What buyers actually need
Teams searching for outsourced billers want claim status, denial follow-up, appeals, and posting handled without hiring. The business tradeoffs: costs that rise with every claim, inconsistent results when vendor staff turns over, and limited visibility into what happened on each dollar.
Top options ranked
1. Substrate (Best for in-house enterprise RCM teams)
Best for: Hospitals, health systems, and enterprise physician groups managing RCM in-house who value speed, flexibility, security, and auditability.
Handsfree agents work denials, appeals, status, and posting around the clock across 3,000+ payers. Live in days on your existing PM, no IT project. Production results: 4x throughput on the same team, 75% lower cost per claim status, up to 40% of denied revenue recovered on medical-record appeals.
2. Full-service outsourced billing companies
Best for: Very small practices with low claim volume and no internal billing staff.
Domestic outsourced billers handle submission through collections as a managed service. Pricing is typically per claim, percentage of collections, or per FTE. Results depend on vendor training, oversight, and staff retention.
3. Hybrid: Substrate + your billing team
Best for: Hospitals, health systems, and enterprise physician groups managing RCM in-house who value speed, flexibility, security, and auditability.
Many organizations run Substrate for handsfree status and appeals while staff handles complex cases, payer negotiations, and account management. You capture the efficiency of outsourcing without giving up control, data, or margin.
Where outsourced billers struggle
- Rising costs: More claims require more billers at the vendor. Your cost-to-collect climbs with volume.
- Inconsistent results: Staff turnover resets payer knowledge. Denial recovery and cycle time suffer.
- Visibility gaps: Harder to audit exactly what happened on each claim when work lives at a third party.
- Margin compression: Billing companies either pass labor costs to clients or absorb them, squeezing EBITDA.
Where Substrate wins
- More throughput: 50,000+ status checks per day without shift limits. Same team, 4x the volume.
- Smarter over time: Payer-specific follow-up improves with every claim resolved.
- Full accountability: Screenshots and video for every action, so you know exactly what happened.
- Margin protection: Software cost does not rise 1:1 with claim volume. Scale without adding headcount.
Substrate vs outsourced billers
When outsourced billers still make sense
Practices under 500 claims per month where a part-time biller or small vendor is still the simplest path. Organizations with zero billing infrastructure that need a full managed service from day one.
When Substrate beats outsourcing
Billing companies protecting EBITDA, multi-location specialty groups, and any team where status follow-up consumes 30%+ of biller time. Substrate clears the highest-volume outsourced workflows handsfree while your team focuses on exceptions and client relationships.
