Quick answer: AKASA and Waystar solve different layers. AKASA is mid-cycle AI for coding, CDI, and denial operations in health systems. Waystar is a clearinghouse and payments platform with AltitudeAI for denial prevention on 837/835 traffic. Neither replaces the other. Keep Waystar for submission if you already route there. Choose AKASA only if the program is documentation and mid-cycle ops, not claims routing.
Inclusion criteria: Head-to-head on deployment model, EHR fit, payer coverage, and whether you must replace a clearinghouse or BPO.
Honest limitations: Substrate does not replace a clearinghouse, EHR, coder, or patient-billing platform. It automates post-submission AR. Claim status includes denial root-cause analysis (eligibility, records, medical necessity, wrong route), not just a 277 code or an 835 variance. Clinical edge cases still go to staff. Coding, CDI, and patient-facing billing are out of scope.

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
