A Service Line on the Verge of Reduction — Saved by Accurate Data
A regional health system was reporting Orthopedics contribution margin at 11.3% — well below the internal reinvestment threshold. Leadership was deprioritizing OR block time and entertaining program reduction. The margin was not broken. The data was.

Root Cause
What the Data Was Actually Telling Them
A workflow gap between the vendor invoice process in Oracle AP and Epic charge capture was causing implant costs to post to a facility-wide supply materials cost center — rather than mapping to the orthopedic procedure codes where they belonged.
- EDI 832 GPO contract feeds were not reconciled against actual implant utilization by CPT code
- Three Epic charge router failure points allowed costs to fall through to the default cost center
- No governance checkpoint existed between vendor invoicing and service line reporting
- The error compounded across 22 months, distorting trend data used for OR scheduling decisions
Outcomes
Strategic Decisions Reversed. Program Preserved.

"The margin problem wasn't in the operating room. It was in the workflow between the loading dock and the general ledger. Once you see it, you can't unsee it — and you can't afford to leave it unaddressed."
