Barry J. Cohen, MD in Baltimore: Medical Dermatology for Established Patients

Barry J. Cohen, MD is a board-certified dermatologist who focuses primarily on medical dermatology—treatment of skin conditions like psoriasis, eczema, acne, and rosacea rather than cosmetic procedures—and operates in the Baltimore area primarily as an established-patient practice with limited new-patient availability.

What this practice handles

Cohen specializes in medical dermatology and dermatologic surgery. His practice treats inflammatory skin conditions, infections, precancerous and cancerous lesions, and offers procedures including excision, cryotherapy, and electrocautery. He does not focus on cosmetic dermatology; patients seeking Botox, fillers, or laser skin resurfacing should look elsewhere. The practice operates at a single location and maintains a smaller patient panel, which means diagnostic time tends to be longer than at larger dermatology clinics in the region.

Insurance, new-patient status, and scheduling

The practice accepts most major insurance plans including Medicare, but new-patient appointments are difficult to obtain. As of early 2025, Cohen's schedule typically books 8 to 12 weeks out for new patients; established patients are generally accommodated within 2 to 4 weeks. There is no walk-in or same-day availability. Patients should confirm current insurance participation and copay amounts directly with the office before booking, as insurance contracts can shift. Request an appointment as soon as your primary care physician provides a referral, as the queue moves slowly.

How this practice compares to Baltimore dermatology options

Baltimore has several large dermatology practices affiliated with health systems (Sinai, Johns Hopkins) and independent practices of varying size. Practices like those in the University of Maryland Medical Center network typically handle higher patient volume and have faster appointment availability for new patients, sometimes 4 to 6 weeks. Larger practices also offer broader cosmetic services and may have fellows or residents involved in care. Cohen's practice offers the advantage of lower patient volume, which translates to more time with the provider during an office visit. If you need a routine skin check or have a condition requiring extended evaluation and discussion of treatment options over time, Cohen's smaller-scale model is more accommodating. If you need rapid access to a dermatologist or cosmetic dermatology services, a larger health-system-affiliated clinic or cosmetic specialist will serve you better.

Typical first visit

On a first visit, bring photo identification, insurance card, and a list of current medications and supplements. Allow 30 to 45 minutes. Cohen will take a full skin history, ask about family history of skin cancer and autoimmune disease, and perform a full-body skin examination. If a biopsy or minor procedure is planned, it usually occurs the same day. Patients with specific lesions or recurring rashes should photograph problem areas beforehand and note when they started and what makes them better or worse. If you are being treated by multiple specialists (rheumatology, gastroenterology), bring documentation of relevant diagnoses, since some skin conditions are manifestations of systemic disease.

Hours and location details

The practice is located in Baltimore and operates Monday through Friday, 8:30 a.m. to 4:30 p.m., with limited Wednesday afternoon availability (verification recommended, as clinical schedules shift seasonally). Parking is available at the building. The office does not hold Saturday hours. Allow time for check-in paperwork, especially on your first visit.

Who this practice suits and who it does not

This practice suits patients with chronic or complex medical skin conditions, those who have been referred by a primary care doctor or dermatopathologist, and those who value unhurried diagnostic time. It is not appropriate for cosmetic dermatology, for patients who cannot wait 8 to 12 weeks for a first appointment, or for those who prefer a higher-volume clinic with walk-in or urgent same-day access. If you have a changing mole or concern about skin cancer, Cohen's focus on dermatologic surgery and lesion management makes this a strong fit.

Cohen's selective approach to new patients and medical focus means he has maintained a reputation among Baltimore primary care physicians as a reliable specialist for diagnostic challenges and complex inflammatory conditions. For established patients, the continuity of care and unhurried evaluation model provides real value in managing long-term skin disease.
