Ronald B Prussick, MD FRCPC in Baltimore: Medical Dermatology with Board Certification and Mohs Surgery Expertise
Ronald B Prussick is a board-certified dermatologist in Baltimore who specializes in medical dermatology and Mohs micrographic surgery, a precision technique for treating skin cancer with the highest cure rates and the most tissue preservation.
What He Actually Treats
Prussick's practice focuses on medical dermatology—conditions like eczema, psoriasis, rosacea, acne, and skin infections—rather than cosmetic procedures. His additional FRCPC (Fellow of the Royal College of Physicians of Canada) credential reflects specialty training beyond standard US dermatology certification. Mohs surgery, his procedural focus, removes skin cancer layer by layer under the microscope, allowing the surgeon to see tumor margins in real time. This method results in cure rates of 99% for basal cell carcinoma and 95% for squamous cell carcinoma, compared to 85-90% for traditional excision, and preserves the most healthy tissue. For patients with skin cancers on the face, ears, or other cosmetically or functionally sensitive areas, this distinction matters significantly.
How It Compares to Other Baltimore Dermatologists
Baltimore has several large dermatology groups, including offices affiliated with University of Maryland Medical Center and Johns Hopkins Medicine, where dermatologists see high patient volumes and may have shorter appointment slots. Prussick's practice appears smaller-scale, which typically means longer appointment windows but potentially fewer walk-in slots and longer wait times for new patients. Dermatologists in larger health systems offer integrated electronic records and referral pathways to other specialists; independent or small-practice dermatologists like Prussick may require separate chart coordination. If you have a skin cancer in a high-visibility area or need Mohs surgery, the technical advantage of a surgeon specifically trained and experienced in the procedure outweighs system size. For routine medical dermatology (acne, rashes, inflammatory conditions), large-group dermatologists may accommodate faster scheduling. If Mohs is not your need, confirm whether the practice offers the specific treatment—such as biologic injections for psoriasis or prescription-strength eczema care—your condition requires.
Appointment Lead Times and Insurance
Dermatology appointment wait times in Baltimore vary widely. New-patient appointments at major health systems often book 4 to 8 weeks out; smaller practices may have longer or shorter windows depending on current caseload. To confirm current availability, contact the office directly. Prussick accepts most major insurance plans, but coverage for specific treatments—particularly biologics for autoimmune skin conditions and Mohs surgery—varies by insurer and plan. Call ahead to verify your plan covers his services, and be prepared to provide authorization numbers if your insurer requires pre-approval for Mohs or advanced therapies.
What the First Visit Involves
Medical dermatology appointments typically begin with a detailed history and visual inspection, sometimes with a hand-held dermoscope to examine moles or lesions more closely. If a biopsy is indicated, the dermatologist will anesthetize the area, take a small sample, and send it to pathology. You can expect the appointment to last 30 to 45 minutes. If you are seeing Prussick for a skin cancer, the first visit often includes discussion of whether Mohs surgery is the right option, based on tumor type, location, and size.
Hours, Location, and Parking
Specific hours and parking details for Prussick's practice should be confirmed by calling his office directly, as dermatology hours vary and parking in Baltimore neighborhoods ranges from street parking to reserved lots. Ask whether same-day urgent care is available for sudden rashes or infections, as this is rarely offered in dermatology and is typically handled by urgent care or a primary-care physician.
Why This Matters in Baltimore
Skin cancer is highly preventable with sunscreen and early detection, but when it occurs, outcome depends on the surgeon's expertise and technique. Mohs surgery requires special training and equipment, and not all dermatologists offer it. Prussick's board certification and Mohs credentials matter most when you face a basal or squamous cell carcinoma and want the option that heals with the smallest scar.
