What is Electronic Remittance Advice (ERA)?
Definition
Electronic Remittance Advice (ERA) is the ANSI X12 835 transaction that details how a payer adjudicated claims, including paid amounts, contractual adjustments (CARC/RARC), and patient responsibility—the digital equivalent of an EOB. ERAs include payment trace numbers for EFT/check reconciliation and drive automated payment posting into the PM/EHR. Example: an ERA on a $1,000 charge may show a CO-45 write-off of $300 and PR-2 coinsurance of $100, yielding a $600 payer payment.
Why It Matters
For multi-location networks processing 50,000+ claims a month, manual ERA posting can consume 1,000+ staff hours and delay cash. Automating ERA intake and posting typically reduces posting time by 70–90% and can lower AR days by 2–4 while surfacing 1–3% underpayments that would otherwise be missed.
How Ventus AI Helps
Ventus AI agents log into payer portals and clearinghouses, retrieve ERAs/EOBs, parse 835 data, normalize CARC/RARC codes, and auto-post payments and contractual write-offs directly in your PM/EHR—without APIs. They also flag underpaid lines against contracted rates and open follow-up tasks, operating 24/7 via browser-native automation with HIPAA and SOC 2 Type II controls. At Smilist, Ventus agents already status 3,000+ claims weekly; the same no-API approach scales ERA retrieval and posting across large DSOs and health systems in under 7 days.
