About New Mexico Behavioral Health Billing

New Mexico Behavioral Health Billing provides insurance billing and administrative support exclusively for mental health practices. The focus is on managing day-to-day billing operations so providers can spend less time on administrative tasks and more time focused on their clients and practice.

The business was founded in 2021 by Corey Nellos after recognizing a growing need for reliable, specialized billing support within the behavioral health community. Through conversations with providers, it became clear many practices were leaving revenue uncollected due to time constraints, billing complexity, and inconsistent follow-up.

Corey holds an undergraduate degree in Social Work from New Mexico Highlands University and is currently working toward a Master of Business Administration. This combined background supports a practical, provider-focused approach to billing that balances operational efficiency with an understanding of the clinical environment.

New Mexico Behavioral Health Billing works with practices throughout New Mexico and across the country, utilizing TherapyNotes EMR to support accurate, organized, and consistent billing workflows.
