A dermatology consultation is a medical appointment where a skin specialist evaluates your skin, hair, and nails to diagnose conditions, screen for skin cancer, or address cosmetic concerns. A first visit typically lasts about 20 to 25 minutes and follows a predictable three-part structure: medical history review, physical examination, and a discussion of findings and treatment options.
What Happens During the Visit
Your appointment starts with a conversation. The dermatologist will ask about your family history of skin conditions, your personal history of sunburns and sun protection habits, any allergies, smoking, diet, stress, and the skin care products you currently use. If you were referred by another doctor, the dermatologist will already have some background information, along with anything you filled out on intake forms beforehand.
Next comes the physical examination. For a first visit, this is usually a full-body skin check, head to toe. You’ll have privacy to undress and change into a medical gown. The dermatologist will inspect your skin using gloved hands, covering your scalp, behind your ears, your back, and even between your toes. They won’t examine your genitals unless you raise a specific concern in that area. This baseline exam gives the doctor a picture of what’s normal for your skin so they can spot anything unusual.
Finally, the dermatologist discusses what they found and lays out a treatment plan if needed. You may get a diagnosis on the spot, or you may need to wait several days for test results before a specific condition is confirmed.
Tools the Dermatologist May Use
Beyond a visual inspection, dermatologists have a few specialized tools that help them see things the naked eye can’t. The most common is a dermatoscope, a handheld device that magnifies the skin roughly 10 times and reveals colors, patterns, and structures beneath the surface. It’s painless and non-invasive. Dermoscopy has been shown to significantly increase diagnostic accuracy for melanoma and can also help evaluate inflammatory conditions, infections, and non-pigmented lesions.
If a spot looks suspicious, the dermatologist may take a small tissue sample (a biopsy) or do a skin swab or scraping to examine under a microscope. Patch testing can identify contact allergies, and blood tests are occasionally ordered when conditions like autoimmune disorders are suspected. Photography of specific spots is also common, creating a record that lets your doctor track changes over time.
Medical vs. Cosmetic Consultations
Dermatology consultations fall into two broad categories, and the distinction matters for both the visit itself and how you’ll pay for it. A medical consultation addresses a health problem: acne, eczema, psoriasis, suspicious moles, rashes, infections, or hair loss caused by disease. These visits are diagnostic in nature and are typically covered by insurance.
A cosmetic consultation focuses on appearance rather than illness. Think fine lines, age spots, unwanted hair, or skin texture. These concerns don’t pose health risks on their own, and the treatments involved (laser procedures, chemical peels, injectable fillers) are generally not covered by insurance. Both types of consultations are performed by board-certified dermatologists, but the billing and coverage rules are completely different.
How Long the Appointment Takes
A study tracking over 600 dermatology consultations found that new patient visits had a median length of about 17 to 18 minutes, though more complex general dermatology cases averaged closer to 22 minutes. Follow-up appointments were shorter, around 15 to 16 minutes. Professional guidelines in the UK suggest allocating 20 to 25 minutes for new patients and 15 minutes for returning ones.
In practice, your total time in the office will be longer once you factor in paperwork, waiting, and any procedures done during the visit. If you’re going in for a full-body skin cancer screening with no specific complaints, the exam portion itself can be surprisingly quick, sometimes under 10 minutes, because a trained dermatologist can scan large areas of skin rapidly.
What It Costs
Cost varies widely depending on insurance, location, and the complexity of your visit. As a reference point, Kaiser Permanente’s 2025 fee schedule lists new patient office visits ranging from $125 for a straightforward, low-complexity visit up to $370 for a high-severity evaluation. Established patient visits range from $40 to $305. These are professional fees only and don’t include lab work, biopsies, or procedures performed during the appointment.
Most health insurance plans cover medical dermatology visits, but whether you need a referral from your primary care doctor depends on your plan type. HMO plans typically require a referral before you can see a specialist. PPO plans often let you book directly with a dermatologist. Medicare and Medicaid rules vary by state. Checking with your insurance before booking can save you a surprise bill.
How to Prepare
A little preparation makes the visit more productive. Arrive with a list of all medications you’re currently taking, including supplements and topical products. Remove makeup from any skin you want examined, and take off nail polish if your nails are part of the concern. If you have a specific spot that worries you, note when you first noticed it and whether it has changed in size, color, or texture.
Knowing the warning signs for skin cancer can also help you communicate clearly. Dermatologists look for growths that are new, changing, or unusual: a spot that’s getting bigger, a mole that’s changing color or texture, a sore that won’t heal within three weeks, or anything that keeps crusting, bleeding, or itching. Bringing up these details during your visit gives the dermatologist the context they need to prioritize what to examine closely.
What Happens After the Visit
Depending on your diagnosis, you might leave with a prescription for a topical cream or ointment, a recommendation for light therapy, or a plan for a minor surgical procedure like mole removal. Some conditions are managed entirely with over-the-counter products and lifestyle adjustments. Others require follow-up visits to monitor progress or adjust treatment.
If a biopsy was taken, results typically come back within a few days to two weeks. Your dermatologist’s office will contact you with results and next steps. For ongoing conditions like eczema or psoriasis, expect periodic follow-up appointments spaced weeks or months apart, with each visit running about 15 minutes. For skin cancer screening without any active concerns, most dermatologists recommend returning once a year for a routine check.
