athenahealth is best for ambulatory groups that run scheduling, documentation, and billing in athenaOne. Notable is best for organizations, often health systems, that want AI agents on the EHR they already have. To automate your payer operations and work every denial, start with the Substrate Claim Status Agent.

Also consider Substrate
Substrate ARC is an agentic denial and reconciliation platform for provider groups, hospitals, and health systems. Substrate combines all your systems and data sources across clearinghouses, payer portals, EMRs, lockboxes and more, to comprehensively support your billing team and enable you to work every single denial. Consider Substrate if:
- You need end-to-end denial management, from triage through remediation, and appeal filing, not just phone dispositions
- Your payer mix is portal-heavy (Medicare, Medicaid MCOs, specialty commercial)
- You want structured PM writeback and audit trails across status, appeals, and posting
- You prefer agentic automation over manual execution or offshoring and outsourcing (Substrate is listed in the Anthropic Connector Directory and publishes a public claim-status MCP.)
- You want to keep billing in house but make it fast and cost effective
