not a one-time fix. It is a partnership focused on long-term health transformation.

Understanding Membership Costs

Direct care and functional medicine memberships vary in price. The cost is driven by the level of access and the complexity of the case.

Note that membership fees do not cover labs, imaging, or medications. You should maintain separate health insurance for these services. The membership is a direct agreement for physician consultation services, not a substitute for health insurance.

Common Mistakes to Avoid

Patients often make errors that hinder their progress. Avoid these common pitfalls.

Expecting a Cure

Functional medicine addresses root causes. It does not promise a cure for all conditions, especially chronic autoimmune or neurodegenerative diseases. Realistic expectations are essential. The goal is management, improvement, and quality of life, not necessarily a complete reversal of disease.

Abandoning Primary Care

Do not cancel your primary care physician. The functional medicine provider works alongside your PCP. Your PCP is responsible for acute care, emergencies, and preventive screenings. The functional medicine provider focuses on chronic, complex issues.

Ignoring Lifestyle Factors

Supplements and medications are tools. They are not magic. If you do not address sleep, stress, and nutrition, the clinical interventions will have limited effect. The physician will guide you, but you must do the work.

Telemedicine vs. In-Person Care

Telemedicine offers distinct advantages for functional medicine. For patients with conditions like ME/CFS, Long COVID, or severe fibromyalgia, travel to a clinic is physically taxing. Virtual consultations remove this barrier. The core of functional medicine is conversation and reasoning. This translates well to video. While physical exams are important, the diagnostic work rests heavily on history and lab results, which can be reviewed remotely.

In-person care is still necessary for certain procedures, imaging, and hands-on treatments. A hybrid approach, where you see a local PCP for physical needs and a telemedicine specialist for complex chronic care, is often the most effective model.

Care for Complex Conditions

Some conditions benefit more from a root-cause approach than others. Dr. Kim specializes in complex, multi-system illnesses that often puzzle conventional doctors.

• Autoimmune Conditions: Including Hashimoto's thyroiditis and rheumatoid arthritis. Low-dose naltrexone (LDN) is a key therapy in this area.
• Mast Cell Activation Syndrome (MCAS): A complex condition involving histamine and inflammatory mediators.
• Chronic Fatigue and Fibromyalgia: Conditions where standard tests often come back normal.
• Mold Toxicity: Environmental illness that requires a specific diagnostic and treatment protocol.

If you have one of these conditions, a provider with specific experience in that area is crucial. Generalists may not have the depth of knowledge required to manage these complex cases.

Legal and Clinical Protections

Understanding the legal and clinical boundaries protects both you and the provider.

Scope of Practice

Telemedicine-only practices do not perform physical exams, procedures, or injections. All care is delivered via secure video or telephone. You must be physically located in a state where the physician holds an active medical license at the time of each consultation.

Not an Emergency Service

This practice does not provide emergency or urgent care. If you are experiencing a medical emergency, call 911 or go to your nearest emergency department. The membership is for chronic, non-urgent conditions.

Consultative, Not Primary Care

The practice is a consultative integrative and functional medicine practice. It does not replace your primary care physician. Members are expected to maintain an established relationship with a PCP who is responsible for acute illness, preventive screening, and overall care coordination.

San Antonio and Regional Access

Direct Integrative Care serves patients in Texas, including San Antonio, Houston, Austin, and Dallas-Fort Worth. The practice also serves patients in Iowa, Illinois, Missouri, Georgia, and Florida. This wide reach allows patients in rural or underserved areas to access specialized care without traveling long distances. For San Antonio residents, this means you can consult with a specialist from the convenience of your home, office, or car, eliminating the need for travel and waiting rooms.

Timing Your Consultation

When should you seek functional medicine care? If you have been cycling through specialists for years without relief, it is time. If your standard tests are normal but you do not feel well, it is time. If you have a complex, multi-system condition that is not being managed effectively, it is time. Early intervention can prevent further deterioration. However, do not wait until you are in crisis. Functional medicine is a long-term process. It takes time to identify root causes and implement changes. Starting early gives you the best chance of success.

Long-Term Outcomes

What can you expect over time? Results are not immediate. It takes weeks to months to see significant improvements. The initial phase focuses on diagnosis and stabilization. The middle phase focuses on implementing lifestyle changes and targeted therapies. The long-term phase focuses on maintenance and optimization. Many patients report improvements in energy, pain, and cognitive function within 3 to 6 months. However, individual results vary. The key is consistency and partnership with your provider. You are the central actor in your own recovery. The physician's role is to guide you, not to do the work for you.

Key Takeaways

• Choose a provider who prioritizes depth over volume. Look for a capped client list and extended visit times.
• Verify credentials independently. Check board certification and specific functional medicine training.
• Understand the cost structure. Membership fees cover physician time, not labs or medications.
• Maintain your primary care physician. Functional medicine is consultative, not a replacement for PCP.
• Set realistic expectations. The goal is management and improvement, not a guaranteed cure.
• Telemedicine is effective for functional medicine. It removes travel barriers for patients with chronic fatigue.
• Start early. The sooner you address root causes, the better your long-term outcomes.
• Be an active participant. You must do the lifestyle work. The physician provides the roadmap.
