Yellowstone Dermatology Associates

Yellowstone Dermatology Associates is a dermatology practice led by board-certified dermatologist and Mohs surgeon Eric Maranda, MD, FAAD. The business operates three locations in Montana and Wyoming, offering medical, surgical, and Mohs surgery services to treat conditions like skin cancer, acne, eczema, and psoriasis. They emphasize personalized, compassionate care and are committed to serving veterans and underserved communities.

The practice offers Mohs surgery, which is described as the most effective technique for treating skin cancer by removing cancerous tissue in thin layers while preserving healthy skin. This procedure is commonly used for basal cell carcinoma, squamous cell carcinoma, and melanoma, boasting a nearly 100% cure rate and a single office visit completion time.

Patients can schedule appointments at three convenient locations: Billings, MT at 178 S 32nd St W Suite 2; Cody, WY at 720 Lindsay Ln Suite B; and Sheridan, WY at 1274 N Main St. The Cody and Sheridan sites operate from 9:00am to 3:00pm on Saturdays, while the Billings site accepts Saturday appointments by request only.

To get started, patients must call (406) 702-1323 or use the online booking system to schedule an appointment, as the clinic does not accept walk-ins. For the first visit, patients are advised to bring a valid photo ID, insurance card(s), and any previous skin biopsy results.

The clinic provides a range of treatments including cryotherapy, excision, scraping, burning, radiation therapy, and topical medications for skin cancer. They also offer diagnostic testing for fungal infections and manage conditions such as contact dermatitis and vitiligo alongside standard acne and eczema treatments.

The team includes Dr. Eric L. Maranda, who holds a Dermatology Research Fellowship from the University of Miami, and Nicole Will, PA-C, a board-certified Physician Assistant who joined in January 2026. Nicole earned her Master's from Rocky Mountain College and participated in the AHEC Scholars Program to improve rural care access.

The practice accepts new patients and highlights its commitment to serving veterans daily. They also mention a patient portal for teledermatology access and provide resources for making payments and checking insurance acceptance.

For surgery procedures, patients are generally able to drive afterward, but those undergoing Mohs surgery are recommended to have someone assist them due to potential facial bandages impairing driving ability.

The clinic operates on a schedule where Saturday appointments are available at Cody and Sheridan locations from 9:00am to 3:00pm, while the Billings location operates Monday through Friday from 8:00am to 5:00pm with Saturday appointments by appointment only.

The clinic states it does not accept walk-ins and requires patients to call or book online. For urgent same-day appointments, patients are instructed to call (406) 702-1323 and provide details about their medical condition.

The clinic defines an out-of-network provider as one outside the insurance company's network, where reimbursement occurs at a negotiated rate and financial responsibility may be higher. They recommend contacting insurance in advance to understand coverage.

The clinic offers Saturday consultations and treatment discussions to accommodate working individuals, noting that many find it challenging to seek medical care during weekdays.

The clinic provides a variety of treatment options for skin cancer, including traditional surgery, topical medications, scraping, burning, freezing, radiation therapy, and Mohs micrographic surgery, with experts evaluating conditions to determine the best option.

The clinic treats basal cell carcinoma, noting that early diagnosis leads to high recovery chances, and lists cryotherapy, excision, and Mohs surgery as treatment options for this common skin cancer.
