Common questions about membership, insurance, Medicare, hospitalization, and how Sereno Medicine works.

Your first visit is a comprehensive intake — not a rushed meet-and-greet. Plan for 60 to 90 minutes. Dr. Lopez will review your full medical history, current medications, past records, and family history. He will conduct a physical examination and discuss your health goals, concerns, and anything you have been meaning to ask a doctor but never had the time.
Before your visit, our team will request records from your previous providers and any recent lab work so that nothing is duplicated and nothing is missed. You will leave your first appointment with a clear picture of where your health stands, what needs attention, and a plan for getting there.
No. This is not health insurance and does not replace your insurance. Your membership covers your primary care — the relationship with your physician, office visits, direct access, care coordination, and everything listed in the Membership section. You should maintain your health insurance for hospitalization, emergency care, specialist visits, imaging, lab testing and prescription coverage.
Think of it this way: insurance covers catastrophic and specialty care. Your Sereno membership covers the physician who actually knows you and manages the rest.
Yes. If you are enrolled in Medicare Part B, your membership fee covers the concierge access services — same-day appointments, direct physician access, extended visit times, and all the enhanced access benefits of membership. Clinical services such as office visits, wellness exams, and chronic disease management are billed directly to Medicare. You remain responsible for any applicable Medicare deductibles, copayments, and coinsurance.
No portion of your membership fee is applied toward or credited against any Medicare-covered service. The two are kept completely separate.
Absolutely. When specialist care is needed, Dr. Lopez manages the referral, communicates with the specialist, transfers relevant records, and follows up to make sure nothing falls through the cracks. You are never left to navigate the system on your own.
Specialist visits are billed through your insurance — they are not included in your Sereno membership. But the coordination, advocacy, and follow-up are.
At Methodist Hospitals, Dr. Lopez serves as your attending physician — managing your care directly, coordinating with specialists, reviewing treatment decisions, and overseeing your discharge and transition home. He is personally available for hospitalized members the large majority of the year. During planned absences, Complete Care Medical Associates — a trusted hospital-based physician group he works closely with — provides coverage with his direct involvement.
At non-Methodist facilities, Dr. Lopez has limited access to your hospital records and resources. He will communicate with the attending physicians to the extent possible, but cannot manage your care with the same level of involvement. For this reason, when hospitalization is anticipated and clinically appropriate, we coordinate admission at Methodist whenever possible.
You may cancel at any time after the initial 6 months with written notice. Your membership remains active for 30 days after cancellation, so there is no gap in your care. During that time, we will provide referral letters to other providers and transfer your medical records promptly. Any prepaid fees are refunded on a prorated basis.
There are no long-term contracts and no cancellation penalties.
For true medical emergencies, call 911 or go to the nearest emergency room — always. Your membership does not cover emergency department services.
For urgent but non-emergency concerns after hours, Dr. Lopez is available 24/7 the large majority of the year. During planned absences, a qualified, board-certified colleague will be available. You will always have someone to call.
No. Sereno Medicine is not a 501(c)(3) nonprofit, and membership fees are not tax-deductible as charitable contributions. This is intentional. Nonprofit status comes with bureaucratic oversight and restrictions that can compromise a physician's ability to make independent clinical decisions. We chose to remain a private practice so that every decision — clinical, operational, and financial — is made with one priority: the patient in front of us.
Our Sereno Sponsors Program and our commitment to below-market pricing exist because we believe in them, not because a tax code requires it.
Concierge fees in San Antonio vary considerably across practices. Sereno Medicine starts at $125 per month — deliberately positioned below the typical local concierge rate. There are no enrollment fees, no cancellation penalties after the initial six months, and no surprise charges.
Members who choose to contribute above the $125 floor fund sponsored memberships for patients in financial hardship through the Sereno Sponsors Program. The full pricing structure is on our pricing page.
Concierge medicine and direct primary care are closely related but not identical. Both involve a monthly membership paid directly to the physician, and both reduce the patient panel so that the physician has the time required for unhurried care. The differences are largely operational: pure direct primary care practices typically do not bill insurance at all, while concierge practices generally continue to bill insurance for clinical services.
Sereno Medicine operates as a hybrid — membership covers concierge access services, while clinical visits may be billed through insurance or Medicare depending on each member's coverage.
The IRS treats concierge membership fees inconsistently. The portion attributable to specific qualifying medical care is generally HSA- and FSA-eligible; the portion attributable to access services and administrative benefits generally is not. Because the rules are unsettled and your tax situation is individual, consult your tax advisor or HSA administrator before using these accounts toward membership fees.
We are happy to provide an itemized invoice for any portion of services that qualifies.
Time. The average primary care physician in the United States manages a panel of more than 2,000 patients and spends about 12 minutes per visit. That math does not allow for careful diagnosis, thoughtful preventive planning, or unhurried conversation.
By limiting the practice to a deliberately small panel, Dr. Lopez protects the time required to practice medicine the way it should be practiced. Quality of attention is structurally guaranteed, not earnestly hoped for.
Same-day or next-day for established members in nearly all cases. Visits last as long as the conversation requires, not a fixed slot length.
Direct physician access by phone, secure message, and email means many concerns are resolved without needing an in-person visit at all.
No. Sereno Medicine is an internal medicine practice, which means we care for adults only. Our family add-on covers dependents ages 17 to 26 — typically older teenagers and young adults transitioning out of pediatric care.
For pediatric care, we are happy to recommend trusted pediatricians in San Antonio.
Sereno Medicine is located at 8122 Datapoint Drive, Suite 1110, in the South Texas Medical Center area of San Antonio.
Members come from across San Antonio and the surrounding area, including Stone Oak, Alamo Heights, Olmos Park, Terrell Hills, The Dominion, Shavano Park, Hill Country Village, Boerne, Fair Oaks Ranch, and Helotes. For members who cannot come to the office, home visits are included in membership.
