About Master Billing LLC

The team behind your

Founded by dermatology RCM operators who saw firsthand what practices were leaving on the table — and built the infrastructure to fix it.

“We built Master Billing because dermatology practices deserve a billing partner that understands their work as well as they do.”
— Rohan Doodnauth, Partner & Advisor

Most billing vendors serve dozens of specialties and spread their expertise thin. Master Billing was built differently — founded by operators who understood the billing complexity of dermatology and built the infrastructure to solve it.

Every workflow, every coder, and every payer rule is optimized for dermatology from day one. We operate as a true extension of your practice — not a vendor you manage, but a partner invested in your long-term revenue health.

Leadership

specialize in derm.
