That gap between billed and collected is where behavioral health margins quietly erode, and most operators can’t see it until the revenue is already gone. In a recent Dazos panel, operators reported that roughly 30% of treatment days went unreimbursed before they had claim-level visibility. This article explains why the gap exists and what closes it. ## **What Does “Billed Isn’t Collected” Mean In Practice?** Billing a claim and collecting on it are two different events, often separated by weeks and several failure points. A day of care gets billed, but it can be denied, underpaid, or rejected on a technicality. If nobody catches the problem before the insurer’s timely-filing deadline, the revenue is gone permanently. Sam Hessler described running a manual review across five or six locations with about 300 clients in care and finding roughly 30% slippage: nearly a third of treatment days provided but never reimbursed. Louis Devaleix added the uncomfortable premise underneath it. No billing company is perfect, so something always slips, whether you bill in-house or outsource. ## **Why Do Clean Claims Still Get Denied?** Most preventable denials trace back to a few unglamorous causes. Mike Colasuonno, CEO of Providence Health Group, identified two at his organization: coordination-of-benefits (COB) records that weren’t kept current, and incorrect authorization-of-representation (AOR) forms. For certain payers’ plans, staff frequently completed only the home-state form when both the home-state and local forms were required. He invested in billing intelligence software and hired one full-time person to keep COB records updated and audit AOR forms, and says it cut denials by about 60%. These are process gaps that stay invisible without claim-level visibility. ## **Why Won’t An Outside Biller Chase Every Dollar?** The economics explain a lot. Louis Devaleix pointed out that a billing company charging 4-5% of collections earns very little on a small or out-of-state claim, so those claims often aren’t worth their time to pursue. A patient who travels out of state might have 25 of 30 days pay at one rate while the other 5 default to the home state, and those 5 claims are rounding error to the biller. For the provider, a handful of missed high-value days can decide whether a month is profitable. The provider and the biller don’t share the same incentive on small claims, which is why the provider needs independent visibility. ## **How Does Daily Claim Visibility Recover The Money?** Timing decides the outcome. When you can see a denial or a medical-records request in near-real time, you can resolve it while the patient is still in your care, instead of tracking down a discharged patient months later or missing the timely-filing window entirely. Mike said working flagged claims this way recovered $937,000 in one year, money that the prior year had gone uncollected because it aged out of timely filing. George Mavrookas, CEO of Agape, found close to $350,000 within roughly his first 45 days using the same billing intelligence tools, including Aetna claims that weren’t being repriced correctly and claims stuck on pending COBs. ## **What Happens To The Billing Relationship Over Time?** Counterintuitively, the amount of recovered revenue tends to shrink after the first year, which is a good sign. Sam Hessler explained that flagged-claim volume trends down as billers learn their work is being checked and raise their standards. Mike said he fact-checks his billing company’s AR reports consistently and is right about 99% of the time. He credits that to knowing his own data cold, and adds that his billing company is a good one. Visibility turns billing from a black box into a managed function. ## **From CPA To ROI: Finding The Patients You’re Built To Help** The same visibility reframes marketing and admissions. For years the guiding metric was cost per acquisition. CPA tells you what a patient costs to acquire, but it says nothing about whether that patient fits the care you provide, or what they are worth across a full stay. Fit is where good clinical care and revenue line up. Mike Colasuonno’s facilities make about 70% of revenue in the back half of care, once deductibles and coinsurance are met. A patient who gets oversold to land the admission often leaves AMA early, which costs the facility money and leaves the person without the treatment they came for. When the match is right, patients stay and do better, and the economics follow. So Mike judges his marketing and referral partners the same way, right down to individual call-center reps, on the revenue and the quality of the patients they bring in rather than raw admission counts. A campaign with a higher CPA can be the better investment when it sends people who fit the program and stay through treatment. ## **Where To Start** Start where Mike did. Get a clear look at your own claim and reimbursement data, meaning what’s billed, allowed, denied, and paid, and let it show you where the leaks are.
