The Silent Revenue Drain: How Interventional Radiology Practices Lose Money Without a Single Unpaid Claim 

Interventional radiology practices tend to think about billing risk in terms of denials — claims that come back rejected, authorizations that weren’t obtained, and documentation that didn’t support the procedure billed. These are real problems. But they are visible problems. Someone catches them, works them, or writes them off. The loss has a face. 

The more dangerous revenue loss in IR billing looks nothing like a denial. It looks like a payment. It gets posted, the month closes, and no one asks whether the reimbursement was correct, competitive, or recoverable. After months of this, the underperforming rate becomes the baseline. The payer’s failure to update its fee schedule becomes an expected denial reason. The 60-day processing delay becomes “just how that insurer works.” None of it triggers an alert. All of it compounds. 

Over more than 20 years of working with interventional radiology and other specialty practices across New York, New Jersey, California, and beyond, we have observed the same erosion pattern with striking consistency: IR practices don’t lose revenue in one event — they lose it incrementally, through underpayments that get normalized before anyone measures them. The three situations below are not separate billing issues. They are three expressions of the same underlying dynamic, and they are happening in IR practices right now.
