Dr. Michael D. Sellers in Oklahoma City: Board-Certified Cardiology with Medicare Coordination

Dr. Michael D. Sellers is a board-certified cardiologist practicing in Oklahoma City who focuses on cardiovascular evaluation and management, with established relationships for Medicare beneficiaries and established patients seeking continuity of cardiology care.

What Dr. Sellers actually is

Sellers is a physician cardiologist, not an advanced practice provider or nurse practitioner. Board certification in cardiology requires four years of medical school, at least three years of internal medicine residency, and at least three years of cardiology fellowship. His practice handles diagnostic and management aspects of heart disease, arrhythmias, hypertension, and preventive cardiology. He operates within Oklahoma City's larger cardiology ecosystem, which includes interventional and hospital-based cardiologists at major systems like OU Medicine and Integris Health, as well as private-practice cardiologists and hospitalists.

Services and referral requirements

Cardiology in Oklahoma City typically requires a referral from a primary care doctor or specialist. Most cardiologists here do not accept self-referred walk-in patients. Insurance plans, including Medicare, usually require documentation that a primary care referral exists. If you have established care with a primary care provider at a clinic or practice, that provider can initiate the referral.

Sellers' practice areas fall within general cardiology: office-based echocardiography reading, blood pressure and lipid management, evaluation of chest pain, arrhythmia assessment, and post-cardiac event follow-up. He does not perform interventional procedures (catheterization, stenting) or operate a dedicated imaging center; those services are coordinated through hospital systems. Pricing for a cardiology office visit in Oklahoma City typically ranges from $150 to $300 out-of-pocket after insurance, depending on complexity and whether testing occurs during the visit. Verify your plan's copay and deductible status with his office before your appointment.

How Sellers compares to other Oklahoma City cardiologists

Oklahoma City has at least 40 practicing cardiologists across solo practices, private groups, and health systems. The choice typically turns on referral pathway, insurance network inclusion, and whether you need interventional capability on-site.

Choose Sellers or a private-practice cardiologist if your primary care doctor has an established referral relationship with them, if you value continuity with one physician over multiple visits to a large system, and if your condition is primarily diagnostic or preventive (blood pressure titration, echo interpretation, medication adjustment). Choose a hospital-based cardiologist (at OU Medicine or Integris) if you require interventional services, if you have complex multi-system disease, or if your insurance plan features tighter integration with one system's network. Private practices often have shorter wait times for routine follow-up; systems offer on-site cath lab and advanced imaging.

Medicare is widely accepted in Oklahoma City cardiology practices, including private offices. If you carry an HMO or PPO plan, check the provider directory before scheduling, as some private practices do not contract with all insurers.

Who this practice suits and who it does not

Sellers suits patients already receiving primary care in Oklahoma City who need a cardiologist for ongoing management of stable conditions: hypertension, elevated cholesterol, history of heart attack or stent, heart failure on stable medication, or arrhythmia monitoring. If you have a referral and established relationship with a primary care team, private-practice cardiology offers focused expertise with shorter scheduling delays than system overflow.

This practice is not ideal if you are new to Oklahoma City and have no primary care referral source, if you have an acute cardiac event and require immediate hospitalization, or if you need same-day urgent cardiology evaluation (seek an emergency department instead).

What the first visit involves

When scheduling, have your insurance card available and ask whether a referral is required and whether your plan includes Sellers in-network. Arrive 15 minutes early for paper work. The first appointment is typically 45 minutes to one hour and includes a detailed cardiac history, physical exam, blood pressure and pulse measurement, and often an office electrocardiogram (EKG) or review of recent imaging if available. The cardiologist will discuss medication adjustments, testing needs (echocardiography, stress testing, advanced imaging), and follow-up intervals. Bring a list of all current medications and any prior cardiology records.

Hours, parking, and access

Most private cardiology offices in Oklahoma City operate Monday through Friday, 8:00 a.m. to 5:00 p.m., with limited or no Saturday hours. Confirm Sellers' specific office location and hours by calling ahead; practices relocate and hours shift seasonally. Parking is available at most office locations in Oklahoma City; street parking is rare and valet is not standard. Allow 20 minutes for check-in and parking before your appointment time.

Dr. Michael D. Sellers fills a role in Oklahoma City's cardiology network as a private-practice alternative to large-system referrals, serving patients with established primary care relationships and stable cardiovascular conditions.
