What happens during a bill review
When a provider submits a bill for treatment related to a workers' compensation claim, that bill has to be checked against several layers of rules before it can be paid: whether the billing codes are valid and correctly documented, which fee schedule or contracted rate applies to each line, whether any bundling, multiple-procedure, or modifier rules affect the billed amount, and whether the total bill is internally consistent. Medical bill review is the umbrella term for this entire validation and pricing process, distinct from the clinical question of whether the underlying treatment was appropriate in the first place, which is handled through utilization review and medical necessity determinations instead.
Line-item adjudication vs. bundling
Bill review generally operates at two levels simultaneously. Line-item adjudication evaluates each individual billed service on its own, applying the correct fee schedule rate, modifiers, and place-of-service adjustments. Bundling rules then look across multiple lines on the same bill (or across related bills for the same encounter) to determine whether certain services should be reimbursed together rather than separately, such as a follow-up visit bundled into a global surgical package, or supplies considered incidental to a primary procedure. Getting the line-item pricing right without correctly applying bundling logic (or the reverse) is one of the most common sources of bill review error.
Common review steps
A typical bill review workflow moves through several stages: bill entry (capturing the billed data, historically through manual entry or OCR from a scanned CMS-1500 or UB-04 form, or increasingly through structured EDI transactions), coding and documentation validation, pricing against the applicable fee schedule or contract, application of an audit rules engine to flag anomalies or policy violations, and final adjudication that produces a reduction or allowed amount with supporting documentation, often summarized in an Explanation of Review (EOR) or Explanation of Benefits (EOB).
Why bill review has historically been slow and opaque
Because these steps have traditionally relied on manual review, disconnected pricing systems, and vendor-specific rule engines, bill review has often taken minutes, hours, or even days per bill, with limited visibility into exactly why a reduction was applied. Providers and payers alike are frequently left with a final allowed amount but no clear, auditable path back to the specific rule, fee schedule citation, or calculation that produced it.
How BillSentry approaches medical bill review
BillSentry automatically identifies the applicable workers' compensation reimbursement methodology and calculates the allowed amount at the bill-line level in real time, applying fee schedule pricing, bundling logic, and audit rules consistently across every bill.
