Matthew Katz, MD in Baltimore: Medical Dermatology with Mohs Surgery On-Site

Matthew Katz, MD operates a dermatology practice in Baltimore focused on the medical and surgical treatment of skin cancer, along with general medical dermatology for conditions like eczema, psoriasis, and acne. The practice includes on-site Mohs micrographic surgery, a specialized technique that removes skin cancer layer by layer while preserving healthy tissue, eliminating the need for referrals to a separate surgical center. This setup is less common among Baltimore dermatologists and reduces the timeline and logistics burden for patients requiring skin cancer removal.

What This Practice Does

The practice handles both urgent skin cancer concerns and chronic dermatological conditions. Mohs surgery, performed in-office, is the gold standard for basal cell and squamous cell carcinomas, particularly on the face, scalp, and ears where tissue preservation matters most. General dermatology services include diagnosis and management of inflammatory skin diseases, fungal infections, hair loss, and cosmetic concerns like rosacea. The breadth means a patient can see the same provider for both a suspicious mole evaluation and follow-up treatment if cancer is found, without switching locations.

Services and What to Expect Cost-Wise

A typical first dermatology visit for evaluation runs $150 to $250 as a new-patient fee; verify current pricing when scheduling. Mohs surgery costs vary significantly by tumor size and location but generally range from $1,500 to $3,500 per case, depending on the number of layers removed and whether reconstruction is needed. Most insurance plans cover medically necessary skin cancer treatment and Mohs procedures. Cosmetic treatments (chemical peels, laser therapy for rosacea) are not insurance-covered and cost between $300 and $1,200 per session depending on area treated. Many insurance plans require a referral from a primary care physician; confirm this with your plan before scheduling.

How This Compares to Other Baltimore Dermatologists

Most dermatology practices in Baltimore refer Mohs cases to a separate surgical center, adding a wait (often 1 to 3 weeks) and requiring coordination between two locations. Having Mohs capability in-house here reduces that lag and simplifies the patient experience. For general dermatology alone, Baltimore has many options: Mercy Medical Center's dermatology department, University of Maryland Medical Center's clinic, and numerous private practices throughout the city. If your concern is purely cosmetic (Botox, fillers, laser skin resurfacing), specialized cosmetic dermatologists like those affiliated with Johns Hopkins or private aesthetic-focused practices may offer more variety in that area. If you need skin cancer diagnosis and removal in one place with fewer appointments, this practice's setup is an advantage.

Who This Suits and Who It Doesn't

This practice is ideal for patients with confirmed or suspected skin cancer, especially on the face or scalp where Mohs precision reduces scarring and recurrence risk. It also works well for anyone managing chronic skin conditions (eczema, acne, psoriasis) who wants consistent care from one provider. It suits patients with most insurance plans, though those on Medicaid should confirm acceptance. It's less suited for patients seeking extensive cosmetic work or those without insurance looking for low-cost options; the practice does not appear to offer significant discounts for uninsured patients. If your only need is a wart removal or a mole shave biopsy (not Mohs), a general practice dermatologist elsewhere may be adequate and possibly more accessible for scheduling.

What the First Visit Involves

On your first appointment, you'll complete a medical history and describe your chief complaint. If you're coming for a skin cancer concern, Dr. Katz will examine the lesion, take a biopsy if needed, and discuss findings. If biopsy results indicate cancer and Mohs is appropriate, the procedure can often be scheduled within 1 to 2 weeks. For general dermatology (acne, eczema), the visit follows a standard format: examination, diagnosis, and a treatment plan that may include topical medications, oral medications, or in-office procedures. New patients should allow 60 to 90 minutes for the first visit.

Hours, Location, and Logistics

Appointment availability changes seasonally; contact the practice directly to confirm current hours and wait times for new-patient visits. The practice is located in Baltimore and offers standard dermatology parking. Walk-in appointments are not available; all visits are by appointment only. If you require Mohs surgery, plan to spend 2 to 4 hours in the office on the day of the procedure, as the surgery and any reconstruction happen in stages.

This practice fills a real gap in Baltimore's dermatology landscape by combining skin cancer expertise with in-house surgical capability, meaningful for patients who need both diagnosis and treatment in a single location.
