Peter Cheng, MD in Baltimore: Internal Medicine with Same-Day and Urgent-Care Options

Peter Cheng, MD, is an internal medicine physician in Baltimore offering scheduled primary care appointments alongside walk-in urgent evaluation for acute conditions. His practice operates within Baltimore's broader primary care ecosystem, where same-day access and insurance flexibility matter more than geographic proximity to most patients.

What Peter Cheng, MD actually is

An internal medicine practice serving adult patients who need ongoing medical management or same-day acute evaluation. The office operates as a hybrid: structured primary care appointments for chronic disease management, annual physicals, and preventive screening alongside a walk-in urgent-care function for acute illness or injury that cannot wait for a scheduled slot. This hybrid model reflects a common Baltimore approach to internal medicine, where volume and flexibility compete with appointment availability in the typical primary care network.

Services and scope

Routine services include annual physical exams, blood pressure and diabetes monitoring, medication refills, and basic preventive care. The practice accepts established and new patients. Same-day urgent walk-in visits cover acute respiratory infections, urinary tract symptoms, abdominal pain, and minor injuries. Phlebotomy is available on-site.

Pricing varies by insurance plan and visit type. Confirm your plan's in-network status and copay structure directly with the office, as rates change annually. Uninsured patients should ask about cash visit fees before being seen; most Baltimore internal medicine offices charge $150 to $300 for an initial visit and $75 to $150 for follow-ups on a cash basis.

How this practice compares to other Baltimore options

Baltimore's internal medicine market splits along access and depth lines. Large federally qualified health centers (FQHCs) like Chase Brexton Health Care and Charm City Health Center offer lower-cost or sliding-scale primary care, open to uninsured or low-income patients; appointments typically run 6 to 12 weeks out, but walk-in urgent clinics operate the same day. Private practices like Peter Cheng, MD, generally offer faster scheduled appointments (often 1 to 3 weeks) and direct physician relationships but require insurance or cash payment. Hospital systems (University of Maryland Medical Center, Mercy Medical Center) run busy primary care networks with mixed scheduling; they excel at specialist coordination and complex case management but are less convenient for routine visits. Choose a large FQHC if cost and accessibility are priorities and you have flexibility on wait time. Choose a private practice if you value appointment speed, continuity with one physician, and have insurance coverage. Choose a hospital-based practice if you need seamless access to specialists or have complicated medical history.

Who this practice suits and who it does not

Suited: established residents of Baltimore seeking a personal physician for long-term management of high blood pressure, diabetes, or cholesterol; patients with commercial or Medicare insurance; people who occasionally need same-day acute care without a multi-hour emergency room wait.

Not suited: patients requiring emergency-level stabilization (go to an ER instead); uninsured patients on tight cash budgets (seek FQHC care); patients needing next-day appointments consistently (demand may exceed walk-in slot availability on any given day).

What the first visit involves

New patients typically complete a health history intake form, either on paper or electronically beforehand. The physician conducts a full assessment, reviews medications, and may order baseline labs (lipid panel, glucose, complete blood count) if needed. The appointment usually lasts 20 to 45 minutes. Bring photo ID, insurance card, and a list of current medications and allergies. Ask whether the practice uses electronic health records (most do) and whether records can be sent to specialists or other providers.

Hours, parking, and logistics

Confirm hours directly with the office, as internal medicine practices in Baltimore often shift urgent walk-in availability seasonally or by day. Most operate Monday through Friday, 9 a.m. to 5 p.m., with some offering limited Saturday hours. Parking depends on office location within Baltimore; call ahead to confirm street parking availability or lot access.

Peter Cheng, MD's practice holds a practical place in Baltimore's primary care landscape: accessible enough for same-day urgent needs, structured enough for ongoing management, and flexible enough to fit patients with insurance and competing schedules. For residents without a regular physician, this model reduces unnecessary emergency room use while keeping appointment slots realistic.
