Aged AR Recovery Case Study: $38.8M Before an EHR Sunset

The short answer: When an academic medical center set a hard six-month deadline to retire its legacy Oracle/Cerner system, Advantum Health delivered the aged AR recovery it needed, resolving all $38.8 million in outstanding accounts receivable across more than 50 departments before the cutover. Recoverable balances were collected, non-recoverable accounts were adjusted, and the remaining live receivables were migrated, so the organization carried zero stranded revenue into its new platform. It is a clear example of how disciplined revenue cycle management protects revenue during a high-risk system transition.

Client snapshot. Client: Academic Medical Center (anonymized). Legacy system: Oracle / Cerner. Scope: 50-plus departments. Timeline: 6 months.

The challenge: a hard deadline, with millions on the line

The organization had decided to sunset its legacy Oracle/Cerner platform within six months, driven by rising operating costs. The decision was sound, but it created an urgent financial problem. More than $38.8 million in receivables was still open across upward of 50 departments, and the legacy system was the only place that history lived. Once it went offline, any unresolved balance would effectively be lost, too old to refile, too fragmented to reconstruct, and invisible to the incoming platform.

For an institution operating under close government funding scrutiny, that exposure was not an option. The receivables also spanned the full range of root causes, from payer disputes and coding edits to credentialing delays and timely-filing risk, so there was no single lever to pull. Each department carried its own backlog, its own payer mix, and its own clock running down to the same hard deadline.

The solution: four workstreams, running in parallel

Advantum Health treated the sunset as a coordinated recovery campaign rather than a routine cleanup. Four workstreams ran at the same time so progress on revenue never had to wait on the system migration.

  1. Specialized recovery teams (months 1 to 5). Dedicated teams attacked the AR by root cause across every department, resolving payer disputes, clearing coding edits, and untangling credentialing delays so recoverable dollars were collected while there was still time to act. Structured denial management was central to protecting the recoverable balance.
  2. Robotic automation (months 2 to 5). Accounts past filing timelines that could not be recovered were systematically adjusted through automation, without manual review. This cleared the noise from the workload and let recovery teams focus entirely on dollars still in play.
  3. Parallel system build-out (months 1 to 5). A separate team configured all 50-plus departments, providers, and patient records in the incoming practice management system, then migrated the remaining live receivables across platforms so active balances kept moving without interruption.
  4. Record remediation (months 3 to 5). Financial records were systematically corrected and reconciled throughout the project, a critical safeguard for an organization under government funding oversight, ensuring the closing books were clean and audit-ready.

The effectiveness came from sequencing. Automating the unrecoverable balances early freed Advantum’s people to focus only on revenue worth chasing, and building the new system in parallel rather than after protected active cash flow while the legacy balance was worked down.

The results: on deadline, with zero stranded revenue

Measured at the six-month sunset, against $38.8 million in opening aged AR, Advantum Health met the deadline with every dollar accounted for and nothing left behind.

  • $38.8 million in aged AR fully resolved before the system went dark, collected, adjusted, or migrated.
  • 50-plus departments migrated into the new platform with live receivables intact.
  • 100 percent of non-recoverable accounts auto-adjusted, removing manual burden and accelerating the cleanup.
  • On time. The six-month sunset was met with zero stranded revenue.

Beyond the numbers, the engagement gave the institution a clean financial close and an audit-ready record at exactly the moment regulators were watching most closely. The legacy system went dark on schedule, and the organization carried no hidden liabilities into its new platform.
