Case Study: CHAN Healthcare recovers millions in unpaid reimbursements and reduces revenue leakage with ACL

Chan Healthcare Auditors Business Assurance Through Targeted Data Analysis

CHAN Healthcare Auditors is a U.S.-focused internal audit firm serving more than 20 healthcare systems and working on-site across 325+ hospitals with a network of over 250 auditors. Their clients face persistent challenges around revenue capture, provisioning for bad debt, and meeting complex Medicare and regulatory requirements, making revenue leakage and compliance oversight primary concerns.

Using ACL data analysis software, CHAN performs targeted audits that quickly uncover missing charges, underpayments, and compliance issues—examples include $1M in lost cardiac charges, $625K in underpaid claims, and $480K in missed lab fees. The analytics also enable data-driven bad-debt reserves, contract modeling, sanction screening, and shared audit scripts, resulting in millions recovered, stronger controls, and more efficient, repeatable audit processes.
