Basal cell carcinomas (BCCs) and squamous cell carcinomas (SCCs) are two of the most common types of skin cancer. While cancer of any kind is a concerning proposition, Mohs micrographic surgery is one of the most effective and minimally invasive treatment methods.
When it comes to skin cancer treatment, removing the entire cancerous growth — not merely the part that’s visible on the surface of the skin — is mission critical. The most important objective is that the cancerous cells are completely removed, once and for all. The secondary consideration is limiting the extent of scarring that results from the procedure. In many cases, the best way to accomplish both is through Mohs micrographic surgery.
General dermatologists across New York City refer their patients who need Mohs surgery in NYC to Wall Street Dermatology because of the expertise and outcomes delivered by Dr. Julia Tzu, who is a top-rated dermatologist in NYC who in addition to her medical school (Johns Hopkins) and dermatology residency (University of Miami), has also been dual fellowship-trained by two of the most prestigious institutions in the areas of skin cancer pathology and Mohs surgery.
Dermatologist Dr. Julia Tzu’s Perspective on Mohs Surgery
“People are often frightened by the idea of skin cancer surgery, because images of big, unsightly scars come to mind. However, my patients are usually pleasantly surprised by the inconspicuous nature of their post surgical scars due to my precise surgical technique combined by the minimally invasive nature of Mohs surgery.” – Dr. Julia Tzu, MD, FAAD
What Is Mohs Surgery?
Mohs surgery is a sophisticated out-patient procedure that removes skin cancer in stages, excising small layers of skin one step at a time, and visualizing the excised skin under the microscope, until the skin cancer is completely removed. Performed by board-certified dermatologists like Dr. Julia Tzu who have undergone official American College of Mohs Surgery (ACMS) fellowship training, it is an approach that is precise, effective, and tissue-conserving. It boasts the highest cure rate among conventional skin cancer treatments.
Mohs micrographic surgery should be performed by qualified dermatologic surgeons who are expertly fellowship-trained in the three components of the procedure:
- Cancer Tissue Removal: The surgeon must be able to surgically excise the cancerous tissue based on visual inspection.
- Lab Analysis: The office must also have an on site Mohs laboratory to prepare slides for the Mohs surgeon to interpret and analyze. This can be considered the most critical part of Mohs surgery from a medical standpoint. The slides must be analyzed correctly by the Mohs surgeon to guarantee therapeutic success.
- Reconstruction: The Mohs surgeon then closes and reconstructs (if necessary) the surgical wound to optimize cosmetic outcomes from skin cancer surgery.
This video below from the ACMS provides an overview of Mohs surgery.
How Does a Dermatologist Diagnose Skin Cancer?
Before Mohs surgery is considered as a treatment option, the first step is for a dermatologist specializing in skin cancers to diagnosis suspicious growths on the skin. While skin cancer can, in many instances, be visually diagnosed by an experienced dermatologist, a skin biopsy is the gold standard for diagnosing skin cancer and is necessary before any specific treatment can be recommended. During a skin biopsy, the skin is anesthetized by a quick injection, and a small sliver of skin is removed from the suspected skin cancer, and then sent to a laboratory for a dermatopathologist (read more on what is a dermatopathologist) to analyze under the microscope and interpret. A pathology report that contains the diagnosis is then generated based on the dermatopathologist’s findings
Mohs Surgery Outcomes
Skin cancer surgery on the face can cause much anxiety for patients because the face is an exquisitely cosmetically-sensitive area. A trained Mohs surgeon can generate excellent aesthetic outcomes on facial areas such as your nose, forehead, eyelids,and cheeks.

Choosing a Mohs Surgeon in NYC
Fortunately, New York City has some of the leading dermatologists and skin surgery centers specializing in Mohs micrographic surgery.
Factors you should consider include:
- Facility Type: Surgeries can be performed at University Hospitals like NYU (where Dr. Tzu is a part-time assistant professor). From a cost perspective, extra facility fees apply to hospital-based surgery. Surgeries can also be performed at outpatient office facilities such as Wall Street Dermatology. From a cost perspective, no facility fees apply to office-based surgery.
- Availability: Don’t delay treating skin cancer. Schedule your appointment for skin cancer surgery sooner than later.
- Credentials and Experience of the Mohs Surgeon: Dr. Tzu is fellowship-trained in dermatopathology (NYU 2010) and Mohs and reconstructive surgery (University of Pennsylvania 2011). The majority of Mohs surgeons are not board certified in dermatopathology.
- Time Allocated to Procedure: Will your dermatologist spend the extra time to ensure your skin cancer is completely removed and your cosmetic outcomes are as optimal as possible? Some medical practices performing Mohs surgeries cycle 10-20 cases per day per Mohs surgeon. At Wall Street Dermatology, we intentionally cap our Mohs surgery cases to 5 per day to give ample time for both the Mohs surgery and the reconstruction, which we believe leads to better outcomes.
The Cost of Mohs Surgery in NYC
Mohs is a highly precise but time-consuming procedure that requires iterations of excisions and analysis to deem complete cancer clearance. It also requires operation of an onsite laboratory and a Mohs technician to manage laboratory machinery and prepare slides for real-time review by the Mohs surgeon. Typical costs range between $2,500 to $6,500 per procedure for self-pay patients without insurance. The actual cost depends on the location of the surgery (hospitals and ASCs charge an extra facility fee, whereas outpatient private practices do not charge a facility fee), the number of Mohs stages or iterations required, and the type and extent of reconstruction required. For patients with insurance, the cost is generally determined by your health insurance company (and not your medical provider), but in general, will be covered by health insurance for a medically-necessary diagnosis.
Where Is Mohs Surgery Performed with Wall Street Dermatology?
Mohs surgery at Wall Street Dermatology is performed on an outpatient basis in our Financial District medical practice, which is equipped with a specialized Mohs laboratory. In addition to our existing staff, we have a highly experienced Mohs technician that assists with laboratory tissue preparation. Performed under local anesthesia, confirmed skin cancer removal is achieved within a day, and patients remain monitored in patient rooms until it is safe for them to be discharged from the office.
Dr. Julia Tzu’s Expertise as a Mohs Surgeon
Dr. Julia Tzu is double board certified, and dual fellowship trained in both dermatopathology, the study of skin tissue analysis, as well as Mohs micrographic surgery and skin reconstruction.
Her dermatopathology fellowship training was completed at New York University Hospital, a referral center for some of the most complex skin tumor diagnostic cases. This means that Dr. Tzu has the specialized training to interpret skin cancer slides with a level of expertise beyond most Mohs surgeons. Dermatopathology board certification is not required for Mohs surgeons, but is advantageous in instances where more difficult tumor recognition and diagnoses are needed.
Dr. Tzu’s fellowship training in Mohs and reconstructive surgery was completed at the Hospital of the University of Pennsylvania, a referral center for the most complex Mohs surgical cases in the Northeast. Her experience with complex surgical reconstruction allows her to perform the majority of her reconstructions in-house, without the need to refer to an outside hospital or surgical center. She is well-known for her focus on scar cosmesis and aesthetic outcomes. She is a member of the exclusive American College of Mohs Surgery, membership of which is only granted to fellowship trained, board certified dermatologists who have completed all the formal academic, institutional, and experiential requirements to meet rigorously defined standards.
Dr. Tzu is a clinical assistant professor and attending at NYU Hospital, where she teaches surgery to dermatology resident physicians on a weekly basis.
