Before You Choose a Partner

What should a private practice compare?

Ask about specialty-specific workflows, staffing, system access, reporting, transition plans, fees and termination terms. Request references relevant to your practice size.

Does verified mean HIPAA certified?

No. A verified listing means the directory reviewed business identity and profile evidence. Assess safeguards, contracts and BAA terms directly.
