Physicians’ Hidden Billing Battles: Are You Ready to Overcome Them?

Discover how a 31-provider specialty practice in Illinois transformed its revenue cycle using AI-powered RCM, RPA-enabled billing workflows, and a team of 500+ certified billing specialists delivering a meaningful reduction in denials, faster reimbursements, and measurable revenue improvement within just 60 days.

Chicago Infectious Disease, a 31-provider specialty practice in Illinois, was managing 8,000+ claims per month, but revenue was not keeping pace with clinical output. Despite strong patient volume, the practice faced delayed reimbursements, rising denials, and operational strain. Billing inefficiencies had scaled to the point where administrative workload had significantly outpaced claim throughput, impacting both cash flow and staff productivity.

The Challenge

Revenue Starts Slipping Through the Gaps

Chicago Infectious Disease was operating at a high clinical capacity, processing 8,000+ claims per month, yet the financial performance did not align with the volume of care delivered.

Before Dastify Solutions
Denial rate was consistently around 16%
AR follow-ups were delayed and inconsistent
Clean claim performance was below industry benchmarks
Internal billing teams were heavily reliant on manual workflows
Over 2,000 claims were aging toward expiration without reimbursement

The practice needed a system that could reduce revenue leakage, stabilize claim flow, and improve predictability in financial outcomes.

— Core Breakdown Areas

As a result: Denial rate reached 16%, clean claim rate was significantly impacted (falling below industry benchmarks), and revenue cycles were delayed, affecting cash flow stability.

Operationally, the burden was equally heavy. A team of 4 billing staff working 5 days a week was fully engaged in claim processing, follow-ups, and payment tracking. This translated into high AR days, slow reimbursements, and continuous revenue leakage, with AR cycles extending beyond industry norms due to manual process inefficiencies.
