The Soro Team January 2026 The best way to understand a bill review is to walk through one. What follows is an illustrative hospital bill, built to mirror the patterns we see rather than any single patient's. The bill totaled far more than the care supported, and the errors were exactly the kinds a careful audit is built to catch. Each one is money the patient was asked for and did not owe. ### The starting point: the itemized bill The statement in the mail showed a single large balance. That is where most people stop, because there is nothing on it to argue with. The itemized bill, requested from the hospital, is where the detail lives: every medication, procedure, supply, and room charge, each carrying its own code. Comparing that against the medical record is where every finding below came from. **Teardown · hospital stay** Illustrative 71046 Chest X-ray, billed twice $610 Duplicate 99285 ER visit, notes support level 3 $2,730 Upcoded 80053 One panel billed as 14 tests $1,340 Unbundled R&B 4 days billed, 3 nights stayed $3,912 Overstated Taken off one bill **$14,380** Figures are illustrative. ### Finding one: a duplicate scan A chest x-ray, two views, appeared twice on the same date at the same charge. The medical record showed one. The second was a duplicate, billed a second time for a service performed once. Duplicates are among the most common hospital billing errors because a busy billing system can post the same item more than once. The remedy is straightforward: remove it. ### Finding two: an upcoded visit The visit was billed at the highest complexity level. The physician's note described a routine follow-up that supported a lower one. This is upcoding: the code claimed more than the documentation showed. The correction is to reprice the line to the level the record actually supports and take the difference off. ### Finding three: an unbundled panel A basic metabolic panel was billed as fourteen separate assays rather than the single panel code that covers them. Under correct coding rules, the comprehensive panel code should have been used. Billing the components separately inflated the charge well above the panel price. This is unbundling, and the National Correct Coding Initiative edits are the standard that says the parts should have been billed as one. ### Finding four: an overstated stay Room and board was billed for four days. The admission and discharge records showed three. The extra day of room charges, along with everything that rode along with it, was billed for time the patient was not there. Length-of-stay errors are among the largest single-line corrections on a hospital bill because a day of room and board is expensive. ### Finding five: charged for what insurance already covered A balance that should have been settled at the insurer's contracted rate was billed to the patient anyway. Comparing the amount against the explanation of benefits and the allowed amount showed it should never have been passed on. Catching this required reading the bill against the EOB, not just the hospital's statement. ### The result Individually, several of these lines look small. Together, on one hospital stay, they added up to a five-figure reduction. None of them required a fight. Each required the itemized bill, the explanation of benefits, an objective coding or pricing standard, and a clearly documented request to correct the charge. That is the whole method, applied to one bill. ### References 1. Illustrative composite bill; figures represent typical error patterns and are not tied to any real patient. 2.
