Key Criteria for Choosing the Right Billing Partner
When evaluating these firms (or any billing partner), focus on:
- Clean claim rate & denial management: A billing partner should help you submit claims cleanly so re-work and denials are reduced.
- A/R (accounts receivable) days: The lower your days in A/R, the faster you get paid and the healthier your cash-flow.
- Specialty expertise: Some billing firms specialize in particular specialties (e.g., dermatology, surgery, mental health) which means better coding and fewer errors.
- Technology and reporting: Real-time dashboards, analytics, integrations with EHR/PM systems matter for visibility.
- Patient billing & collection experience: Especially as more of the patient cost-share burden shifts to consumers, a billing service that manages patient statements, payment plans, digital invoices is a plus (see inboxhealth’s focus on this).
- Transparency and cost model: Many outsource vendors charge a percentage of collections (typically 4–10%) or a flat per-claim/encounter fee. business.com+1
- Compliance, scalability & support: Ensure HIPAA and regulatory compliance, and check that the partner can scale with you.
