Dr. Hector K. Collison in Baltimore: Board-Certified Cardiology in Central Maryland

Dr. Hector K. Collison is a board-certified cardiologist who practices in the Baltimore area, offering comprehensive heart disease evaluation and management to adult patients. His practice handles both preventive cardiology—screening for risk factors like high blood pressure and high cholesterol—and treatment of established conditions such as coronary artery disease, heart failure, and arrhythmias.

What the Practice Actually Is

Collison's cardiology practice operates as an outpatient specialty clinic focused on diagnostic testing and medical management rather than invasive procedures. Patients are referred by their primary care physicians, though self-referral is often possible if your insurance permits. The practice is structured to handle stable, chronic cardiac conditions; acute conditions requiring hospitalization are referred to appropriate facilities in the Baltimore region.

Services and What to Expect on the Invoice

A typical cardiology visit includes history-taking, physical examination, and often an electrocardiogram (EKG), which costs around $50 to $100 as a copay for insured patients or runs $150 to $300 uninsured. Echocardiography (heart ultrasound) carries a higher fee, usually $200 to $400 out of pocket or $50 to $150 copay depending on insurance. Stress testing runs $300 to $600 out of pocket. Holter monitoring (24-hour heart rhythm recording) typically costs $100 to $250. Office visit copays range from $30 to $60 for established patients with commercial insurance; uninsured rates vary. Verify current fees with the office, as insurance plans shift and providers adjust pricing.

How Collison Compares to Other Baltimore Cardiologists

Baltimore has several major cardiology options distributed across health systems. Specialists in the Johns Hopkins system operate at multiple sites (including Harbor Hospital and Bayview Medical Center); University of Maryland Medical Center maintains a large cardiovascular program with high procedural volume; and Sinai Hospital of Baltimore offers outpatient cardiology alongside its own cardiac catheterization lab. Private practitioners like Collison provide one-on-one continuity that larger health systems sometimes fragment. Choose a Johns Hopkins cardiologist if your diagnosis is complex or you may need catheterization and want the procedure at the same institution; choose University of Maryland if you expect frequent testing and want centralized imaging records; choose Sinai if you have ties to that system's insurance network. Choose a private practitioner like Collison if you value a stable physician relationship, shorter office wait times, and a practice focused on outpatient medical management rather than procedural volume.

Who This Fits and Who It Does Not

Collison's practice suits patients with stable heart conditions who need regular monitoring and medication adjustments: hypertension, stable angina, heart failure managed medically, and atrial fibrillation without acute decompensation. It suits those who want consistent physician continuity and those whose insurance accepts private cardiology practices. It does not suit patients needing catheterization, pacemaker insertion, or other interventional procedures; such patients will be referred to a facility-based program. It is not appropriate for acute cardiac events (go to the emergency department).

The First Visit and What to Bring

Your primary care doctor will typically send a referral with your recent blood work and a summary of your cardiac history. Bring your insurance card and a photo ID. If you have had prior cardiac testing elsewhere (EKG, echocardiogram, stress test, cardiac CT), bring those records or have them sent ahead; Collison's office may request them directly. Expect the first appointment to run 45 minutes to an hour. The doctor will review your symptoms, medications, and risk factors; perform an examination; and often order an EKG in-house. Further testing is scheduled separately. If you are uninsured, ask about cash-pay rates; many cardiology practices offer a discount for same-day payment.

Hours, Location, and Parking

Verify current office hours and location directly with the practice, as these change with network shifts. Parking is generally available at most Baltimore-area medical offices; ask whether the practice is in a dedicated medical building, a shared office plaza, or a hospital campus.

Collison's practice fills a specific niche: the outpatient cardiologist who manages the majority of Baltimore heart patients who do not require procedures, and who offers the scheduling efficiency and continuity that many larger systems cannot match.
