How Lister Reduced Accounts Receivable by 38% Through End-to-End Billing Optimization

Background

A multi-provider healthcare center was struggling with growing Accounts Receivable (AR), delayed claim submissions, unresolved denials, and inconsistent follow-up on unpaid claims. The existing billing workflow lacked timely coordination between the providers and billing team, resulting in slower cash flow and increasing outstanding balances. Lister assumed responsibility for the complete end-to-end Revenue Cycle Management Starting early 2025, while also helping the client resolve outstanding claims from prior periods.

Challenges

The practice faced several operational and revenue cycle challenges:

  • Claims were submitted with a standard 3-day lag after the Date of Service, delaying reimbursements.
  • Provider signatures and coding clarifications were pending, preventing timely claim submission.
  • Denials were not consistently worked or appealed within appropriate timelines.
  • Unpaid and no-response insurance accounts received minimal follow-up.
  • Historical AR accumulated due to unresolved claims dating back to June 2023.
  • Limited payer portal access slowed claim status verification and denial resolution.
  • High Closing AR, Insurance AR, and 90+ day AR negatively impacted cash flow.

Lister's Solution

After conducting a comprehensive assessment of the billing workflow, Lister implemented several process improvements.
