Peter Stamas, MD in Baltimore: Internal Medicine with Same-Day Urgent Visits

Peter Stamas, MD operates a solo internal medicine practice in Baltimore that accepts walk-in patients for acute visits alongside scheduled appointments for preventive and chronic disease management. Unlike large multi-specialty medical groups, the practice operates as a single-physician clinic, meaning continuity of care depends on one provider's availability rather than a rotation among specialists.

What the practice actually is

Stamas practices general internal medicine, the field concerned with diagnosis and management of non-surgical adult diseases, from diabetes and hypertension to respiratory infections and thyroid disorders. His practice handles both new and established patients, seeing them for initial comprehensive exams, ongoing management of chronic conditions, preventive care, and acute illness. The clinic does not provide urgent care as a separate service line; rather, same-day slots exist for acute problems within a schedule also devoted to routine appointments. This structure differs from dedicated urgent care centers, which are designed for high-volume triage and typically do not establish long-term patient relationships.

Services and typical visit structure

The practice offers standard internal medicine services: initial comprehensive physical exams, management of common chronic diseases (hypertension, diabetes, hyperlipidemia, asthma, COPD), preventive screenings aligned with age and risk, prescription medication management, and evaluation of acute illness. Patients with complex multi-system disease or those requiring coordination across specialties may be referred to specialists, but the practice itself does not provide specialized procedures such as endoscopy or advanced cardiac testing.

Pricing is not publicly posted on practice materials; confirm costs with the office directly, as internal medicine visit fees in Baltimore typically range from $150 to $300 for a new-patient comprehensive exam and $75 to $150 for follow-up visits, though insurance coverage and copayments vary widely by plan. The practice accepts most major insurances; verify coverage before scheduling.

Same-day acute visit slots are available for patients with established relationships but not typically for completely new patients seeking urgent evaluation of an acute problem. Patients with chest pain, shortness of breath, or other potential emergencies should go to an emergency department rather than attempt a same-day office visit.

How this practice compares locally

Baltimore's internal medicine landscape includes large health systems such as Johns Hopkins Medicine and University of Maryland Medical Center, in which primary care physicians practice alongside specialists and diagnostic facilities. Stamas' solo practice offers focused, individualized attention and consistent one-provider care, an advantage for patients who value continuity. The trade-off is that complex problems or emergencies cannot be managed within the practice; referral out is necessary.

For patients seeking a Baltimore-based internist within a larger system, Johns Hopkins Community Physicians operates multiple primary care clinics throughout the city, including several with same-day or next-day urgent slots. University of Maryland Medical Center's primary care network operates similarly. Both systems offer the advantage of on-site imaging, laboratory, and specialist referral, but wait times for non-acute appointments may be longer, and continuity may be interrupted by provider schedules.

For acute problems that do not warrant emergency care, dedicated urgent care chains such as CareFirst Urgent Care have multiple Baltimore locations and are designed for walk-in evaluation; they typically have short wait times but do not establish ongoing relationships. A solo practice is most useful for patients who have an existing relationship with the provider or who prioritize consistent care from one physician.

Who this practice suits and does not suit

The practice is well-suited to Baltimore adults with one or two stable chronic conditions (hypertension, diabetes) who want consistent primary care and occasional acute visit access through the same provider. Patients new to the Baltimore area and seeking an internist may find it suitable if they are comfortable calling ahead to book appointments rather than expecting walk-in availability for new patients.

The practice is not ideal for patients with complex multi-system disease, frequent acute exacerbations, or those who require rapid access to advanced diagnostic tools. Uninsured or underinsured patients should confirm coverage directly with the office before scheduling, as pricing and payment options are not advertised.

First-visit process

New patients should call the office to schedule a comprehensive initial appointment, which typically lasts 45 to 60 minutes and includes a full medical history, physical exam, and review of current medications. Bring insurance information and a list of current medications or pharmacy contact information. The provider will order baseline laboratory tests (lipid panel, glucose, thyroid function) if indicated by age and history. Follow-up appointments are usually scheduled at that first visit.

Hours, location, and logistics

Confirm current hours and exact address by calling the office directly. Parking availability and public transit access depend on the clinic's location; ask the office staff about these logistics when you call to schedule. Most Baltimore internists operate Monday through Friday during standard business hours, with limited or no weekend availability.

Stamas' solo practice model offers a rare combination in today's Baltimore health care landscape: a single internist maintaining a focused practice without hospital affiliation or assembly-line scheduling. For patients who value consistency and want a primary care provider who knows their history, the practice fills that gap effectively.
